Is Congenital bilateral absence of the vas deferens inherited ? | How is congenital bilateral absence of the vas deferens (CBAVD) inherited? When this condition is caused by mutations in the CFTR gene, it is inherited in an autosomal recessive pattern. This pattern of inheritance means that both copies of the gene in each cell have a mutation. Parents of a person with CBAVD each carry one CFTR mutation, but are usually unaffected (carriers). Men with CBAVD who choose to father children through assisted reproduction have an increased risk of having a child with cystic fibrosis. If congenital absence of the vas deferens is not caused by mutations in CFTR, the risk of having children with cystic fibrosis is not increased. The risk to siblings of a person with CBAVD depends on the affected person's CFTR gene mutation(s) and cannot readily be predicted without this information. Genetic testing is most informative when the CBAVD-causing mutations have been identified in the affected individual. Men with CBAVD sometimes have only one identifiable CFTR mutation, complicating the testing and interpretation of results in their family members. We recommend speaking with a genetics professional about risk to other family members as well as any appropriate genetic testing. | |

What is (are) Guanidinoacetate methyltransferase deficiency ? | Guanidinoacetate methyltransferase deficiency is an inherited condition that affects the brain and muscles. Affected people may begin showing symptoms of the condition from early infancy to age three. Signs and symptoms can vary but may include mild to severe intellectual disability, epilepsy, speech development limited to a few words, behavioral problems (i.e. hyperactivity, autistic behaviors, self-mutilation), and involuntary movements. Guanidinoacetate methyltransferase deficiency is caused by changes (mutations) in the GAMT gene and is inherited in an autosomal recessive manner. Treatment aims to increase the levels of creatine in the brain through supplementation with high doses of oral creatine monohydrate. | |

What is (are) Pectus carinatum ? | Pectus carinatum refers to a chest wall abnormality in which the breastbone is pushed outward. It generally presents during childhood and worsens through adolescence. If the condition occurs in isolation, it is often not associated with any additional signs or symptoms. Rarely, affected people report shortness of breath during exercise, frequent respiratory infections, and/or asthma. The underlying cause of isolated pectus carinatum is unknown. Pectus carinatum can also be associated with a variety of genetic disorders and syndromes, including Marfan syndrome, Noonan syndrome, Morquio syndrome, homocystinuria, osteogenesis imperfecta, Coffin-Lowery syndrome, cardiofaciocutaneous syndrome, and certain chromosome abnormalities. In these cases, the condition has an underlying genetic cause and is associated with additional features that are characteristic of the genetic disease. Pectus carinatum is primarily a cosmetic concern and treatment, therefore, depends on the severity of the condition and the interests of the affected person and their family. In those who choose to pursue treatment, bracing and/or surgery may be an option. | |

What is (are) Long QT syndrome 8 ? | Timothy syndrome is a type of long QT syndrome. It affects many parts of the body including the heart, fingers, toes, face, and the nervous system. It is characterized by long QT syndrome, although some people with Timothy syndrome also have other heart defects that affect the hearts ability to pump blood effectively. Other symptoms of Timothy syndrome include fusion of the skin between fingers or toes and distinctive facial features. In addition, many children with this syndrome have developmental delay and characteristic features of autism. Mental retardation and seizures can also occur in children with Timothy syndrome. There are two forms of Timothy syndrome. Type 1 includes all of the characteristic features described. Type 2 causes a more severe form of long QT syndrome and does not appear to cause fusion of skin between fingers or toes. All cases of Timothy syndrome appear to be due to changes in the CACNA1C gene. This syndrome is inherited in an autosomal dominant manner. However, most cases are not inherited from an affected parent, but occur for the first time in a family due to a spontaneous or random change in the CACNA1C gene. | |

What is (are) Hyperparathyroidism-jaw tumor syndrome ? | Hyperparathyroidism-jaw tumor syndrome is an inherited condition characterized by overactivity of the parathyroid glands (hyperparathyroidism), which regulate the body's use of calcium. In people with this condition, hyperparathyroidism is caused by benign tumors (adenomas) that form in the parathyroid glands. About 15 percent of people with this condition develop a cancerous tumor called parathyroid carcinoma. About 25 to 50 percent of affected individuals can also develop a benign tumor called a fibroma in the jaw. Other benign or cancerous tumors can also develop, including tumors of the uterus in women; benign kidney cysts; and rarely, Wilms tumor. This condition is caused by mutations in the CDC73 gene and is inherited in an autosomal dominant fashion. | |

