What is (are) Central serous chorioretinopathy ? | Central serous chorioretinopathy is a disease that causes fluid to build up under the retina, the back part of the inner eye that sends sight information to the brain. The fluid leaks from the choroid (the blood vessel layer under the retina). The cause of this condition is unknown but stress can be a risk factor. Signs and symptoms include dim and blurred blind spot in the center of vision, distortion of straight lines and seeing objects as smaller or farther away. Many cases of central serous chorioretinopathy improve without treatment after 1-2 months. Laser treatment may be an option for other individuals. | |
What is (are) Scleroderma ? | Scleroderma is an autoimmune disorder that involves changes in the skin, blood vessels, muscles, and internal organs. There are two main types: localized scleroderma, which affects only the skin; and systemic scleroderma, which affects the blood vessels and internal organs, as well as the skin. These two main types also have different sub-types. Localized scleroderma can be divided in: Linear scleroderma (en coup de sabre) Morphea (localized, generalized, guttata and deep). Systemic scleroderma is subdivided in: Diffuse cutaneous systemic sclerosis Limited cutaneous systemic sclerosis (which includes CREST syndrome) Limited Systemic Sclerosis (or systemic sclerosis sine scleroderm). There are also cases of environmentally-induced scleroderma and cases where scleroderma is part of other rheumatic disorders, like rheumatoid arthritis, lupus or Sjogren syndrome. The underlying cause of scleroderma is currently unknown; however, some scientists suspect that it may be related to a buildup of collagen in the skin and other organs due to an abnormal immune system response. There is no cure, but various treatments can relieve symptoms. | |

What is (are) Guttate psoriasis ? | Guttate psoriasis is a skin condition in which small, red, and scaly teardrop-shaped spots appear on the arms, legs, and middle of the body. It is a relatively uncommon form of psoriasis. The condition often develops very suddenly, and is usually triggered by an infection (e.g., strep throat, bacteria infection, upper respiratory infections or other viral infections). Other triggers include injury to the skin, including cuts, burns, and insect bites, certain malarial and heart medications, stress, sunburn, and excessive alcohol consumption. Treatment depends on the severity of the symptoms, ranging from at-home over the counter remedies to medicines that suppress the body's immune system to sunlight and phototherapy. | |
What are the treatments for Guttate psoriasis ? | How might guttate psoriasis be treated? The goal of treatment is to control the symptoms and prevent secondary infections. Mild cases of guttate psoriasis are usually treated at home. The following may be recommended: Cortisone (anti-itch and anti-inflammatory) cream Dandruff shampoos (over-the-counter or prescription) Lotions that contain coal tar Moisturizers Prescription medicines containing vitamin D or vitamin A (retinoids) People with very severe guttate psoriasis may take medicines to suppress the body's immune system. These medicines include corticosteroids, cyclosporine, and methotrexate. Sunlight may help some symptoms go away. Care should be taken to avoid sunburn. Some people may choose to have phototherapy. Phototherapy is a medical procedure in which the skin is carefully exposed to ultraviolet light. Phototherapy may be given alone or after taking a drug that makes the skin more sensitive to light. More detailed information related to the treatment of psoriasis can be accessed through Medscape Reference. The National Psoriasis Foundation can also provide you with information on treatment. | |
What is (are) Polycystic liver disease ? | Polycystic liver disease is an inherited condition characterized by many cysts of various sizes scattered throughout the liver. Abdominal discomfort from swelling of the liver may occur; however, most affected individuals do not have any symptoms. In some cases, polycystic liver disease appears to occur randomly, with no apparent cause. Most cases are inherited in an autosomal dominant fashion. Sometimes, cysts are found in the liver in association with the presence of autosomal dominant polycystic kidney disease (AD-PKD). In fact, about half of the people who have AD-PKD experience liver cysts. However, kidney cysts are uncommon in those affected by polycystic liver disease. | |

What is (are) Chromosome 3p- syndrome ? | Chromosome 3p- syndrome is a rare chromosome abnormality that occurs when there is a missing copy of the genetic material located towards the end of the short arm (p) of chromosome 3. The severity of the condition and the signs and symptoms depend on the exact size and location of the deletion and which genes are involved. Some affected people appear to have no features or mild features, while others are more severely affected. Common symptoms shared by many people with this deletion include poor growth, developmental delay, intellectual disability, distinctive facial features, autism spectrum disorder, an unusually small head (microcephaly), and poor muscle tone (hypotonia). Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person. | |

What causes Chromosome 3p- syndrome ? | What causes chromosome 3p- syndrome? In most people with chromosome 3p- syndrome, the deletion occurs as a new mutation (called a de novo mutation) and is not inherited from a parent. De novo mutations are due to a random error that occurs during the formation of egg or sperm cells, or shortly after conception. In a few cases, the deletion is inherited from a parent. | |
Is Chromosome 3p- syndrome inherited ? | Is chromosome 3p- syndrome inherited? In most cases, chromosome 3p- syndrome occurs for the first time in the affected person (de novo mutation). However, the deletion is rarely inherited from a parent. In these cases, the deletion is passed down in an autosomal dominant manner. This means that a person with chromosome 3p- syndrome has a 50% chance with each pregnancy of passing the condition on to his or her child. In theory, it is possible for a parent to not have the deletion in their chromosomes on a blood test, but have the deletion in some of their egg or sperm cells only. This phenomenon is called germline mosaicism. In these rare cases, it would be possible to have another child with the deletion. To our knowledge, this has not been reported with chromosome 3p- syndrome. People interested in learning more about genetic risks to themselves or family members should speak with a genetics professional. | |
How to diagnose Chromosome 3p- syndrome ? | How is chromosome 3p- syndrome diagnosed? There are several different specialized tests that can be used to diagnose a chromosome 3p- syndrome. These include: Karyotype - a karyotype is a laboratory test that produces an image of a person's chromosomes. This test can be used to diagnose large deletions. FISH - a laboratory technique that is used to detect and locate a specific DNA sequence on a chromosome. During FISH, a chromosome is exposed to a small DNA sequence called a probe that has a fluorescent molecule attached to it. The probe sequence binds to its corresponding sequence on the chromosome. This test can be used in combination with karyotyping for deletions that are too small to be seen on karyotype, alone. However, FISH is only useful if the person ordering the test suspects there is a duplication of a specific region of 3p. Array CGH - a technology that detects deletions that are too small to be seen on karyotype. | |
What are the treatments for Chromosome 3p- syndrome ? | How might chromosome 3p- syndrome be treated? Because chromosome 3p- syndrome affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this deletion varies based on the signs and symptoms present in each person. For example, children with delayed motor milestones (i.e. walking) and/or muscle problems may be referred for physical or occupational therapy. Severe feeding difficulties may be treated temporarily with a nasogastric tube or a gastrostomy tube to ensure that a baby or child gets enough nutrients. Certain medications may be prescribed to treat seizures. Special education services are often necessary for children with intellectual disability. Surgery may be required to treat certain physical abnormalities such as cleft palate or congenital heart defects, if present. Please speak to your healthcare provider if you have any questions about your personal medical management plan. | |
What is (are) Congenital myasthenic syndrome ? | Congenital myasthenic syndrome (CMS) is a group of genetic disorders that result in muscle weakness and fatigue. Symptoms can range from mild weakness to progressive disabling weakness. There are three main subtypes of CMS, which are defined by how they affect the connection between muscles and the nervous system: postsynaptic (75-80% of patients), synaptic (14-15% of patients), and presynaptic (7-8% of patients). Identification of the specific subtype is important in patient care for determining the most effective treatment. Mutations in many genes have been found to cause CMS, and most forms of CMS are inherited in an autosomal recessive pattern. One form of CMS, a postsynaptic form known as slow-channel syndrome congenital myasthenic syndrome is inherited in an autosomal dominant manner. | |
Is Congenital myasthenic syndrome inherited ? | How is congenital myasthenic syndrome inherited? Almost all types of CMS are inherited in an autosomal recessive manner. In order to have the autosomal recessive form of CMS, both parents of an affected individual must be carriers of the disease causing mutation. If a person has CMS, but their partner is not a carrier of a CMS mutation, then their children will be carriers but will not have CMS. If one person has CMS and one person is a carrier of CMS, each child has a 50% chance of either being a carrier of CMS or having the disorder. Only one form of CMS (slow-channel syndrome congenital myasthenic syndrome) has been shown to be inherited in an autosomal dominant manner. This means that if one parent has slow-channel syndrome congenital myasthenic syndrome then all of their children have a 50% chance of inheriting the disorder as well. It is important to discuss this information with your health care provider, such as a genetic counselor, to accurately determine a person's risk for passing on this disorder. | |

