What is (are) Werner's syndrome ? | Werner's syndrome is a disease chiefly characterized by premature aging and cancer predisposition. Development is typically normal until the end of the first decade; the first sign is the lack of a growth spurt during puberty. Early signs (usually in the 20s) include loss and graying of hair, hoarseness, and scleroderma-like skin changes, followed by cataracts, type 2 diabetes mellitus, hypogonadism, skin ulcers, and osteoporosis in the 30s. Myocardial infarction (heart attack) and cancer are the most common causes of death, which typically occurs in the late 40s. It is caused by mutations in the WRN gene and is inherited in an autosomal recessive manner. Management focuses on treatment of signs and symptoms and prevention of secondary complications. | |

What is (are) Sideroblastic anemia ? | Sideroblastic anemia is a heterogeneous group of blood disorders characterized by an impaired ability of the bone marrow to produce normal red blood cells. The iron inside red blood cells is inadequately used to make hemoglobin, despite adequate or increased amounts of iron. Abnormal red blood cells called sideroblasts are found in the blood of people with these anemias. Sideroblastic anemias are classified as hereditary, acquired, and reversible. | |
What are the symptoms of Sideroblastic anemia ? | What are the symptoms of sideroblastic anemia? The symptoms of sideroblastic anemia are the same as for any anemia and iron overload. These may include fatigue, weakness, palpitations, shortness of breath, headaches, irritability, and chest pain. Physical findings may include pallor, tachycardia, hepatosplenomegaly, S3 gallop, jugular vein distension, and rales. | |
What causes Sideroblastic anemia ? | What causes sideroblastic anemia? The exact cause of sideroblastic anemia in many patients remains unknown. Reversible sideroblastic anemia can be caused by alcohol, isoniazid, pyrazinamide, cycloserine (a prescription antibiotic that may cause anemia, peripheral neuritis, or seizures by acting as a pyridoxine antagonist or increasing excretion of pyridoxine), chloramphenicol, or copper deficiency. The hereditary forms may be passed through families in autosomal recessive, autosomal dominant, or X-linked patterns. | |
How to diagnose Sideroblastic anemia ? | How is sideroblastic anemia diagnosed? The principle feature of sideroblastic anemia is slowly progressive, mild, life-long anemia which often goes unnoticed. Symptoms of iron overload may lead to the discovery of this underlying disorder. The history and clinical findings, together with laboratory findings, usually permit accurate diagnosis of each type. Laboratory evaluation may include complete blood count, iron studies, free erythrocyte protoporphyrin levels, MRI, bone marrow aspiration and liver biopsy. Molecular defects can be identified in several hereditary forms and in some patients with acquired sideroblastic anemia. | |
What are the treatments for Sideroblastic anemia ? | How might sideroblastic anemia be treated? The treatment of sideroblastic anemia is directed at controlling symptoms of anemia and preventing organ damage from iron overload. Many patients see improvement with increased vitamin B6 intake - either through diet (potatoes, bananas, raisin bran cereal, lentils, liver, turkey, and tuna are good sources) or supplements - with red blood cell counts returning to near-normal values. Folic acid supplementation may also be beneficial. Those that do not respond to vitamin supplementation require blood transfusion. A few small studies have described the use of allogenic bone marrow or stem cell transplantation for hereditary and congenital forms of sideroblastic anemia. While these therapies may offer the possibility of a cure, the complications associated with transplantation surgery must be considered. All patients with sideroblastic anemia should be followed by a hematologist and avoid alcohol. | |
What is (are) Hereditary spherocytosis ? | Hereditary spherocytosis is a condition characterized by hemolytic anemia (when red blood cells are destroyed earlier than normal). Signs and symptoms can range from mild to severe and may include pale skin, fatigue, anemia, jaundice, gallstones, and enlargement of the spleen. Some people with a severe form may have short stature, delayed sexual development, and skeletal abnormalities. The condition is caused by mutations in any of several genes, such as the ANK1, EPB42, SLC4A1, SPTA1, and SPTB genes. It is most commonly inherited in an autosomal dominant manner, but may be inherited in an autosomal recessive manner. There are different types of hereditary spherocytosis, which are distinguished by severity and genetic cause. Depending on severity, treatment may involve splenectomy, red cell transfusions, folic acid supplementation, and/or cholecystectomy. | |

What causes Hereditary spherocytosis ? | What causes hereditary spherocytosis? Hereditary spherocytosis may be caused by mutations in any one of several genes. The mutations that cause the condition result in the formation of spherical, overly rigid, misshapen red blood cells. The misshapen red blood cells, called spherocytes, are removed from circulation and taken to the spleen for destruction. Within the spleen, the red blood cells break down (undergo hemolysis). The shortage of red blood cells in the blood circulation and the abundance of cells in the spleen are responsible for the signs and symptoms of this condition. Mutations in the ANK1 gene are responsible for about half of all cases of hereditary spherocytosis. The other genes associated with hereditary spherocytosis account for a smaller percentage of cases and include the EPB42, SLC4A1, SPTA1, and SPTB genes. | |
Is Hereditary spherocytosis inherited ? | How is hereditary spherocytosis inherited? About 75 percent of cases of hereditary spherocytosis are inherited in an autosomal dominant manner, which means that one copy of the altered (mutated) gene in each cell is sufficient to cause the condition. The mutated gene may be inherited from an affected parent or may occur for the first time in the affected individual. Each child of an individual with an autosomal dominant form of hereditary spherocytosis has a 50% (1 in 2) risk to inherit the mutated gene. Less commonly, hereditary spherocytosis is inherited in an autosomal recessive manner, which means that both copies of the disease-causing gene in each cell have mutations. Parents of a person with an autosomal recessive condition each carry one copy of the mutated gene and are referred to as carriers. Carriers of an autosomal recessive condition typically do not have signs and symptoms of the condition. When two carriers of the same autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have to condition, a 50% (1 in 2) risk to be a carrier like each parent, and a 25% risk to not have the condition and not be a carrier. In some of the cases that result from new mutations in people with no history of the condition in their family, the inheritance pattern may be unclear. | |