What is (are) Tracheobronchomalacia ? | Tracheobronchomalacia (TBM) is a rare condition that occurs when the walls of the airway (specifically the trachea and bronchi) are weak. This can cause the airway to become narrow or collapse. There are two forms of TBM: a congenital form (called primary TBM) that typically develops during infancy or early childhood and an acquired form (called secondary TBM) that is usually seen in adults. Some affected people may initially have no signs or symptoms. However, the condition is typically progressive (becomes worse overtime) and most people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Most cases of primary TBM are caused by genetic conditions that weaken the walls of the airway, while the secondary form often occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways. Treatment is generally only required in those who have signs and symptoms of the condition and may include stenting, surgical correction, continuous positive airway pressure (CPAP), and tracheostomy. | |

However, the condition is typically progressive (becomes worse overtime) and many people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Symptoms may become worse during periods of stress (i.e. illness), when reclining, or when forcing a cough. Infants and young children with TBM tend to have more frequent respiratory infections and delayed recovery from these illnesses. | |
What causes Tracheobronchomalacia ? | What causes tracheobronchomalacia? The underlying cause of tracheobronchomalacia (TBM) varies by subtype. Most cases of primary TBM (also called congenital TBM) are caused by genetic conditions that weaken the walls of the airway (specifically the trachea and bronchi). For example, TBM has been reported in people with mucopolysaccharidoses (such as Hunter syndrome and Hurler syndrome), Ehlers-Danlos Syndrome, and a variety of chromosome abnormalities. Primary TBM can also be idiopathic (unknown cause) or associated with prematurity and certain birth defects (i.e. tracheoesophageal fistula). The secondary form (also called acquired TBM) is caused by the degeneration (break down) of cartilage that typically supports the airways. It is most commonly associated with: Certain medical procedures such as endotracheal intubation or tracheostomy Conditions that lead to chronic (persisting or progressing for a long period of time) inflammation such as relapsing polychondritis or chronic obstructive pulmonary disease (COPD) Cancers, tumors, or cysts that cause prolonged compression of the airway | |
Is Tracheobronchomalacia inherited ? | Is tracheobronchomalacia inherited? Primary tracheobronchomalacia (TBM) is often associated with certain genetic conditions. In some cases, an affected person inherits the condition from an affected parent. Other cases may result from new (de novo) gene mutations. These cases occur in people with no history of the disorder in their family. When TBM is part of a genetic condition, it can be passed on to future generations. Secondary TBM (also called acquired TBM) is not inherited. It generally occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways. | |
How to diagnose Tracheobronchomalacia ? | How is tracheobronchomalacia diagnosed? A diagnosis of tracheobronchomalacia (TBM) may be suspected based on the presence of characteristic signs and symptoms or abnormal pulmonary function tests. Additional testing such as CT scan and bronchoscopy can then be performed to confirm the diagnosis and evaluate the severity of the condition. TBM is considered mild if the trachea narrows to 50% of its initial size while the affected person is breathing out, moderate if it narrows to 25%, and severe if the walls of the trachea touch. | |
What are the treatments for Tracheobronchomalacia ? | How might tracheobronchomalacia be treated? Treatment is only medically necessary in people who have signs and symptoms of tracheobronchomalacia (TBM). Management of symptomatic TBM first involves identifying underlying conditions contributing to symptoms, such as chronic inflammation, compression, or injury. Initial treatment will target these underlying medical concerns. If symptoms persist, people with TBM may undergo pulmonary function tests or other assessments to help guide therapy choice and allow monitoring of the response to treatment. Treatment options may include: Silicone and/or long-term stenting Surgical correction Continuous positive airway pressure (CPAP) Tracheostomy (often used as a last resort as it can sometimes worsen TBM) We strongly recommend that you discuss your treatment options with a healthcare provider. | |
What is (are) Oral lichen planus ? | Oral lichen planus is a inflammatory condition that affects the inside of the mouth. Signs and symptoms include patches of fine white lines and dots most commonly in the inside of the cheeks, gums, and/or tongue. Most people with lichen planus experience no to few symptoms, others may have painful sores or ulcers in the mouth. Severe lichen planus slightly increases the risk for oral cancer. Oral lichen planus may occur alone or in combination with other skin forms of lichen planus. | |
What are the treatments for Oral lichen planus ? | How might oral lichen planus be treated? It is important to identify and remove any potential agent that might have caused a lichenoid reaction. Chemicals or medications associated with development of lichen planus include gold, antibiotics, arsenic, iodides, chloroquine, quinacrine, quinidine, antimony, phenothiazines, diuretics such as chlorothiazide, and many others.[2483] Consideration regarding role of drugs that were started in recent months prior to the on set of oral lichen planus, as well as any contact allergens identified by patch testing is recommended. Symptoms may improve with the following measures: Meticulous oral hygiene Stopping smoking Topical steroids as drops, pastes, gels or sprays (e.g., triamcinolone paste) Steroid injections (intralesional triamcinolone) Mouth rinse containing the calcineurin inhibitors: cyclosporin or tacrolimus In severe cases systemic corticosteroids may be used. Other possible therapeutic agents may include: Thalidomide Systemic retinoids (acitretin or isotretinoin) Griseofulvin Azathioprine Cyclophosphamide Dapsone Metronidazole Low molecular weight heparin | |