What is (are) Fibrous dysplasia ? | Fibrous dysplasia is a skeletal disorder that is characterized by the replacement of normal bone with fibrous bone tissue. It may involve one bone (monostotic) or multiple bones (polyostotic). Fibrous dysplasia can affect any bone in the body. The most common sites are the bones in the skull and face, the long bones in the arms and legs, the pelvis, and the ribs. Though many individuals with this condition do not have any symptoms, others may have bone pain, abnormally shaped bones, or an increased risk of fractures (broken bones). This condition can occur alone or as part of a genetic disorder, such as McCune-Albright syndrome. While there is no cure for fibrous dysplasia, the symptoms can be treated. Medications known as bisphosphonates can reduce pain and surgery may be indicated for fractures or to correct misshapen bones. | |
What are the symptoms of Fibrous dysplasia ? | What are the symptoms of fibrous dysplasia? Fibrous dysplasia may cause no symptoms, mild symptoms, or severe symptoms. The most common symptoms are bone pain, bone deformities, fractures, and skin pigmentation differences (light brown spots on the skin). The problems that a person experiences depend on the specific bone(s) affected. For example, if the legs are of different lengths, they might limp when they walk; if the bones in the sinuses are affected, chronic sinus congestion may be a present. In rare cases, fibrous dysplasia is associated with abnormalities in the hormone-producing glands of the endocrine system. This may lead to precocious puberty, hyperthyroidism (excess thyroid hormone production), excess growth hormone (gigantism or acromegaly), and/or excess cortisol production (Cushing syndrome). If the face or skull bones are affected, hearing or vision loss may occur. | |
What causes Fibrous dysplasia ? | What causes fibrous dysplasia? The cause of fibrous dysplasia has been linked to a gene mutation that occurs after conception, in the early stages of fetal development. The mutation involves a gene that affects the cells that produce bone. People with fibrous dysplasia carry this mutation in some, but not all cells of their body. It is not well understood why the mutation occurs, but it is not inherited from a parent, nor can it be passed on to future offspring. | |
What are the treatments for Fibrous dysplasia ? | How might fibrous dysplasia be treated? Unfortunately, there is no cure for fibrous dysplasia. Treatment depends on the symptoms that develop. Fractures often require surgery, but can sometimes be treated with casting or splints.] Surgery is most appropriate in cases where fractures are likely to occur, or where bones have become misshapen. Surgery may also be used to relieve pain. Medications known as bisphosphonates are also used to relieve bone pain. Other healthy strategies such as physical activity and adequate intake of calcium, phosphorus, and vitamin D are also encouraged.[ Radiation therapy is not recommended for patients with fibrous dysplasia because it is associated with an increased risk of cancerous transformation. Careful, long-term follow-up to monitor fibrous dysplasia is advised. | |
What is (are) Schistosomiasis ? | Schistosomiasis is a disease caused by parasitic worms. Although the worms that cause schistosomiasis are not found in the United States, more than 200 million people are infected worldwide. Infection occurs through contact with contaminated water. The parasite in its infective stages is called a cercaria. It swims freely in open bodies of water. On contact with humans, the parasite burrows into the skin, matures into another stage (schistosomula), then migrates to the lungs and liver, where it matures into the adult form. The adult worm then migrates to its preferred body part (bladder, rectum, intestines, liver, portal venous system (the veins that carry blood from the intestines to liver, spleen, lungs), depending on its species. Schistosomiasis is common in many tropical and subtropical areas worldwide. It can be treated safely and effectively with praziquantel. | |
What are the symptoms of Schistosomiasis ? | What are the signs and symptoms of Schistosomiasis? The Human Phenotype Ontology provides the following list of signs and symptoms for Schistosomiasis. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the immune system - Autosomal dominant inheritance - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | |
How to diagnose Schistosomiasis ? | How is schistosomiasis diagnosed? Examination of stool and/or urine for ova is the primary method of diagnosis for schistosomiasis. The choice of sample depends on the suspected species, which may be determined by careful review of travel and residence history. The sensitivity of this testing can be limited by the intensity of infection. For best results, three samples should be collected on different days. A blood sample can also be tested for evidence of infection. Blood tests are indicated for travelers or immigrants from endemic areas who have not been treated (or not treated appropriately) in the past. The most common tests detect antibodies to the adult worm. For accurate results, the blood sample tested should be collected at least 6 to 8 weeks after likely infection. Blood testing may not be appropriate for patients who have been repeatedly infected and treated in the past because antibodies can persist despite cure. In these patients, blood testing cannot distinguish between a past or current infection. A specific blood test has been developed for this population (which can detect an active infection based on the presence of schistosomal antigen), but this test is not commercially available in the United States and is currently being studied for its ability to detect mild infections. | |
What is (are) Dent disease 1 ? | Dent disease type 1 is a kidney disease seen mostly in males. The most frequent sign of Dent disease is the presence of an abnormally large amount of protein in the urine (proteinuria). Other common signs of the disorder include excess calcium in the urine (hypercalciuria), calcium deposits in the kidney (nephrocalcinosis), and kidney stones (nephrolithiasis). In many males with Dent disease, progressive kidney problems lead to end-stage renal disease (ESRD) in early to mid-adulthood. ESRD ia a failure of kidney function that occurs when the kidneys are no longer able to effectively filter fluids and waste products from the body. Disease severity can vary even among members of the same family. Dent disease type 1 is inherited in an X-linked recessive manner. Approximately 60% of individuals with Dent disease 1 have a mutation in the CLCN5 gene which is located on the X chromosome. Due to random X-chromosome inactivation, some female carriers may manifest hypercalciuria and, rarely, proteinuria. | |