What is (are) Type 1 plasminogen deficiency ? | Type 1 plasminogen deficiency is a genetic condition associated with chronic lesions in the pseudomembrane (tough, thick material) of the mucosa of the eye, mouth, nasopharynx, trachea, and female genital tract; decreased serum plasminogen activity; and decreased plasminogen antigen level. The lesions may be triggered by local injury and/or infection and often recur after removal of the lesion; they are caused by the deposition of fibrin (a protein involved in blood clotting) and by inflammation. The most common clinical finding is ligenous ('wood-like') conjunctivitis, a condition marked by redness and subsequent formation of pseudomembranes of part of the eye that progresses to white, yellow-white or red thick masses with a wood-like consistency that replace the normal mucosa. Hydrocephalus may be present at birth in a small number of individuals. | |
What are the symptoms of Type 1 plasminogen deficiency ? | What are the signs and symptoms of Type 1 plasminogen deficiency? Type 1 plasminogen deficiency causes reduced levels of functional plasminogen. The rare inflammatory disease mainly affects the mucous membrances in different body sites. Although the symptoms and their severity may vary from person to person, the most common clinical manifestation is ligneous conjunctivitis, characterized by development of fibrin-rich, woodlike ('ligneous') pseudomembranous lesions. Involvement of the cornea may result in blindness. Other, less common manifestations are ligenous gingivitis, otitis media, ligneous bronchitis and pneumonia, involvement of the gastrointestinal or female genital tract, juvenile colloid milium of the skin (condition in which clear papules develop on sun-exposed areas of the skin), and congenital hydrocephalus. Although the condition is known to cause thrombotic events in mice, no reports of venous thrombosis in humans with the condition have been documented.[826] The Human Phenotype Ontology provides the following list of signs and symptoms for Type 1 plasminogen deficiency.

What causes Type 1 plasminogen deficiency ? | What causes plasminogen deficiency, type 1? Plasminogen deficiency, type 1 is caused by a mutation in a gene encoding plasminogen, an enzyme whose function is to dissolve fibrin clots. Fibrin clots form scabs at a wound site. | |
Is Type 1 plasminogen deficiency inherited ? | Is plasminogen deficiency, type 1 inherited? If so, in what manner? Plasminogen deficiency, type 1 is inherited in an autosomal recessive fashion, which means that an individual must inherit two disease-causing mutated copies of the plasminogen gene in order to have the condition and exhibit symptoms. | |
What are the treatments for Type 1 plasminogen deficiency ? | How might type 1 plasminogen deficiency be treated? The treatment options available for type 1 plasminogen deficiency are few. However, some researchers have shown that the ligneous lesions can be reversed by plasminogen infusion, with changes occurring within 3 days and restored to normal after 2 weeks of treatment. Recurrence has been prevented by daily injections with plasminogen sufficient to achieve plasma concentrations to approximately 40% of the normal amount of plasminogen. Treatment with topical plasminogen has also been successful and resulted in dramatic improvement and complete resolution of the membranes. In some women, treatment with oral contraceptives have resulted in an increase in the levels of plasminogen and some resolution of the pseudomembrane. | |

What is (are) Limited systemic sclerosis ? | Systemic sclerosis ine scleroderma is a type of systemic scleroderma that is characterized by Raynaud's phenomenon and the buildup of scar tissue (fibrosis) on one or more internal organs but not the skin. While the exact cause of sine scleroderma is unknown, it is believed to originate from an autoimmune reaction which leads to the overproduction of collagen (a tough protein which normally strengthens and supports connective tissues throughout the body). When fibrosis affects internal organs, it can lead to impairment or failure of the affected organs. The most commonly affected organs are the esophagus, heart, lungs, and kidneys. Internal organ involvement may be signaled by heartburn, difficulty swallowing (dysphagia), high blood pressure (hypertension), kidney problems, shortness of breath, diarrhea, or impairment of the muscle contractions that move food through the digestive tract (intestinal pseudo-obstruction). | |