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) Atypical hemolytic uremic syndrome ? | Atypical hemolytic-uremic syndrome (aHUS) is a disease that causes abnormal blood clots to form in small blood vessels in the kidneys. These clots can cause serious medical problems if they restrict or block blood flow, including hemolytic anemia, thrombocytopenia, and kidney failure. It can occur at any age and is often caused by a combination of environmental and genetic factors. Genetic factors involve genes that code for proteins that help control the complement system (part of your bodys immune system). Environmental factors include certain medications (such as anticancer drugs), chronic diseases (e.g., systemic sclerosis and malignant hypertension), viral or bacterial infections, cancers, organ transplantation, and pregnancy. Most cases are sporadic. Less than 20 percent of all cases have been reported to run in families. When the disorder is familial, it can have an autosomal dominant or an autosomal recessive pattern of inheritance. Atypical hemolytic-uremic syndrome differs from a more common condition called typical hemolytic-uremic syndrome. The two disorders have different causes and different signs and symptoms. | |

What is (are) Duane syndrome type 1 ? | Duane syndrome type 1 is the most common type of Duane syndrome, an eye movement disorder that is present at birth. People with Duane syndrome have restricted ability to move the affected eye(s) outward toward the ear (abduction) and/or inward toward the nose (adduction). The different types are distinguished by the eye movements that are most restricted. Duane syndrome type 1 is characterized by absent to very restricted abduction and normal to mildly restricted adduction. The eye opening (palpebral fissure) narrows and the eyeball retracts into the orbit with adduction. With abduction, the reverse occurs. One or both eyes may be affected. The majority of cases are sporadic (not inherited), while about 10% are familial. 70% of affected people do not have any other abnormalities at birth (isolated Duane syndrome). | |

What are the treatments for Duane syndrome type 1 ? | How might Duane syndrome type 1 be treated? Management of Duane syndrome is mainly supportive. It may involve treatment of amblyopia ("lazy eye"); wearing glasses or contact lenses; the use of prisms to correct for abnormal head posture; or possible eye muscle surgery. The majority of people with Duane syndrome do not need surgery. However, surgery may be indicated if necessary to reduce severe misalignment of the eyes (strabismus); improve an unacceptable head position; treat a significant upshoot or downshoot; or fix displacement of the eyeball within the orbit (enophthalmos). Unfortunately, surgery does not restore function to the affected nerve and muscle, and no surgical technique has been completely successful in eliminating the abnormal eye movements. Surgery for Duane syndrome usually involves adjusting the other eye muscles to compensate and allow for better eye alignment. While it cannot fix the underlying problem, it can substantially improve signs or symptoms. Some surgical procedures or combinations of procedures may be successful in improving or eliminating head turns and strabismus. | |
What is (are) Scurvy ? | Scurvy is a condition that develops in people who do not consume an adequate amount of vitamin C in their diet. Although scurvy is relatively rare in the United States, it continues to be a problem in malnourished populations around the world (such as impoverished, underdeveloped third world countries). Early features of the condition include general weakness, fatigue and aching limbs. If left untreated, more serious problems can develop such as anemia, gum disease, and skin hemorrhages. Symptoms generally develop after at least 3 months of severe or total vitamin C deficiency. Treatment consists of vitamin C supplements taken by mouth. | |