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | |
What is (are) 22q11.2 deletion syndrome ? | 22q11.2 deletion syndrome is a spectrum disorder that includes conditions formerly called DiGeorge syndrome; velocardiofacial syndrome; conotruncal anomaly face syndrome; cases of Opitz G/BBB syndrome; and Cayler cardiofacial syndrome. The features and severity can vary greatly among affected people. Signs and symptoms may include cleft palate, heart defects, recurrent infections, unique facial characteristics, feeding problems, immune system disorders, kidney abnormalities, hypoparathyroidism, thrombocytopenia, scoliosis, hearing loss, developmental delay, and learning disabilities. People with this condition are also more likely to develop certain autoimmune disorders and personality disorders. In most cases, the syndrome occurs for the first time in the affected person; about 10% of cases are inherited from a parent. It is inherited in an autosomal dominant manner. | |

What causes 22q11.2 deletion syndrome ? | What causes 22q11.2 deletion syndrome? 22q11.2 deletion syndrome is caused by a missing piece (deletion) of part of chromosome 22 in each cell. The deletion occurs near the middle of the chromosome at a location designated q11.2. Most people with 22q11.2 deletion syndrome are missing a piece of the chromosome that contains about 30 to 40 genes, many of which have not been well characterized. Some affected people have smaller deletions. Researchers are working to learn more about all of the genes that contribute to the features of 22q11.2 deletion syndrome. The deletion of a particular gene, TBX1, is probably responsible for many of the syndrome's characteristic signs (such as heart defects, a cleft palate, distinctive facial features, hearing loss, and low calcium levels). Loss of this gene may also contribute to behavioral problems. The loss of another gene, COMT, may also cause increased risk of behavioral problems and mental illness in affected people. The other genes that are deleted likely contribute to the various features of 22q11.2 deletion syndrome. | |
Is 22q11.2 deletion syndrome inherited ? | Is 22q11.2 deletion syndrome inherited? Most cases of 22q11.2 deletion syndrome are not inherited from a parent and are caused by a random error during the formation of egg or sperm cells, or during early fetal development. In about 10% of cases, the deletion is inherited from a parent with the deletion. All people with the deletion, whether they inherited it or not, can pass the deletion to their children. The inheritance pattern is autosomal dominant because having a deletion in only one copy of chromosome 22 in each cell is enough to cause signs and symptoms. Each child of a person with the deletion has a 50% (1 in 2) chance to inherit the deletion. | |
What is (are) Cockayne syndrome type II ? | Cockayne syndrome is a rare condition which causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. This syndrome also includes failure to thrive in the newborn, microcephaly, and impaired nervous system development. Other symptoms may include hearing loss, tooth decay, and eye and bone abnormalities. Cockayne syndrome type 1 (type A) is sometimes called classic or "moderate" Cockayne syndrome and is diagnosed during early childhood. Cockayne syndrome type 2 (type B) is sometimes referred to as the severe or "early-onset" type. This more severe form presents with growth and developmental abnormalities at birth. The third type, Cockayne syndrome type 3 (type C) is a milder form of the disorder. Cockayne syndrome is caused by mutations in either the ERCC8 (CSA) or ERCC6 (CSB) genes and is inherited in an autosomal recessive pattern. The typical lifespan for individuals with Cockayne syndrome type 1 is ten to twenty years. Individuals with type 2 usually do not survive past childhood. Those with type 3 live into middle adulthood. | |

What is (are) Succinic semialdehyde dehydrogenase deficiency ? | Succinic semialdehyde dehydrogenase (SSADH) deficiency is disorder that can cause a variety of neurological and neuromuscular problems. The signs and symptoms can be extremely variable among affected individuals and may include mild to severe intellectual disability; developmental delay (especially involving speech); hypotonia; difficulty coordinating movements (ataxia); and/or seizures. Some affected individuals may also have decreased reflexes (hyporeflexia); nystagmus; hyperactivity; and/or behavioral problems. SSADH deficiency is caused by mutations in the ALDH5A1 gene and is inherited in an autosomal recessive manner. Management is generally symptomatic and typically focuses on treating seizures and neurobehavioral issues. | |
What are the symptoms of Succinic semialdehyde dehydrogenase deficiency ? | What are the signs and symptoms of Succinic semialdehyde dehydrogenase deficiency? People with succinic semialdehyde dehydrogenase deficiency (SSADH) typically have developmental delay, especially involving speech development; intellectual disability; and decreased muscle tone (hypotonia) soon after birth. About half of those affected experience seizures, difficulty coordinating movements (ataxia), decreased reflexes, and behavioral problems. The most common behavioral problems associated with this condition are sleep disturbances, hyperactivity, difficulty maintaining attention, and anxiety. Less frequently, affected individuals may have increased aggression, hallucinations, obsessive-compulsive disorder (OCD), and self-injurious behavior, including biting and head banging. People with this condition can also have problems controlling eye movements. Less common features of SSADH include uncontrollable movements of the limbs (choreoathetosis), involuntary tensing of the muscles (dystonia), muscle twitches (myoclonus), and a progressive worsening of ataxia. The Human Phenotype Ontology provides the following list of signs and symptoms for Succinic semialdehyde dehydrogenase deficiency.