What causes Long QT syndrome ? | What causes long QT syndrome? Acquired long QT syndrome can be caused by certain medicines and medical conditions. Some medications that cause long QT syndrome include antihistamines and decongestants, antibiotics, antidepressants, and cholesterol-lowering medicines. Examples of medical conditions that can cause long QT syndrome include excessive diarrhea or vomiting and certain thyroid disorders. Inherited forms of long QT syndrome are caused by changes in genes that control the heart muscles electrical activity. Inherited long QT syndrome may be isolated (occur alone without other associated symptoms) or be due to a genetic syndrome, such as Romano-Ward syndrome, Jervell Lang-Nielsen syndrome, Anderson-Tawil syndrome, and Timothy syndrome. | |
How to diagnose Long QT syndrome ? | How is long QT syndrome diagnosed? Long QT syndrome is diagnosed on the basis of electrocardiographic (EKG) findings, clinical findings such as congenital deafness or unexplained fainting, and family history of long QT syndrome or sudden cardiac death. Genetic testing is often performed in families in whom the diagnosis of long QT syndrome has been made or is suspected on clinical grounds. | |

The Human Phenotype Ontology provides the following list of signs and symptoms for Leber congenital amaurosis 10. 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) Seizures 2/4 Autosomal recessive inheritance - Hyposmia - Visual impairment - 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. | |
What is (are) Ankylosing spondylitis ? | Ankylosing spondylitis (AS) is a type of chronic, inflammatory arthritis that mainly affects the spine. It usually begins with inflammation of the joints between the pelvic bones and spine, gradually spreading to the joints between the vertebrae. Signs and symptoms usually begin in adolescence or early adulthood and may include back pain and stiffness. Back movement gradually becomes more limited as the vertebrae fuse together. The condition may also affect the shoulders; ribs; hips; knees; and feet; as well as the eyes; bowel; and very rarely, the heart and lungs. AS is likely caused by a combination of genetic and environmental factors; variations in several genes are thought to affect the risk to develop AS. In most cases, treatment involves exercise and medications to relieve pain and inflammation. | |
What are the symptoms of Ankylosing spondylitis ? | What are the signs and symptoms of Ankylosing spondylitis? Ankylosing spondylitis (AS) primarily affects the spine, but may affect other parts of the body too. Signs and symptoms usually begin in adolescence or early adulthood and include back pain and stiffness. Back movement gradually becomes more limited over time as the vertebrae fuse together. Many affected people have mild back pain that comes and goes; others have severe, chronic pain. In very severe cases, the rib cage may become stiffened, making it difficult to breathe deeply. In some people, the condition involves other areas of the body, such as the shoulders, hips, knees, and/or the small joints of the hands and feet. It may affect various places where tendons and ligaments attach to the bones. Sometimes it can affect other organs including the eyes, and very rarely, the heart and lungs. Episodes of eye inflammation may cause eye pain and increased sensitivity to light (photophobia). Neurological complications of AS may include an inability to control urination and bowel movements (incontinence), and the absence of normal reflexes in the ankles due to pressure on the lower portion of the spinal cord (cauda equina). The Human Phenotype Ontology provides the following list of signs and symptoms for Ankylosing spondylitis.

Is Ankylosing spondylitis inherited ? | Is ankylosing spondylitis inherited? Although ankylosing spondylitis (AS) can affect more than one person in a family, it is not a purely genetic disease. While genes seem to play a role, the exact cause of AS is not known. It is considered to be multifactorial, which means that multiple genetic and environmental factors likely interact to affect a person's risk to develop AS. Most of these factors have not been identified. Inheriting a genetic variation that has been associated with AS does not mean a person will develop AS. Currently, it is not possible to predict the exact likelihood that the children of an affected person will develop the disease. You can find more information about the genetics of AS from Genetics Home Reference, the U.S National Library of Medicine's Web site for consumer information about genetic conditions and the genes or chromosomes related to those conditions. | |
What are the treatments for Ankylosing spondylitis ? | How might ankylosing spondylitis be treated? The main goal of treatment for people with ankylosing spondylitis (AS) is to maximize long-term quality of life. This may involve easing symptoms of pain and stiffness; retaining function; preventing complications (such as contractures); and minimizing the effects of associated conditions. Education, exercise, and medications are all very important in managing AS. An exercise program is recommended for all affected people, and some may need individual physical therapy. Affected people are encouraged to speak with their health care provider before instituting any changes to an exercise regime. Video demonstrations of exercises tailored for ankylosing spondylitis are available for viewing through the National Ankylosing Spondylitis Society in the UK. Medications may include nonsteroidal anti-inflammatory drugs (NSAIDs); pain relievers; sulfasalazine; and anti-tumor necrosis factor drugs. Steroid injections may be helpful for some people. Most people don't need surgery, but it may be indicated when there is severe, persistent pain or severe limitation in mobility and quality of life. Smoking creates additional problems for people with AS, so affected people who smoke should quit. More detailed information about the treatment of ankylosing spondylitis is available on Medscape's Web site. You may need to register to view the article, but registration is free. | |