What is (are) Baylisascaris infection ? | Baylisascaris roundworms are intestinal parasites found in many different animals. Baylisascaris infection in humans is uncommon but can be severe. While Baylisascaris can infect different types of animals, Baylisascaris procyonis, carried by raccoons, is thought to pose the greatest risk to humans because raccoons often live in close proximity to humans. Humans can acquire the parasite by ingesting the eggs of infected raccoons. Young children are at greatest risk for Baylisascaris infection because they are more likely to put contaminated soil in their mouths. Though rare, human infections can be severe if the parasite invades the eye (ocular larva migrans), organs (visceral larva migrans), or the brain (neural larva migrans). Symptoms of a Baylisascaris infection may include nausea, fatigue, an enlarged liver, loss of coordination, lack of muscle control, blindness, and coma. Baylisascaris infections cannot be spread from one person to another. No drug has been found to be completely effective against Baylisascaris infections in humans though albendazole has been used in some cases. | |
What are the treatments for Baylisascaris infection ? | How might Baylisascaris infection be treated? No drug has been found to be completely effective in treating Baylisascaris infections in humans. Albendazole is currently considered to be the drug of choice. Corticosteroids may also be given to reduce inflammation. In many cases, significant damage has already occurred by the time treatment has started. Early diagnosis and treatment provide the best chance of recovery. | |

What is (are) Mondor disease ? | Mondor disease is a rare condition that is characterized by scarring and inflammation of the veins located just beneath the skin of the chest. The affected veins are initially red and tender and subsequently become a painless, tough, fibrous band that is accompanied by tension and retraction of the nearby skin. In most cases, the condition is benign and resolves on its own; however, Mondor disease can rarely be associated with breast cancer. Although the condition most commonly affects the chest, Mondor disease of other body parts (including the penis, groin, and abdomen) has been described, as well. Mondor disease is thought to occur when pressure or trauma on the veins causes blood to stagnate. In most cases, the condition arises after recent breast surgery, but it can also be associated with physical strain and/or tight-fitting clothing (i.e. bras). Treatments are available to help relieve symptoms until the condition resolves. | |
What is (are) Protein C deficiency ? | Protein C deficiency is a disorder that increases a person's risk to develop abnormal blood clots. The condition can be mild or severe. People with mild protein C deficiency are at risk for a type of clot called deep vein thrombosis (DVT). A DVT can travel through the bloodstream and become stuck in the lung, which can cause a life-threatening pulmonary embolism. Most people with mild protein C deficiency never develop abnormal blood clots, but certain factors can increase the risk to develop a blood clot. In severe protein C deficiency, affected infants develop a life-threatening blood clotting disorder called purpura fulminans soon after birth. This is characterized by blood clots that block normal blood flow and can lead to death of body tissues (necrosis). Abnormal bleeding can occur in various parts of the body causing purple patches on the skin. Protein C deficiency may be inherited or acquired. The inherited form is caused by mutations in the PROC gene and is inherited in an autosomal dominant manner. Most people with protein C deficiency do not have any symptoms and require no specific treatment. However, in situations of clot risk such as pregnancy, surgery or trauma, prevention treatment may be indicated. Patients with the severe form of the disease are treated depending on the symptoms. A protein C concentrate is effective in many cases. Liver transplant may cure the babies with this disease. | |