What causes Succinic semialdehyde dehydrogenase deficiency ? | What causes succinic semialdehyde dehydrogenase deficiency? Succinic semialdehyde dehydrogenase deficiency (SSADH) is caused by mutations in the ALDH5A1 gene. This gene provides instructions for producing the succinic semialdehyde dehydrogenase enzyme which is involved in the breakdown of a chemical that transmits signals in the brain (neurotransmitter) called gamma-amino butyric acid (GABA). The primary role of GABA is to prevent the brain from being overloaded with too many signals. A shortage (deficiency) of succinic semialdehyde dehydrogenase leads to an increase in the amount of GABA and a related molecule called gamma-hydroxybutyrate (GHB) in the body, particularly the brain and spinal cord (central nervous system). It is unclear how an increase in GABA and GHB causes developmental delay, seizures, and other signs and symptoms of succinic semialdehyde dehydrogenase deficiency. | |
Is Succinic semialdehyde dehydrogenase deficiency inherited ? | How is succinic semialdehyde dehydrogenase deficiency inherited? Succinic semialdehyde dehydrogenase deficiency (SSADH) is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. | |
How to diagnose Succinic semialdehyde dehydrogenase deficiency ? | How is succinic semialdehyde dehydrogenase deficiency diagnosed? The diagnosis of succinic semialdehyde dehydrogenase (SSADH) deficiency is based upon a thorough clinical exam, the identification of features consistent with the condition, and a variety of specialized tests. SSADH deficiency may first be suspected in late infancy or early childhood in individuals who have encephalopathy, a state in which brain function or structure is altered. The encephalopathy may be characterized by cognitive impairment; language deficit; poor muscle tone (hypotonia); seizures; decreased reflexes (hyporeflexia); and/or difficulty coordinating movements (ataxia). The diagnosis may be further suspected if urine organic acid analysis (a test that provides information about the substances the body discards through the urine) shows the presence of 4-hydroxybutyric acid. The diagnosis can be confirmed by an enzyme test showing deficiency of SSADH, or by genetic testing. ALDH5A1 is the only gene currently known to be associated with SSADH deficiency, and genetic testing can detect mutations in about 97% of affected individuals. | |
What are the treatments for Succinic semialdehyde dehydrogenase deficiency ? | How might succinic semialdehyde dehydrogenase deficiency be treated? Treatment of succinic semialdehyde dehydrogenase deficiency (SSADH) is generally symptomatic and typically focuses on the treatment of seizures and neurobehavioral disturbances. Antiepileptic drugs (AEDs) that have proven to be effective in treating the seizures associated with this condition include carbamazepine and lamotrigine (LTG). Medications such as methylphenidate, thioridazine, risperidal, fluoxetine, and benzodiazepines appear to be effective at treating anxiety, aggressiveness, inattention, and hallucinations. Additional treatments may include physical and occupational therapy, sensory integration, and/or speech therapy. | |
What is (are) Antley Bixler syndrome ? | Antley Bixler syndrome is a rare condition that is primarily characterized by craniofacial abnormalities and other skeletal problems. The signs and symptoms vary significantly from person to person but may include craniosynostosis; midface hypoplasia (underdeveloped middle region of the face); frontal bossing; protruding eyes; low-set, unusually-formed ears; choanal atresia or stenosis (narrowing); fusion of adjacent arm bones (synostosis); joint contractures; arachnodactyly; bowing of the thigh bones; and/or urogenital (urinary tract and genital) abnormalities. The exact underlying cause of Antley Bixler syndrome is unknown in many cases; however, some are due to changes (mutations) in the FGFR2 gene or the POR gene. There appear to be autosomal dominant and autosomal recessive forms of the condition. Treatment is based on the signs and symptoms present in each person. | |

What is (are) Central core disease ? | Central core disease (CCD) is an inherited condition that involves muscle weakness, skeletal abnormalities, and an increased chance of having a severe reaction to some anesthesia medications. Muscle weakness ranges from mild to severe and typically affects muscles in the trunk and upper legs, though muscles in the neck and face can also be affected. Skeletal abnormalities may include curving of the spine (scoliosis), dislocation of the hip, or restricted motion in certain joints (contractures). Some individuals with CCD have an increased chance of having a severe reaction to anesthesia, called malignant hyperthermia, which may cause muscle rigidity or break-down (rhabdomyolysis), a high fever, or a rapid heart beat. RYR1 is the only gene associated with CCD and clinical testing is available to look for disease-causing alterations in this gene known as mutations. | |

How to diagnose Central core disease ? | How is central core disease diagnosed? Because the symptoms of central core disease can be quite variable, a physical examination alone is often not enough to establish a diagnosis. A combination of the following examinations and testings can diagnosis this condition: a physical examination that confirms muscle weakness, a muscle biopsy that reveals a characteristic appearance of the muscle cells, and/or genetic testing that identifies a mutation in the RYR1. | |
What are the treatments for Central core disease ? | What treatments might be available for central core disease? Treatments for central core disease (CCD) depend on the symptoms experienced by each affected individual. When someone is first diagnosed with this condition, a physical examination is done to assess the extent and severity of muscle weakness, and physical therapy and occupational therapy assessments to determine which therapies might be most beneficial. Physical therapy, such as stretching or low-impact exercises, may help improve weakness. Some skeletal abnormalities can be addressed with physical therapy, though others may require surgery. As the muscle weakness and scoliosis associated with CCD can affect breathing, individuals diagnosed with this condition may benefit from pulmonary function tests. If breathing is significantly affected, breathing exercises or other breathing support treatments may be recommended. Another treatment option may be a medication called salbutamol, which was found to significantly increased muscle strength and stamina in six of eight children with CCD. | |

What is (are) Desmoplastic small round cell tumor ? | Desmoplastic small round cell tumors (DSRCT), a rare malignant cancer, is a soft tissue sarcoma that usually affects young boys and men and is found most often in the abdomen. Its name means that it is formed by small, round cancer cells surrounded by scarlike tissue. The most common symptoms include abdominal pain, abdominal mass and symptoms of gastrointestinal obstruction. DSRCTs are treated first with chemotherapy, then with surgery to remove the tumor, if possible. Radiation therapy is sometimes given, depending on the tumor. In addition, some people with DSRCT are candidates for a bone marrow transplant. | |

For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | |
What is (are) Schimke immunoosseous dysplasia ? | Schimke immunoosseous dysplasia (SIOD) is a condition characterized by short stature, kidney disease, and a weakened immune system. Growth failure is often the first sign of this condition. Other features are usually detected in the evaluation for growth failure or in the following years. The severity of SIOD ranges from an infantile or severe early-onset form to a juvenile or milder late-onset form. Complications of the severe form of SIOD can include strokes, severe opportunistic infections, bone marrow failure, and kidney failure that can be life-threatening early in life. People with milder disease have survived to adulthood if their kidney disease is managed. This condition is inherited in an autosomal recessive pattern. Mutations in the SMARCAL1 gene increase the risk to develop Schimke immunoosseous dysplasia. However, in order for people with SMARCAL1 gene mutations to develop symptoms of Schimke immunoosseous dysplasia, other currently unknown genetic or environmental factors must also be present. | |
What are the symptoms of Schimke immunoosseous dysplasia ? | What are the signs and symptoms of Schimke immunoosseous dysplasia? Schimke immunoosseous dysplasia is characterized by short stature, kidney disease, and a weakened immune system. In people with this condition, short stature is caused by flattened spinal bones (vertebrae), resulting in a shortened neck and trunk. Adult height is typically between 3 and 5 feet. Kidney (renal) disease often leads to life-threatening renal failure and end-stage renal disease (ESRD). Affected individuals also have a shortage of certain immune system cells called T cells. T cells identify foreign substances and defend the body against infection. A shortage of T cells causes a person to be more susceptible to illness. Other features frequently seen in people with this condition include an exaggerated curvature of the lower back (lordosis); darkened patches of skin (hyperpigmentation), typically on the chest and back; and a broad nasal bridge with a rounded tip of the nose. Less common signs and symptoms of Schimke immuno-osseous dysplasia include an accumulation of fatty deposits and scar-like tissue in the lining of the arteries (atherosclerosis), reduced blood flow to the brain (cerebral ischemia), migraine-like headaches, an underactive thyroid gland (hypothyroidism), decreased numbers of white blood cells (lymphopenia), underdeveloped hip bones (hypoplastic pelvis), abnormally small head size (microcephaly), a lack of sperm (azoospermia) in males, and irregular menstruation in females. In severe cases, many signs of Schimke immuno-osseous dysplasia can be present at birth. People with mild cases of this disorder may not develop signs or symptoms until late childhood. The Human Phenotype Ontology provides the following list of signs and symptoms for Schimke immunoosseous dysplasia.