What is (are) Richter syndrome ? | Richter syndrome is a rare condition in which chronic lymphocytic leukemia (CLL) changes into a fast-growing type of lymphoma. Symptoms of Richter syndrome can include fever, loss of weight and muscle mass, abdominal pain, and enlargement of the lymph nodes, liver, and spleen. Laboratory results may show anemia and low platelet counts (which can lead to easy bleeding and bruising). | |
What are the treatments for Richter syndrome ? | Are there any recent advancements in the treatment of Richter syndrome? Monoclonal antibodies (MABs) are a type of biological therapy. They are man-made proteins that target specific proteins on cancer cells. MABs are a fairly new treatment for cancer. Doctors often use the MAB drug called rituximab along with chemotherapy and steroids to treat Richter syndrome. Researchers in a trial called the CHOP-OR study are studying whether a new biological therapy similar to rituximab can make CHOP chemotherapy work better. The new biological therapy drug is called ofatumumab (Arzerra). People who have been recently diagnosed with Richter syndrome can participate in this study. The study has two parts. First, patients have ofatumumab with CHOP chemotherapy to eliminate the lymphoma (this is called induction treatment). They then have more ofatumumab on its own to try to stop the lymphoma from coming back (this is called maintenance treatment). CLICK HERE to learn more about this study. Stem cell transplant is another way of treating Richter syndrome. While only a few people have undergone stem cell transplant for treatment of this disease, so far it has appeared to work quite well. The disease was controlled for longer than in people having normal dose chemotherapy. However, because stem cell transplants have serious side effects and complications, they are only suitable for a small group of people. More research is needed before we can truly find out how well stem cell treatment works for people with Richter syndrome. A recent study showed that a chemotherapy regimen called OFAR (a combination of oxaliplatin, fludarabine, cytarabine, and rituximab) had significant antileukemic activity in patients with Richter syndrome and relapsed/refractory CLL. Patients who underwent stem cell therapy as post-remission therapy had even more favorable outcomes. | |
What is (are) Distal chromosome 18q deletion syndrome ? | Distal chromosome 18q deletion syndrome is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material at the end of the long arm (q) of chromosome 18. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with distal chromosome 18q deletion syndrome include developmental delay, intellectual disability, behavioral problems and distinctive facial features. Chromosome testing of both parents can provide more information on whether or not the deletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent is found to have a balanced translocation, where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a deletion. Treatment is based on the signs and symptoms present in each person. This page is meant to provide general information about distal 18q deletions. You can contact GARD if you have questions about a specific deletion on chromosome 18. To learn more about chromosomal anomalies please visit our GARD webpage on FAQs about Chromosome Disorders. | |

What is (are) Ehlers-Danlos syndrome, progeroid type ? | Ehlers-Danlos syndrome progeroid type is a genetic disorder of the connective tissue, which is the material between the cells of the body that gives tissues form and strength. The disorder primarily affects the skin, hair, and skeletal system. Symptoms usually show up by childhood or adolescence. Like people with other types of Ehlers-Danlos syndrome, individuals with the progeroid form have unusually flexible joints, loose elastic skin, and easy scarring. Features that are unique to this type include sparse scalp hair and eyebrows, and loose elastic skin on the face; these features cause affected individuals to look older than their age. Additional symptoms may include bone weakness, weak muscle tone, mild intellectual disability, and delayed growth in affected children. The progeroid type of Ehlers-Danlos syndrome is caused by mutations in the B4GALT7 gene and is inherited in an autosomal recessive pattern. | |
What are the symptoms of Ehlers-Danlos syndrome, progeroid type ? | What are the signs and symptoms of Ehlers-Danlos syndrome, progeroid type? Ehlers-Danlos syndrome refers to a group of connective tissue disorders characterized by stretchy or kneadable skin, double jointedness, and delayed healing of skin wounds. In addition to these traits, individuals with the progeroid type have thin curly hair, sparse eyebrows and eyelashes, loose elastic skin on the face, and may also have uneven facial features. Although progeroid means "appearance similar to old age", individuals with progeroid Ehlers-Danlos syndrome do not actually have premature aging and are not expected to have a shortened life span. Other symptoms may include poor muscle tone, fragile bones from low bone mineral density, abnormal teeth, and infection of gums around the teeth. Children who are affected may have delayed growth, which can result in short stature as an adult (less than 152cm). Mild intellectual disabilities or learning disabilities have also been associated with this disorder. The Human Phenotype Ontology provides the following list of signs and symptoms for Ehlers-Danlos syndrome, progeroid type. 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.