In these cases, the sign or symptom may be rare or common. | |
What causes Protein C deficiency ? | What causes protein C deficiency? Protein C deficiency can be inherited or acquired later in life. Inherited protein C deficiency is caused by mutations in the gene that provides instructions for making protein C, called the PROC gene. These mutations disrupt the protein's ability to control blood clotting. If protein C cannot control blood clotting, abnormal blood clots may form. Acquired protein C deficiency may be caused by large blood clots, liver disease, disseminated intravascular coagulation (DIC), infection (sepsis), and vitamin K deficiency. Treatment with warfarin or certain types of chemotherapy can also cause acquired protein C deficiency. | |
Is Protein C deficiency inherited ? | How is protein C deficiency inherited? Hereditary protein C deficiency is inherited in an autosomal dominant manner. This means that having only one mutated copy of the responsible gene in each cell is enough to cause mild protein C deficiency. A mutated copy of the gene can be inherited from a person's mother or father. People who inherit two mutated copies of the gene have severe protein C deficiency. | |
How to diagnose Protein C deficiency ? | How is protein C deficiency diagnosed? A diagnosis of protein C deficiency might be suspected in someone with a deep venous thrombosis (DVT) or a pulmonary embolism, especially if it occurs in a relatively young person (less than 50 years old) or has formed in an unusual location, such as the veins leading to the liver or kidney or the blood vessels of the brain. Laboratory tests are usually be done to look at the function or quantity of protein C in the blood. Functional tests are usually ordered, along with other tests for abnormal blood clotting, to screen for normal activity of protein C. Based on those results, concentrations of protein C may be measured to look for decreased production due to an acquired or inherited condition and to classify the type of deficiency. If the shortage of protein C is due to an inherited genetic change, the quantity of protein C available and the degree of activity can be used to help determine whether a person is heterozygous or homozygous for the mutation. Genetic testing is not necessary to make a diagnosis. | |
What are the treatments for Protein C deficiency ? | How might protein C deficiency be treated? Most people with mild protein C deficiency never develop abnormal blood clots and thus do not require treatment. However, people who have experienced a deep venous thrombosis (DVT) or a pulmonary embolism are usually treated with blood-thinning drugs such as heparin or warfarin, which help to prevent another blood clot from developing in the future. Preventative treatment with these blood-thinning drugs may also be considered in those with a family history of blood clotting, as well as in higher risk situations such as pregnancy. A protein C concentrate (Ceprotin) was approved by the Food and Drug Administration in 2007 for the treatment of protein C deficiency. High doses of intravenous protein C concentrates can help thin the blood and protect from blood clots. It can also be used a preventative treatment against blood clots during surgery, pregnancy delivery, prolonged immobility, or overwhelming infection in the blood stream (sepsis). Currently, no guidelines exist as to which patients should receive protein C concentrate. It is typically given only at times of increased risk for clotting, or when the blood thinner heparin by itself cannot be safely given because it would lead to an increased risk for bleeding. However, in those with severe protein C who have had severe bleeding complications on long-term blood thinning therapy, protein C concentrate has been used on a regular basis. | |
What is (are) 15q11.2 microdeletion ? | 15q11.2 microdeletion refers to a chromosome abnormality in which a tiny piece of genetic material on the long arm of chromosome 15 (at a location designated q11.2) is missing (deleted). The features of people with a 15q11.2 microdeletion vary widely. The most common features include developmental, motor, and language delays; behavior and emotional problems; attention deficit disorders; and autism spectrum disorder. Other features may include birth defects and seizures. However, some people have no apparent physical, learning, or behavior problems. A 15q11.2 microdeletion may occur randomly for the first time in an affected person, or it may be inherited from a parent. Treatment depends on the signs and symptoms in each person. | |
What are the symptoms of 15q11.2 microdeletion ? | What are the signs and symptoms of 15q11.2 microdeletion? The signs and symptoms in people with a 15q11.2 microdeletion can vary widely. Some people with the microdeletion don't have any apparent features, while others are more severely affected. When not all people with a genetic abnormality are affected, the condition is said to have reduced penetrance. When signs and symptoms vary among affected people, the condition is said to have variable expressivity. The most commonly reported features in people with a 15q11.2 microdeletion include neurological dysfunction, developmental delay, language delay, motor delay, ADD/ADHD, and autism spectrum disorder. Other signs and symptoms that have been reported include seizures; abnormally shaped ears; abnormalities of the palate (roof of the mouth); memory problems; behavioral problems; and mental illness. While some babies with a 15q11.2 microdeletion are born with a minor or serious birth defect, many babies are born completely healthy. You may read additional information about this microdeletion in Unique's guide entitled '15q11.2 microdeletions.' This guide contains information from both the published medical literature and from a survey of members with a 15q11.2 microdeletion. The Human Phenotype Ontology provides the following list of signs and symptoms for 15q11.2 microdeletion. 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 cardiovascular system morphology - Ataxia - Autistic behavior - Autosomal dominant inheritance - Broad forehead - Cleft palate - Clumsiness - Delayed speech and language development - Feeding difficulties - Happy demeanor - Hypertelorism - Incomplete penetrance - Intellectual disability - Muscular hypotonia - Obsessive-compulsive behavior - Plagiocephaly - Seizures - Slender finger - 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 causes 15q11.2 microdeletion ? | What causes a 15q11.2 microdeletion? A 15q11.2 microdeletion may occur randomly for the first time in an affected person (a de novo mutation), or it may be inherited from a parent with the microdeletion. A blood test to look at the parents' chromosomes is needed to find out how the microdeletion occurred. When a 15q11.2 microdeletion occurs as a de novo mutation, it is due to a random error - either during the formation of a parent's egg or sperm cell, or very soon after conception (fertilization of the egg). A parent with the microdeletion has a 50% chance with each pregnancy to pass on the microdeletion. The features of 15q11.2 microdeletion occur because the deleted region of the chromosome contains several genes that are important for normal growth and development. It is not yet clear why there is a large range of features and severity among people with a 15q11.2 microdeletion, or why some people are unaffected. | |
What is (are) Oculocutaneous albinism type 2 ? | Oculocutaneous albinism type 2 is a genetic condition that affects the coloring (pigmentation) of the skin, hair, and eyes. Affected individuals typically have very fair skin and white or light-colored hair. Long-term sun exposure greatly increases the risk of skin damage and skin cancers, including an aggressive form of skin cancer called melanoma, in people with this condition. This condition also reduces pigmentation of the colored part of the eye (the iris) and the light-sensitive tissue at the back of the eye (the retina). People with this condition usually have vision problems such as reduced sharpness; nystagmus and strabismus; and increased sensitivity to light (photophobia). This condition is caused by mutations in the OCA2 gene and is inherited in an autosomal recessive fashion. | |