How to diagnose Schimke immunoosseous dysplasia ? | How is Schimke immunoosseous dysplasia diagnosed? The diagnosis of SIOD is made on clinical findings. The most definitive diagnostic findings are skeletal dysplasia (spondyloepiphyseal dysplasia), renal dysfunction (urinary protein loss), T lymphocyte deficiency, characteristic facial features, and hyperpigmented macules. DNA testing for mutations in SMARCAL1 is available on a clinical basis. | |
What are the treatments for Schimke immunoosseous dysplasia ? | How might Schimke immunoosseous dysplasia be treated? Treatment of Schimke immunoosseous dysplasia (SIOD) is based on addressing individual symptoms as they develop. Renal transplantation can treat the renal disease, and bone marrow transplantation has been done to treat the immunodeficiency. Blood thinning medications can transiently improve blood flow through the atherosclerotic arteries but do not provide enduring relief from cerebral ischemia. Treatment with acyclovir and some antibacterial agents has been beneficial for preventing of reducing the frequency of opportunistic infections. More detailed information about treatment for SIOD can be found on the GeneReview's Web site. Click on the GeneReview link to read more. | |
What is (are) Schwannomatosis ? | Schwannomatosis is a rare form of neurofibromatosis that is primarily characterized by multiple schwannomas (benign tumors of the nervous system) in the absence of bilateral (affecting both sides) vestibular schwannomas. Signs and symptoms of the condition vary based on the size, location and number of schwannomas but may include pain; numbness; tingling; and/or weakness in the fingers and toes. Inherited forms of the disorder account for only 15 percent of all cases. In some of these families, schwannomatosis is caused by changes (mutations) in the SMARCB1 or LZTR1 genes; in other cases, the exact underlying cause is unknown. When inherited, the condition is passed down in an autosomal dominant manner with highly variable expressivity and reduced penetrance. Treatment is based on the signs and symptoms present in each person but may include medications and/or surgery. | |
What are the symptoms of Schwannomatosis ? | What are the signs and symptoms of Schwannomatosis? Signs and symptoms of the schwannomatosis often develop during adulthood between ages 25 and 30. Affected people generally have multiple schwannomas, which are benign tumors of the nervous system. In schwannomatosis, these tumors can grow along any nerve in the body, although they are less common on the vestibular nerve (vestibular schwannomas, also known as acoustic neuromas). People with vestibular schwannomas, especially those with tumors affecting the vestibular nerve on both sides of the head (bilateral), may have neurofibromatosis type 2 instead. The signs and symptoms associated with schwannomatosis vary based on the size and location of the schwannomas. The most common symptom is chronic pain, which can develop as a growing schwannoma presses on nerves or surrounding tissues. Some people may develop a mass if the schwannomas is located just beneath the skin. Others can experience neurological symptoms such as numbness; tingling; and/or weakness in the fingers and toes. The Human Phenotype Ontology provides the following list of signs and symptoms for Schwannomatosis. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common. | |
What causes Schwannomatosis ? | What causes schwannomatosis? Some cases of schwannomatosis are caused by changes (mutations) in the SMARCB1 or LZTR1 genes. SMARCB1 and LZTR1 are tumor suppressor genes, which means that they encode a protein that stops cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in these genes result in abnormal proteins that are unable to carry out their normal roles. This contributes to the development of the many different types of tumors found in schwannomatosis. When schwannomatosis is caused by a mutation in SMARCB1 or LZTR1, the affected person is typically born with one mutated copy of the gene in each cell and is, therefore, genetically predisposed to develop the tumors associated with the condition. For a tumor to form, two copies of the gene must be altered. The mutation in the second copy of the gene is considered a somatic mutation because it occurs during a person's lifetime and is not inherited. In affected people without a mutation in SMARCB1 or LZTR1, the underlying cause of the condition is unknown. | |
Is Schwannomatosis inherited ? | Is schwannomatosis inherited? Approximately 15% percent of all schwannomatosis cases are thought to be inherited. In these cases, the condition is thought to be inherited in an autosomal dominant manner with highly variable expressivity and reduced penetrance. This means that a person only needs a change (mutation) in one copy of the responsible gene in each cell to have a genetic predisposition to the tumors associated with schwannomatosis. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. People with an inherited form of schwannomatosis have a 50% chance with each pregnancy of passing the condition on to the next generation. | |
How to diagnose Schwannomatosis ? | How is schwannomatosis diagnosed? A diagnosis of schwannomatosis is often suspected based on the presence of characteristic signs and symptoms, especially if there are other family members with the condition. Additional testing can then be ordered to further support the diagnosis and rule out other conditions with similar features (namely, neurofibromatosis type 2). This may include: Tumor pathology confirming that the growths are, in fact, schwannomas Imaging studies, such as an MRI examining the vestibular nerve. It is important to rule out the presence of bilateral (affecting both sides) vestibular schwannomas which would be suggestive of neurofibromatosis type 2 rather than schwannomatosis Genetic testing for a change (mutation) in the SMARCB1 or LZTR1 genes. Unfortunately, genetic testing is not informative in all people affected by schwannomatosis. | |
What are the treatments for Schwannomatosis ? | How might schwannomatosis be treated? Treatment for schwannomatosis is based on the signs and symptoms present in each person. For example, pain is one of the most common symptoms of the condition. Treatment with medications such as gabapentin or pregabalin and the use of short-acting opioids and/or nonsteroidal anti-inflammatories for pain can be successful for many patients. If pain cannot be managed with other means or if the schwannomas are causing other symptoms, they can be surgically removed. However this treatment is often used as a last resort because surgery may put patients at risk of further neurologic problems. | |
What is (are) Hyperprolinemia type 2 ? | Hyperprolinemia type 2 results in an excess of a particular protein building block (amino acid), called proline, in the blood. This condition generally occurs when proline is not broken down properly by the body. Hyperprolinemia type 2 causes proline levels in the blood to be 10 to 15 times higher than normal, and it also causes high levels of a related compound called pyrroline-5-carboxylate. Some people with this condition develop mild mental retardation and seizures; however, the symptoms of this disorder vary in severity among affected individuals. | |
What are the symptoms of Hyperprolinemia type 2 ? | What are the signs and symptoms of Hyperprolinemia type 2?