What causes Ehlers-Danlos syndrome, progeroid type ? | What causes Ehlers-Danlos syndrome progeroid type? Ehlers-Danlos syndrome progeroid type is caused by changes (mutations) in both of an individual's copies of the B4GALT7 gene, which is located on chromosome 5. This gene provides instructions for making an enzyme that is involved in the production of collagen (the main protein in connective tissue). When not enough enzyme is made by the B4GALT7 genes, collagen is not formed correctly in connective tissue. The symptoms of the disorder are caused by weak connective tissue. Researchers are still studying exactly how mutations in the B4GALT7 gene cause the signs and symptoms of Ehlers-Danlos syndrome progeroid type. | |
Is Ehlers-Danlos syndrome, progeroid type inherited ? | How is Ehlers-Danlos syndrome progeroid type inherited? Ehlers-Danlos syndrome progeroid type is inherited in an autosomal recessive pattern. This means that an individual must have two non-functional copies of the B4GALT7 gene to be affected with the condition. One copy is inherited from each parent. If an individual has only one non-functional B4GALT7 gene (such as each parent), he or she is a "carrier". Carriers do not typically show any signs or symptoms of a recessive condition. When two carriers for a recessive condition have children, with each pregnancy there is a 25% (1 in 4) risk for the child to be affected, a 50% (1 in 2) risk for the child to be a carrier (like each parent) and a 25% risk that the child will be unaffected and also not be a carrier. An individual with a recessive condition will generally have unaffected children, except in the rare circumstance where his or her partner is a carrier of a nonfunctional B4GALT7 gene. | |
What are the treatments for Ehlers-Danlos syndrome, progeroid type ? | How might Ehlers-Danlos syndrome progeroid type be treated? Individuals with Ehlers-Danlos Syndrome progeroid type can benefit from a variety of treatments depending on their symptoms. Affected children with weak muscle tone and delayed development might benefit from physiotherapy to improve muscle strength and coordination. Affected individuals with joint pain might benefit from anti-inflammatory drugs. Lifestyle changes or precautions during exercise or intense physical activity may be advised to reduce the chance of accidents to the skin and bone. It is recommended that affected individuals discuss treatment options with their healthcare provider. | |
What is (are) Hypoplastic right heart syndrome ? | Hypoplastic right heart syndrome is a rare heart defect, present at birth (congenital), that results in low blood oxygen levels. It is caused by underdevelopment of the structures on the right side of the heart (tricuspid valve, right ventricle, pulmonary valve, and pulmonary artery) and commonly associated with atrial septal defect. The underdeveloped right side of the heart is unable to provide enough blood flow to the body, leading to low blood oxygen and cyanosis. It differs from hypoplastic left heart syndrome which involves the underdevelopment of the structures on the left side of the heart. | |

What is (are) Neuroblastoma ? | Neuroblastoma is a tumor that develops from a nerve in a child, usually before the age of 5. It occurs in the abdomen near the adrenal glands, but it can also occur in other parts of the body. It is considered an aggressive tumor because it often spreads to other parts of the body (metastasizes). The symptoms of a neuroblastoma may include a lump in the abdomen, pain, diarrhea, or generally feeling unwell. It affects one out of 100,000 children. The exact cause of this tumor is not yet known. Neuroblastoma may be diagnosed by physical examination; specific blood tests; imaging tests such as x-rays, magnetic resonance imaging (MRI), or computed tomography (CT) scans; and a biopsy. Treatment depends on the size and location of the tumor within the body, as well as the childs age. Surgery is often the first step of treatment, and may be followed by chemotherapy, radiation therapy, or a stem cell transplant in more severe cases. | |

What is (are) Portal hypertension ? | Portal hypertension is abnormally high blood pressure in branches of the portal vein, the large vein that brings blood from the intestine to the liver. Portal hypertension itself does not cause symptoms, but complications from the condition can lead to an enlarged abdomen, abdominal discomfort, confusion, drowsiness and internal bleeding. It may be caused by a variety of conditions, but cirrhosis is the most common cause in Western countries. Treatment is generally directed toward the cause of the condition, although emergency treatment is sometimes needed for serious complications. | |

What is (are) L-2-hydroxyglutaric aciduria ? | L-2-hydroxyglutaric aciduria is an inherited metabolic condition that is associated with progressive brain damage. Signs and symptoms of this condition typically begin during infancy or early childhood and may include developmental delay, seizures, speech difficulties, macrocephaly and abnormalities in a part of the brain called the cerebellum, which is involved in coordinating movement (i.e. balance and muscle coordination). L-2-hydroxyglutaric aciduria is caused by changes (mutations) in the L2HGDH gene and is inherited in an autosomal recessive manner. Treatment is focused on alleviating the signs and symptoms of the condition, such as medications to control seizures. | |

What is (are) Chromosome 15q deletion ? | Chromosome 15q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 15. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 15q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. 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 is (are) Macular degeneration ? | Age-related macular degeneration (AMD) is an eye condition characterized by progressive destruction of the macula. The macula is located in the retina in the eye and enables one to see fine details and perform tasks that require central vision, such as reading and driving. Signs and symptoms include vision loss, which usually becomes noticeable in a person's sixties or seventies and tends to worsen over time. There are 2 major types of AMD, known as the dry form and the wet form. The dry form accounts for up to 90% of cases and is characterized by slowly progressive vision loss. The wet form is associated with severe vision loss that can worsen rapidly. AMD is caused by a combination of genetic and environmental factors, some of which have been identified. Increasing age is the most important non-genetic risk factor. The condition appears to run in families in some cases. While there is currently no cure for AMD, there are therapies available to help slow the progression of the condition. | |

What is (are) L1 syndrome ? | L1 syndrome is a mild to severe congenital disorder with hydrocephalus of varying degrees of severity, intellectual disability, spasticity of the legs, and adducted thumbs. It includes several conditions, some more severe than others: X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS) - the most severe of all; MASA syndrome (intellectual disability, aphasia (delayed speech), spastic paraplegia (shuffling gait), adducted thumbs); SPG1 (X-linked complicated hereditary spastic paraplegia type 1) X-linked complicated corpus callosum agenesis. It is inherited in an X-linked manner; therefore, it only affects males. It is caused by alterations (mutations) in L1CAM gene. The diagnosis is made in males who have the clinical and neurologic findings and a family history consistent with X-linked inheritance and is confirmed by a genetic test showing the L1CAM gene mutation. The treatment involves doing a surgery for the hydrocephalus. | |