What is (are) 11-beta-hydroxylase deficiency ? | Congenital adrenal hyperplasia (CAH) due to 11-beta-hydroxylase deficiency is one of a group of disorders (collectively called congenital adrenal hyperplasia) that affect the adrenal glands. In this condition, the adrenal glands produce excess androgens (male sex hormones). This condition is caused by mutations in the CYP11B1 gene and is inherited in an autosomal recessive pattern. There are two types, the classic form and the non-classic form. Females with the classic form have ambiguous external genitalia with normal internal reproductive organs. Males and females with the classic form have early development of their secondary sexual characteristics (precocious puberty). The early growth spurt can prevent growth later in adolescence and lead to short stature in adulthood. About two-thirds of individuals with the classic form have high blood pressure which develops in the first year of life. | |

Is 11-beta-hydroxylase deficiency inherited ? | How is 11-beta-hydroxylase deficiency inherited? This condition 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 11-beta-hydroxylase deficiency ? | Is genetic testing available for 11-beta-hydroxylase deficiency? Yes. GeneTests lists laboratories offering clinical genetic testing for this condition. Clinical genetic tests are ordered to help diagnose a person or family and to aid in decisions regarding medical care or reproductive issues. Talk to your health care provider or a genetic professional to learn more about your testing options. | |
What is (are) Serpiginous choroiditis ? | Serpiginous choroiditis is a rare inflammatory eye condition that typically develops between age 30 and 70 years. Affected individuals have lesions in the eye that last from weeks to months and involve scarring of the eye tissue. Recurrence of these lesions is common in serpiginous choroiditis. Vision loss may occur in one or both eyes when the macula is involved. Treatment options involve anti-inflammatory and immune-suppressing medications. | |
What causes Serpiginous choroiditis ? | What causes serpiginous choroiditis? The cause of serpiginous choroiditis is unknown. Speculation exists regarding an association with exposure to various toxic compounds and/or infectious agents. Some researchers believe the condition is related to an organ-specific autoimmune inflammatory process. | |
Is Serpiginous choroiditis inherited ? | Can I inherit serpiginous choroiditis if my mother has the condition? No familial predillection or propensity has been described. | |
What are the treatments for Serpiginous choroiditis ? | Is there any treatment for serpiginous choroiditis? There are a few treatment options for individuals with serpiginous choroiditis. Treatment may involve an anti-inflammatory medication, such as prednisone, or an immune system suppressing combination of prednisone, cyclosporine, and azathioprine. Additionally, the role of cyclosporine alone has been investigated. These treatments may be administered for a long period of time to prevent recurrences. A serious complication of serpiginous choroiditis is choroidal neovascularization. Laser photocoagulation or surgery may be helpful in some of these cases. | |