What are the treatments for Hyperprolinemia type 2 ? | How might hyperprolinemia type 2 be treated? There is no specific treatment for hyperprolinemia type 2, even for those individuals who experience seizures. In general, if people with hyperprolinemia type 2 have symptoms, they are usually mild and do not require treatment. If seizures are present during childhood, they tend to disappear in adulthood. Attempts to reduce the amount of proline in an affected person's diet have resulted in only modest control of proline levels in the blood and have not reduced symptoms. | |
What is (are) Charcot-Marie-Tooth disease type 1E ? | Charcot-Marie-Tooth disease type 1E (CMT1E) is a form of Charcot-Marie-Tooth disease, which is a group of rare conditions that affect the peripheral nerves. Signs and symptoms of CMT1E generally become apparent between age 5 and 25 years, although the age of onset and disease severity can vary significantly from person to person. In general, CMT1E is associated with the typical features of Charcot-Marie-Tooth disease type 1 (progressive weakness of the feet and/or ankles; foot drop; atrophy of muscles below the knee; absent tendon reflexes of upper and lower extremities; and a decreased sensitivity to touch, heat, and cold in the feet and/or lower legs) in addition to hearing loss. CMT1E is caused by certain changes (mutations) in the PMP22 gene and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person. | |

What is (are) Von Willebrand disease ? | Von Willebrand disease is a bleeding disorder that slows the blood clotting process. People with this disease often experience bruising, nosebleeds, and prolonged bleeding or oozing following an injury, surgery, or having a tooth pulled. In severe cases, heavy bleeding occurs after minor injury or even in the absence of injury. Milder forms of Von Willebrand disease do not involve spontaneous bleeding, and the disease may become apparent only when abnormal bleeding occurs following surgery or a serious injury. Symptoms may change over time. Increased age, pregnancy, exercise, and stress may make bleeding symptoms may become less frequent. This disease is caused by mutations in the VWF gene and can have different inheritance patterns. | |

What causes Von Willebrand disease ? | What causes von Willebrand disease? Von Willebrand disease is typically an inherited disease caused by mutations in the VWF gene. The VWF gene provides instructions for making a blood clotting protein called von Willebrand factor, which is important for forming blood clots and preventing further blood loss after an injury. If von Willebrand factor does not function normally or too little of the protein is available, blood clots cannot form properly. VWF gene mutations that reduce the amount of von Willebrand factor or cause the protein to function abnormally (or not at all) are responsible for the signs and symptoms associated with the condition. These mutations may be inherited in an autosomal dominant or autosomal recessive manner, or may occur for the first time in the affected individual (known as a de novo mutation). Another form of the disorder, often considered a separate condition, is called acquired von Willebrand syndrome (AVWS). AVWS is not caused by gene mutations. This condition is typically seen in conjunction with other disorders and usually begins in adulthood. A list of disorders associated with AVWS is available from UpToDate. | |
Is Von Willebrand disease inherited ? | Is von Willebrand disease always inherited from a parent? Most, but not all, cases of von Willebrand disease (VWD) are inherited. The majority of cases of type 1 and type 2A, as well as type 2B and type 2M, are inherited in an autosomal dominant manner. VWD type 2N, type 3, and some cases of type 1 and type 2A are inherited in an autosomal recessive manner. Most individuals with an autosomal dominant type of VWD have an affected parent. However, some individuals are affected due to having a new (de novo) mutation in the VWF gene that occurred for the first time in the affected individual. If the mutation found in the affected individual cannot be detected in either parent, it is most often due to a de novo mutation but may also be due to germline mosaicism in a parent. Possible non-medical explanations which may be explored include alternate paternity or maternity (e.g., with assisted reproduction) or undisclosed adoption. There is also a separate, rare condition called acquired von Willebrand syndrome (AVWS). This is a mild to moderate bleeding disorder that is typically seen in conjunction with other disorders, such as diseases that affect bone marrow or immune cell function. AVWS is not caused by a mutation in the VWF gene and usually begins in adulthood. | |
What is (are) Gangliocytoma ? | Gangliocytoma is a rare type of central nervous system (CNS) tumor made up of mature neurons. Gangliocytomas may occur in all age groups but most often occur in people between the ages of 10 and 30. The most common site is the temporal lobe of the brain, but they can arise anywhere in the CNS including the cerebellum, brainstem, floor of the third ventricle, and spinal cord. They are among the most frequent tumors associated with epilepsy. Signs and symptoms may depend on the tumor's location and may include seizures (most commonly); increased brain pressure; endocrine disorders; and focal symptoms. Gangliocytomas are generally slow-growing and usually do not become malignant. Treatment involves surgical removal of the tumor.

What are the symptoms of Gangliocytoma ? | What are the signs and symptoms of gangliocytomas? Signs and symptoms caused by the presence of a gangliocytoma can vary depending on the tumor's location. Seizures are the most common symptom. Other symptoms may include increased brain pressure, endocrine disorders, and focal symptoms. Gangliocytomas can also be asymptomatic (cause no symptoms) and may be diagnosed incidentally on imaging studies. | |

What is (are) Multicentric Castleman Disease ? | Multicentric Castleman disease (MCD) is a rare condition that affects the lymph nodes and related tissues. It is a form of Castleman disease that is "systemic" and affects multiple sets of lymph nodes and other tissues throughout the body (as opposed to unicentric Castleman disease which has more "localized" effects). The signs and symptoms of MCD are often nonspecific and blamed on other, more common conditions. They can vary but may include fever; weight loss; fatigue; night sweats; enlarged lymph nodes; nausea and vomiting; and an enlarged liver or spleen. The eact underlying cause is unknown. Treatment may involve immunotherapy, chemotherapy, corticosteroid medications and/or anti-viral drugs. | |