What is (are) Restless legs syndrome ? | Restless legs syndrome is a neurological condition that causes an irresistible urge to move the legs. The movement is triggered by strange or uncomfortable feelings, which occur mostly while the affected person is sitting or lying down and are worse at night. Movement (i.e. kicking, stretching, rubbing, or pacing) makes the discomfort go away, at least temporarily. Many people with restless legs syndrome also experience uncontrollable, repetitive leg movements that occur while they are sleeping or while relaxed or drowsy. Researchers have described early-onset and late-onset forms of restless legs syndrome. The early-onset form begins before age 45 and progresses slowly. The late-onset form begins after age 45, and its signs and symptoms tend to worsen more rapidly. Restless legs syndrome likely results from a combination of genetic, environmental, and lifestyle factors, many of which are unknown. Treatment is based on the signs and symptoms present in each person. | |
What is (are) Acute intermittent porphyria ? | Acute intermittent porphyria (AIP) is one of the liver (hepatic) porphyrias. AIP is caused by low levels of porphobilinogen deaminase (PBGD), an enzyme also often called hydroxymethylbilane synthase. The low levels of PBGD are generally not sufficient to cause symptoms; however, activating factors such as hormones, drugs, and dietary changes may trigger symptoms. Although most individuals with AIP never develop symptoms, symptomatic individuals typically present with abdominal pain with nausea. Treatment is dependent on the symptoms. | |
What are the symptoms of Acute intermittent porphyria ? | What are the signs and symptoms of Acute intermittent porphyria? Some people who inherit the gene for AIP never develop symptoms and are said to have "latent" AIP. Those individuals that present with symptoms usually do so after puberty, probably because of hormonal influences, although other activating factors include: alcohol, drugs (e.g., barbiturates, steroids, sulfa-containing antibiotics), chemicals, smoking, reduced caloric intake, stress, and travel. Symptoms usually last several days, but attacks for which treatment is not received promptly may last weeks or months. Abdominal pain, which is associated with nausea and can be severe, is the most common symptom and usually the first sign of an attack. Other symptoms may include : Gastrointestinal issues (e.g., nausea, vomiting, constipation, diarrhea, abdominal distention, ileus) Urinary tract issues (e.g., urinary retention, urinary incontinence, or dysuria) Neurological issues (e.g., muscle weakness in the arms or legs, paralysis) Psychiatric issues (e.g., insomnia, hysteria, anxiety, apathy or depression, phobias, psychosis, agitation, delirium, somnolence, or coma) Individuals with AIP have an increased risk of developing hepatocellular carcinoma; some develop kidney failure.

What causes Acute intermittent porphyria ? | What causes acute intermittent porphyria (AIP)? AIP is caused by the deficiency of an enzyme called porphobilinogen deaminase (PBGD), also known as hydroxymethylbilane synthase (HMBS) and formerly known as uroporphyrinogen I-synthase. The deficiency of PBGD is caused by a mutation in the HMBS gene. The HMBS gene is the only gene known to be associated with AIP. However, the deficiency of PBGD alone is not enough to cause AIP. Other activating factors (e.g., hormones, drugs, dietary changes) must also be present. | |
Is Acute intermittent porphyria inherited ? | How is acute intermittent porphyria (AIP) inherited? AIP is inherited in an autosomal dominant fashion, which means only one of the two HMBS genes needs to have a disease-causing mutation to decrease enzyme activity and cause symptoms. | |
How to diagnose Acute intermittent porphyria ? | How is acute intermittent porphyria (AIP) diagnosed? Diagnosis of AIP is suspected in individuals with otherwise unexplained severe, acute abdominal pain without physical signs. The finding of increased levels of delta-aminolevulinic acid (ALA) and porphobilinogen (PBG) in urine establishes that one of the acute porphyrias is present. If PBGD is deficient in normal red blod cells, the diagnosis of AIP is established. The diagnosis is confirmed in individuals with a disease-causing mutation in the HMBS gene, the only gene known to be associated with AIP, which encodes the erythrocyte hydroxymethylbilane synthase enzyme. Molecular genetic testing of the HMBS gene detects more than 98% of affected individuals and is available in clinical laboratories. To obtain a list of clinical laboratories offering genetic testing for AIP, click here. | |
What are the treatments for Acute intermittent porphyria ? | How might acute intermittent porphyria (AIP) be treated? Treatment of AIP may vary based on the trigger of the attack and the symptoms present. Treatment may include stopping medications that cause or worsen the symptoms, treating any infections which may be present, administration of pain medication, monitoring fluid balance and/or correcting electrolyte disturbances, monitoring neurologic status and administering respiratory support. Mild attacks can be manged with increased caloric intake and fluid replacement. Recurrent acute attacks should be managed by a porphyria specialist. Hospitalization is often necessary. Panhematin, an intravenous medication used to correct heme deficiency, may also be prescribed. More detailed information about the use of Panhematin for the treatment of AIP can be found by clicking here. | |
What is (are) Pili torti ? | Pili torti is a rare hair condition characterized by fragile hair. In pili torti hair has a flattened shaft with clusters of narrow twists at irregular intervals. Some cases may be inherited in autosomal dominant or autosomal recessive patterns, while others are acquired. In the inherited form, symptoms tend to be present from early childhood. It can occur alone or as part of other diseases like ectodermal dysplasias, Menke disease, Bjornstand syndrome, or Bazex syndrome. Acquired cases of pili torti may be associated with anorexia nervosa, malnutrition, oral retinoid treatment, or inflammatory scalp conditions (e.g., cutaneous lupus erythematousus). If pili torti is detected, it is necessary to investigate possible neurological disorders, hearing loss, and defects in the hair, nails, sweat glands and teeth. There is no specific treatment for this condition, but it may improve spontaneously after puberty. Click here to visit Medscape and view an image of a child with pili torti. | |