What is (are) Schizencephaly ? | Schizencephaly is a rare congenital (present from birth) brain malformation in which abnormal slits or clefts form in the cerebral hemispheres of the brain. The signs and symptoms of this condition may include developmental delay, seizures, and problems with brain-spinal cord communication. Affected people may also have an abnormally small head (microcephaly); hydrocephalus; intellectual disability; partial or complete paralysis; and/or poor muscle tone (hypotonia). Severity of symptoms depends on many factors including the extent of the clefting and whether or not other brain abnormalities are present. Although the exact cause of schizencephaly is unknown, it has been linked to a variety of genetic and non-genetic factors. Treatment generally consists of physical therapy and drugs to prevent seizures. In cases that are complicated by hydrocephalus, a surgically implanted tube, called a shunt, is often used to divert fluid to another area of the body where it can be absorbed. | |

What causes Schizencephaly ? | What causes schizencephaly? The exact cause of schizencephaly is unknown. A small number of people with schizencephaly are found to have changes (mutations) in one of four genes: EMX2, SIX3, SHH, and COL4A1. Rarely, schizencephaly can affect more than one family member. This supports a genetic cause in some cases. Schizencephaly has also been linked to a variety of non-genetic factors, including young maternal age and certain medications and infections that can cause vascular disruptions (disruption of blood flow or blood supply) in a developing baby. | |
Is Schizencephaly inherited ? | Is schizencephaly inherited? Schizencephaly is not thought to be inherited in most cases and it rarely affects more than one person in a family. A few cases of familial schizencephaly have been linked to changes (mutations) in the EMX2 gene. | |
How to diagnose Schizencephaly ? | Is genetic testing available for schizencephaly? In rare cases, people affected by schizencephaly are found to have changes (mutations) in one of four genes: EMX2, SIX3, SHH, and COL4A1. Genetic testing is available for these families. How is schizencephaly diagnosed? Schizencephaly is typically diagnosed by computed tomography (CT) and/or magnetic resonance imaging (MRI). A CT scan is an imaging method that uses x-rays to create pictures of cross-sections of the body, while an MRI scan uses powerful magnets and radio waves to create pictures of the brain and surrounding nerve tissues. Both of these imaging methods can be used to identify brain abnormalities such as the slits or clefts found in people with schizencephaly. In some cases, schizencephaly can also be diagnosed prenatally (before birth) on ultrasound after 20 weeks gestation. If clefting is seen on ultrasound, an MRI scan of the developing baby may be recommended to confirm the diagnosis. | |
What are the treatments for Schizencephaly ? | How might schizencephaly be treated? The best treatment options for people with schizencephaly depend on many factors, including the severity of the condition and the signs and symptoms present. For example, people with developmental delay (i.e. delayed motor milestones) or partial paralysis may be referred for physical therapy and/or occupational therapy. Medications are often prescribed to prevent seizures. In cases that are complicated by hydrocephalus, a surgically implanted tube, called a shunt, is often used to divert fluid to another area of the body where it can be absorbed. | |