They can vary but may include: Fever Enlarged lymph nodes Night sweats Loss of appetite and weight loss Weakness and fatigue Shortness of breath Nausea and vomiting Enlarged liver or spleen Peripheral neuropathy Skin abnormalities such as rashes and/or pemphigus Less commonly (<10% of cases), people affected by MCD will have no signs or symptoms of the condition. Other conditions associated with MCD include amyloidosis, POEMS syndrome, autoimmune disease, hemolytic anemia, and immune thrombocytopenic purpura (ITP). | |
What causes Multicentric Castleman Disease ? | What causes multicentric Castleman disease? The exact underlying cause of multicentric Castleman disease (MCD) is poorly understood. However, some scientists suspect that an increased production of interleukin-6 (IL-6) by the immune system may contribute to the development of MCD. IL-6 is a substance normally produced by cells within the lymph nodes that helps coordinate the immune response to infection. Increased production of IL-6 may result in an overgrowth of lymphatic cells, leading to many of the signs and symptoms of MCD. It has also been found that a virus called human herpes virus type 8 (also known as HHV-8, Kaposi's sarcoma-associated herpesvirus, or KSHV) is present in many people with MCD. HHV-8 is found in nearly all people who are HIV-positive and develop MCD, and in up to 60% of affected people without HIV. The HHV-8 virus may possibly cause MCD by making its own IL-6. | |
Is Multicentric Castleman Disease inherited ? | Is multicentric Castleman disease inherited? Although the exact underlying cause of multicentric Castleman disease is unknown, it is thought to occur sporadically in people with no family history of the condition. | |
How to diagnose Multicentric Castleman Disease ? | How is multicentric Castleman disease diagnosed? The signs and symptoms of multicentric Castleman disease (MCD) are often nonspecific and blamed on other, more common conditions. However, if MCD is suspected, the following tests may be recommended to help establish the diagnosis and rule out other conditions that cause similar features: Blood tests can be ordered to evaluate the levels of Interleukin-6 (IL-6) and other substances in the body, which can be elevated in people with MCD. They can also be helpful in ruling out other autoimmune conditions and infections that are associated with similar signs and symptoms Imaging studies (such as a CT scan, PET scan, MRI scan, and/or ultrasound) can help identify enlarged lymph node(s) and other health problems A biopsy of affected tissue, often a lymph node, is usually recommended to confirm the diagnosis | |
What are the treatments for Multicentric Castleman Disease ? | How might multicentric Castleman disease be treated? The treatment of multicentric Castleman disease (MCD) varies based on the severity of the condition and whether or not the patient has an HIV and/or human herpes virus type 8 (HHV-8) infection. Possible treatment options include: Immunotherapy can be used to block the action of the interleukin-6 (IL-6), a protein that is produced in excess by the immune system of people with MCD Chemotherapy may be recommended to slow the growth of lymphatic cells Corticosteroid medications can reduce inflammation Anti-viral drugs can block the activity of HHV-8 or HIV (in people who are infected by these viruses) | |

What is (are) Mycobacterium Malmoense ? | Mycobacterium malmoense (M. malmoense) is a bacterium naturally found in the environment, such as in wet soil, house dust, water, dairy products, domestic and wild animals, food, and human waste. M. malmoense infections most often occur in adults with lung disease, and manifests as a lung infection. Skin and tissue infections with M. malmoense have also been described. In young children, M. Malmoense may cause an infection of lymphnodes in the neck (i.e., cervical lymphadenitis). | |
What are the symptoms of Mycobacterium Malmoense ? | What are the signs and symptoms of mycobacterium malmoense infection? Many cases of M. malmoense infection cause no symptoms, and as a result go unrecognized. M. malmoense infections in adults often present as lung infections with or without fever. In children, M. malmoense infections can present as a single sided, non-tender, enlarging, neck mass. The mass may be violet in color and often does not respond to conventional antibiotic therapy. M. malmoense infection can also cause skin lesions or abscesses. | |
What causes Mycobacterium Malmoense ? | How are mycobacterium malmoense infections contracted? M. Malmoense infection may be acquired by breathing in or ingesting the bacteria, or through trauma, such as an injury or surgical incision. People who have suppressed immune systems are at an increased risk for developing signs and symptoms from these infections. | |
What is (are) Renal nutcracker syndrome ? | Renal nutcracker syndrome (NCS) is a condition that occurs when the left renal vein (the vein that carries blood purified by the left kidney) becomes compressed. The signs and symptoms of the condition can vary from person to person. Some affected people may be asymptomatic while others develop severe and persistent symptoms. When present, features of NCS may include blood in the urine (hematuria), orthostatic proteinuria, flank pain and/or abdominal pain. Some cases of mild NCS in children may be due to changes in body proportions associated with growth. Why NCS occurs or becomes symptomatic in adults is less clear. Treatment ranges from surveillance to surgical intervention and is based on the severity of symptoms and their expected reversibility when considering the affected person's age and stage of the syndrome. | |