What are the treatments for Pili torti ? | Are there new therapies for treatment of pili torti? In acquired pili torti, treatment involves stopping the exposure to the causative agent (e.g., to oral retinoids) or condition (e.g., improving diet). There is no specific treatment for the inherited form of pili torti. It may improve spontaneously after puberty. If pili torti is detected, further evaluation to investigate possible neurological disorders, problems with hair, teeth or nails (ectodermal disturbances) and hearing loss is mandatory. It is generally recommended that people with pili torti try to avoid trauma to the hair. Suggestions include, sleeping on a satin pillowcase, avoiding excessive grooming, braiding, heat treatments, dying and coloring, reducing exposure to sunlight (wear a hat), using gentle shampoos diluted in warm water, adding conditioner to freshly washed hair, avoiding use of a hair dryer (or using it on cool setting), and avoiding oral retinoids (e.g., isotretinoin, acitretin) if possible. Some individuals with pili torti choose to wear a wig. | |
What is (are) Severe combined immunodeficiency ? | Severe combined immunodeficiencies (SCID) are inherited immune system disorders characterized by abnormalities with responses of both T cells and B cells (specific types of white blood cells needed for immune system function). Common signs and symptoms include an increased susceptibility to infections including ear infections; pneumonia or bronchitis; oral thrush; and diarrhea. Due to recurrent infections, affected children do not grow and gain weight as expected (failure to thrive). SCID may be caused by mutations in any of several genes and can be inherited in an X-linked recessive (most commonly) or autosomal recessive manner. The most effective treatment is transplantation of blood-forming stem cells from the bone marrow of a healthy person. Without treatment, affected children rarely live past the age of two. | |
Is Severe combined immunodeficiency inherited ? | How is severe combined immunodeficiency inherited? Severe combined immunodeficiency (SCID) can be inherited in an X-linked recessive or autosomal recessive manner depending on the genetic cause of the condition. X-linked SCID is the most common type of SCID and is inherited in an X-linked recessive manner. A condition is X-linked if the changed (mutated) gene responsible for the condition is located on the X chromosome. The X chromosome is one of the two sex chromosomes; females have two X chromosomes and males have one X chromosome and one Y chromosome. In males, one mutated copy of the responsible gene causes signs and symptoms of the condition because they don't have another X chromosome with a working copy of the gene. In females, having one mutated copy of the gene would make them an unaffected carrier; a mutation would have to occur in both copies of the gene to cause the condition. This is why X-linked recessive disorders, including X-linked SCID, occur much more frequently in males. Because fathers only pass their Y chromosome on to their sons, fathers cannot pass X-linked conditions on to their sons. The other, less common causes of SCID are inherited in an autosomal recessive manner. These types are due to mutations in responsible genes on other chromosomes (not the sex chromosomes). In autosomal recessive conditions, a person must have mutations in both copies of the responsible gene in order to have signs or symptoms of the condition. In most cases, the affected person inherits one mutated copy of the gene from each of the parents, who are typically unaffected carriers. | |
How to diagnose Severe combined immunodeficiency ? | How is severe combined immunodeficiency (SCID) diagnosed? A diagnosis of severe combined immunodeficiency (SCID) may be suspected if a baby shows any of the following persistent symptoms within the first year of life: Eight or more ear infections Two or more cases of pneumonia Infections that do not resolve with antibiotic treatment for two or more months Failure to gain weight or grow normally Infections that require intravenous antibiotic treatment Deep-seated infections, such as pneumonia that affects an entire lung or an abscess in the liver Persistent thrush in the mouth or throat A family history of immune deficiency or infant deaths due to infections Diagnosis can be confirmed by blood tests. Blood tests show significantly lower-than-normal levels of T cells and antibodies.