What is (are) Familial stomach cancer ? | Familial stomach cancer is a cluster of stomach cancer within a family. Most cases of stomach cancer occur sporadically in people with little to no family history of the condition; however, approximately 10% of stomach cancer is considered "familial." Although the underlying cause of some familial cases is unknown, genetic changes (mutations) are identified in a subset of people affected by gastric cancer. Hereditary cancer syndromes associated with a predisposition to gastric cancer include hereditary diffuse gastric cancer, Lynch syndrome, Li-Fraumeni syndrome, familial adenomatous polyposis, and Peutz-Jeghers syndrome. In other families, the cluster of stomach cancers may be due to a combination of gene(s) and/or other shared factors such as environment and lifestyle. Depending on the estimated risk, high-risk cancer screening and/or prophylactic surgeries are typically recommended in people who have an increased risk for stomach cancer based on their personal and/or family histories. | |
What is (are) Oculopharyngeal muscular dystrophy ? | Oculopharyngeal muscular dystrophy (OPMD) is a genetic muscle disorder with onset during adulthood, most often between 40 and 60 years of age. This condition is characterized by slowly progressive muscle disease (myopathy) affecting the muscles of the upper eyelids and the throat. There are two types of OPMD, which are distinguished by their patterns of inheritance. They are known as the autosomal dominant and autosomal recessive types. Both types are caused by mutations in the PABPN1 gene. | |
What are the symptoms of Oculopharyngeal muscular dystrophy ? | What are the signs and symptoms of Oculopharyngeal muscular dystrophy? There are many signs and symptoms of oculopharyngeal muscular dystrophy (OPMD), although the specific symptoms and age of onset varies among affected individuals. Most people show one or more symptoms by the age of 70. The most common symptoms of OPMD include: Muscle weakness (also known as myopathy) Droopy eyelids (also known as ptosis) Difficulty swallowing (also known as dysphagia) Double vision Tongue weakness Upper and/or lower body weakness Weakness of the muscles in the face Voice disorders (in about half of people with this condition) The Human Phenotype Ontology provides the following list of signs and symptoms for Oculopharyngeal muscular dystrophy.

What causes Oculopharyngeal muscular dystrophy ? | What causes oculopharyngeal muscular dystrophy? Oculopharyngeal muscular dystrophy (OPMD) is caused by mutations in the PABPN1 gene. The PABPN1 gene provides instructions for making a protein that is active (expressed) throughout the body. In cells, the PABPN1 protein plays an important role in processing molecules called messenger RNAs (mRNAs), which serve as genetic blueprints for making proteins. The protein acts to protect the mRNA from being broken down and allows it to move within the cell. Mutations in the PABPN1 gene that cause OPMD result in a PABPN1 protein that forms clumps within muscle cells, and hence they cannot be broken down. These clumps are thought to impair the normal function of muscle cells and eventually cause cells to die. The progressive loss of muscle cells most likely causes the muscle weakness seen in people with OPMD. It is not known why abnormal PABPN1 proteins seem to affect muscle cells in only certain parts of the body. | |

How to diagnose Oculopharyngeal muscular dystrophy ? | Is genetic testing available for oculopharyngeal muscular dystrophy? Genetic testing is available for oculopharyngeal muscular dystrophy (OPMD). GeneTests lists the names of laboratories that are performing genetic testing for this condition. To view the contact information for the clinical laboratories conducting testing click here. Please note that most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, individuals that are interested in learning more will need to work with a health care provider or a genetics professional. | |
What are the treatments for Oculopharyngeal muscular dystrophy ? | How might oculopharyngeal muscular dystrophy be treated? Treatment of oculopharyngeal muscular dystrophy (OPMD) mainly focuses on the specific signs and symptoms present in each individual. Severe drooping of the eyelid (ptosis) may be treated with plastic surgery on the eyelid (blepharoplasty). The goal of this surgery is to raise the eyelid so that the affected individual can see. Individuals with severe difficulty swallowing (dysphagia) may have a surgical procedure known as cricopharyngeal myotomy. In this procedure, the cricopharyngeal muscle of the throat is cut so that when swallowing occurs, the muscle remains relaxed allowing the passage of food or liquid. Orthopedic devices such as canes, leg braces, or walkers can assist individuals who have difficulty walking. Other treatment is symptomatic and supportive. | |
What is (are) Hypersensitivity vasculitis ? | Hypersensitivity vasculitis is an extreme reaction to a drug, infection, or foreign substance that leads to inflammation and damage to blood vessels of the skin. Signs and symptoms may include purple-colored spots and patches on the skin; skin lesions on the legs, buttocks, or trunk; blisters on the skin; hives (urticaria); and/or open sores with dead tissue (necrotic ulcers). This condition is caused by an allergic reaction to a drug or other foreign substance. This condition usually goes away over time; but on occasion, people can have repeated episodes. |