The signs and symptoms of renal nutcracker syndrome and the disease severity can vary from person to person. Some affected people may be asymptomatic while others have severe and persistent symptoms. Symptoms are often aggravated by physical activity. When present, symptoms of the condition may include blood in the urine (hematuria), orthostatic proteinuria, flank pain and/or abdominal pain. Some people may also experience orthostatic intolerance, which is characterized by symptoms such as light-headedness, palpitations, poor concentration, fatigue, nausea, dizziness, headache, sweating, weakness and occasionally fainting when upright standing. Men who are affected by renal nutcracker syndrome may develop a varicocele. Affected women may have gynecological symptoms such as dyspareunia and dysmenorrhea (painful periods). | |
Is Renal nutcracker syndrome inherited ? | Is renal nutcracker syndrome inherited? Renal nutcracker syndrome is not inherited. Most cases occur sporadically in people with no family history of the condition. Although more than one family member may rarely be affected, this is thought to be a coincidence and not the result of a genetic predisposition. | |
How to diagnose Renal nutcracker syndrome ? | How is Renal nutcracker syndrome diagnosed? A diagnosis of renal nutcracker syndrome is often suspected based on the presence of characteristic signs and symptoms once other conditions that cause similar features have been ruled out. Additional testing can then be ordered to support the diagnosis. This may include urine tests, imaging studies of the kidneys (i.e. doppler ultrasonography, computed tomography angiography, magnetic resonance angiography, retrograde venography), and/or cystoscopy. | |
What are the treatments for Renal nutcracker syndrome ? | How might renal nutcracker syndrome be treated? Treatment of renal nutcracker syndrome is based on severity of symptoms and their expected reversibility when considering the affected person's age and stage of the syndrome. Adults with mild cases and affected children may be treated conservatively with regular surveillance. People younger than 18 years, specifically, are often observed for at least 2 years because as many as 75% will have complete resolution of symptoms without any significant intervention. ACE inhibitors may be effective in treating orthostatic proteinuria. In those with severe symptoms who do not respond to more conservative treatments, surgery is often recommended. | |
What is (are) Tubular aggregate myopathy ? | Tubular aggregate myopathy is a very rare muscle disease where the presence of tubular aggregates represent the major, if not sole, pathologic change in the muscle cell. It is often characterized by muscle weakness or stiffness, cramps, and exercise induced muscle fatigue. The exact cause of the condition is unknown. Sporadic and genetic forms have been reported. Some cases appear to be due to dominant mutations in the STIM1 gene. | |
What are the symptoms of Tubular aggregate myopathy ? | What are the signs and symptoms of Tubular aggregate myopathy? In general, many people with tubular aggregate myopathy have muscle weakness, muscle cramps, and exercise induced fatigue. Typically the facial muscles are not affected in tubular aggregate myopathy. The Human Phenotype Ontology provides the following list of signs and symptoms for Tubular aggregate myopathy. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the pupil 5% External ophthalmoplegia 5% Flexion contracture 5% Nyctalopia 5% Respiratory insufficiency 5% Adult onset - Areflexia of lower limbs - Autosomal dominant inheritance - Difficulty running - Easy fatigability - Elevated serum creatine phosphokinase - Exercise-induced myalgia - Frequent falls - Hyporeflexia of lower limbs - Increased variability in muscle fiber diameter - Muscle cramps - Muscle stiffness - Myopathy - Proximal amyotrophy - Proximal muscle weakness - Slow progression - Type 2 muscle fiber atrophy - Weakness of the intrinsic hand muscles - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. Are there different types of tubular aggregate myopathy? Yes. Symptoms of tubular aggregate myopathy can be be grouped into at least three different types. The first type is characterized by exercise induced cramps with or without muscle pain associated or not with weakness in the proximal muscles. The second type of tubular aggregate myopathy is characterized by isolated, slowly progressive weakness of the proximal muscles. The third type is characterized by progressive proximal weakness and sometimes fatigability. In this type the serum creatine kinase levels are often elevated. | |
What causes Tubular aggregate myopathy ? | What causes tubular aggregate myopathy? Currently, the underlying cause of tubular aggregate myopathy is not known. Some cases appear to be due to dominant mutations in the STIM1 gene. | |
Is Tubular aggregate myopathy inherited ? | Is tubular aggregate myopathy genetic? It is evident from family history studies that the condition can be passed through families in either an autosomal dominant or autosomal recessive fashion. Some cases appear to be due to dominant mutations in the STIM1 gene. Sporadic cases of tubular aggregate myopathy have also been reported. Sporadic is used to denote either a genetic disorder that occurs for the first time in a family due to a new mutation or the chance occurrence of a non-genetic disorder or abnormality that is not likely to recur in a family. | |

What is (are) Congenital adrenal hyperplasia ? | Congenital adrenal hyperplasia (CAH) refers to a group of genetic conditions that affect the adrenal glands. These glands sit on top of the kidneys and are responsible for releasing various types of hormones that the body needs to function. Affected people lack an enzyme the adrenal glands need to make one or more of these hormones and often overproduce androgens (male hormones such as testosterone). The signs and symptoms present in each person depend on many factors including the type of CAH, the age of diagnosis, and the sex of the affected person. For example, females with a severe form of the condition may have ambiguous genitalia at birth and if not properly diagnosed, develop dehydration, poor feeding, diarrhea, vomiting and other health problems soon after. People with milder forms may not be diagnosed with the condition until adolescence or adulthood when they experience early signs of puberty or fertility problems. Treatment for CAH varies but may include medication and/or surgery. | |
What are the symptoms of Congenital adrenal hyperplasia ? | What are the signs and symptoms of Congenital adrenal hyperplasia? The signs and symptoms of congenital adrenal hyperplasia (CAH) vary based on many factors including the type of CAH, the age of diagnosis and the sex of the affected person. For example, girls with the severe form of CAH may be born with ambiguous genitalia, which often allows the condition to be diagnosed before other associated health problems such as poor feeding, vomiting, dehydration, and abnormal heart beat, can develop. Males typically appear unaffected at birth even when they have a severe form of CAH and without proper diagnosis, will develop associated health problems within 2-3 weeks after birth. Both genders can experience other symptoms such as early onset of puberty, fast body growth, and premature completion of growth leading to short stature, if they are not treated in early life. People affected by milder forms may not have any signs and symptoms of CAH during childhood. In these cases, a diagnosis may not be made until adolescence or adulthood when the affected person experiences early signs of puberty or fertility problems. Females with this type may have excessive facial or body hair; irregular menstrual periods; and/or acne. There are two main types of CAH: classic CAH, the more severe form, and a milder form called nonclassic CAH.

What causes Congenital adrenal hyperplasia ? | What causes congenital adrenal hyperplasia? Congenital adrenal hyperplasia (CAH) is a group of genetic conditions that can be caused by a change (mutation) in several different genes: 21-hydroxylase deficiency is caused by mutations in the CYP21A2 gene 3-beta-hydroxysteroid dehydrogenase deficiency is caused by mutations in the HSD3B2 gene 11-beta-hydroxylase deficiency is caused by mutations in the CYP11B1 gene Cytochrome P450 oxidoreductase deficiency is caused by mutations in the POR gene 17-hydroxylase deficiency is caused by mutations in the CYP17A1 gene Congenital lipoid adrenal hyperplasia is caused by mutations in the STAR gene Most of these genes encode enzymes that the adrenal glands need to make one or more hormones. The adrenal glands are cone-shaped organs that sit on top of the kidneys and are responsible for releasing various types of hormones that the body needs to function. Mutations in these genes lead to deficient levels of enzymes which cause low levels of hormones such as cortisol and/or aldosterone and an overproduction of androgens (male hormones such as testosterone). Cortisol is a hormone that affects energy levels, blood sugar levels, blood pressure, and the body's response to stress, illness, and injury. Aldosterone helps the body maintain the proper level of sodium (salt) and water and helps maintain blood pressure. Irregular levels of these hormones lead to the signs and symptoms of CAH. | |
Is Congenital adrenal hyperplasia inherited ? | How is congenital adrenal hyperplasia inherited? All forms of congenital adrenal hyperplasia (CAH) are inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. | |
How to diagnose Congenital adrenal hyperplasia ? | Is genetic testing avaliable for congenital adrenal hyperplasia? Yes, genetic testing is available for many of the genes known to cause congenital adrenal hyperplasia (CAH). Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is congenital adrenal hyperplasia diagnosed? Shortly after birth, all newborns in the United States are screened for a variety of conditions, including 21-hydroxylase deficiency. This is the most common cause of congenital adrenal hyperplasia (CAH) and accounts for 95% of classic CAH cases. Nonclassic CAH is not detected through newborn screening and is often not suspected until signs and symptoms of the condition begin to appear later in childhood or early adulthood. In these cases, a diagnosis of CAH is usually based on physical examination; blood and urine tests that measure hormone levels; and/or genetic testing. An X-ray may also be helpful in confirming the diagnosis in children since CAH can cause bones to grow and develop more quickly than usual (advanced bone age) . |