What is (are) Multiple familial trichoepithelioma ? | Multiple familial trichoepithelioma is a rare condition characterized by multiple smooth, round, firm, skin-colored tumors (trichoepitheliomas) that usually occur on the face, but may also occur on the scalp, neck, and trunk. The tumors are derived from immature hair follicles. They usually first develop during childhood or adolescence and may grow larger and increase in number over time. The condition can be caused by alterations (mutations) in the CYLD gene or by mutations in other genes which are still unknown. The condition may be divided in two subtypes, multiple familial trichoepithelioma type 1 and multiple familial trichoepithelioma type 2. Susceptibility to multiple familial trichoepithelioma is inherited in an autosomal dominant fashion, which means one copy of the altered gene in each cell increases the risk of developing this condition. However, a second, non-inherited mutation is required for development of skin appendage tumors in this disorder.Treatment often involves surgery to remove a single lesion and cryosurgery or laser surgery for multiple ones. | |
What are the symptoms of Multiple familial trichoepithelioma ? | What are the signs and symptoms of Multiple familial trichoepithelioma? People with multiple familial trichoepithelioma typically develop large large numbers of smooth, round, firm skin-colored tumors called trichoepitheliomas, which arise from hair follicles. These benign (noncancerous) tumors may occasionally transform into a type of skin cancer called basal cell carcinoma. Occasionally, other types of tumors, including growths called spiradenomas (which originate in sweat glands) and cylindromas (which likely originate in hair follicles) also develop. Affected individuals are also at-risk to develop tumors in other tissues, particularly benign tumors of the salivary glands. The tumors in multiple familial trichoepithelioma typically first appear during childhood or adolescence, and appear most often around the nose, forehead, upper lip, and occasionally scalp, neck, and upper trunk. They may grow larger and increase in number over time. In rare cases, the tumors may get in the way of the eyes, ears, nose, or mouth and affect vision or hearing. The growths can be disfiguring and may contribute to depression or other psychological problems. For reasons that remain unknown, females are often more severely affected than males. The Human Phenotype Ontology provides the following list of signs and symptoms for Multiple familial trichoepithelioma. 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.

What causes Multiple familial trichoepithelioma ? | What causes multiple familial trichoepithelioma? Multiple familial trichoepithelioma is thought to be inherited in an autosomal dominant fashion with reduced penetrance. Autosomal dominant means that a single mutation in one copy of a gene is sufficient to cause the condition. Reduced penetrance means that not everyone with the gene mutation will develop symptoms of the condition. Multiple familial trichoepithelioma can be caused by mutations in the CYLD gene which is found on chromosome 16 or by a mutation on a gene on chromsome 9 that has yet to be identified. | |
Is Multiple familial trichoepithelioma inherited ? | How is multiple familial trichoepithelioma inherited? Susceptibility to multiple familial trichoepithelioma has an autosomal dominant pattern of inheritance. This means that one copy of the altered gene in each cell increases the risk that a person will develop the condition. However, a second, non-inherited mutation is needed for development of the skin tumors characteristic of this condition. | |
How to diagnose Multiple familial trichoepithelioma ? | How is multiple familial trichoepithelioma diagnosed? Diagnosis of multiple familial trichoepithelioma is made based upon the clinical symptoms in the patient, the patients family history, and the appearance of the trichoepithelioma cells under a microscope (histology). Multiple familial trichoepithelioma must be distinguished from basal cell carcinoma (cancerous tumor) and other rare genetic syndromes such as Cowden syndrome. | |
What are the treatments for Multiple familial trichoepithelioma ? | How might multiple familial trichoepithelioma be treated? Several therapies have been used to treat multiple trichoepitheliomas, with variable results. A single trichoepithelioma may be treated with surgery. Cryosurgery or laser surgery may be used to remove multiple trichoepitheliomas. Imiquimod cream has also been used as a treatment for trichoepitheliomas, with some improvement in symptoms. Other treatments have included dermabrasion, photodynamic therapy, and other medications. However, in most cases, multiple trichoepitheliomas eventually regrow following treatment. | |
What is (are) Familial avascular necrosis of the femoral head ? | Avascular necrosis of the femoral head (ANFH) is a degenerative condition which causes the upper ends of the thigh bones (femurs) to break down due to an inadequate blood supply and deficient bone repair. It can lead to pain and limping and cause the legs to be of unequal length. The prevalence of ANFH is unknown but around 15,000 cases are reported each year in the United States, with most cases being associated with mechanical disruption (hip trauma or surgery), hypofibrinolysis (a reduced ability to dissolve clots), steroid use, smoking, alcohol intake, hemoglobinopathies and hyperlipidemia (an increase in the amount of fat - such as cholesterol and triglycerides - in the blood). Familial forms of ANFH appear to be very rare, with only a few families reported in the medical literature. Age of onset in these familial cases ranges from 15-48 years (as opposed to between 3rd to 5th decade of life for other forms of ANFH). Transmission in familial cases is autosomal dominant and mutations in the type II collagen gene (COL2A1) have been detected in affected family members. | |

What is (are) Paroxysmal nocturnal hemoglobinuria ? | Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired disorder that leads to the premature death and impaired production of blood cells. It can occur at any age, but is usually diagnosed in young adulthood. People with PNH have recurring episodes of symptoms due to hemolysis, which may be triggered by stresses on the body such as infections or physical exertion. This results in a deficiency of various types of blood cells and can cause signs and symptoms such as fatigue, weakness, abnormally pale skin (pallor), shortness of breath, and an increased heart rate. People with PNH may also be prone to infections and abnormal blood clotting (thrombosis) or hemorrhage, and are at increased risk of developing leukemia. It is caused by acquired, rather than inherited, mutations in the PIGA gene; the condition is not passed down to children of affected individuals. Sometimes, people who have been treated for aplastic anemia may develop PNH. The treatment of PNH is largely based on symptoms; stem cell transplantation is typically reserved for severe cases of PNH with aplastic anemia or those whose develop leukemia. | |
