Is Best vitelliform macular dystrophy inherited ? 

How is Best vitelliform macular dystrophy inherited? Best vitelliform macular dystrophy (BVMD) is most commonly inherited in an autosomal dominant manner, although a few cases with autosomal recessive inheritance have been reported. In autosomal dominant inheritance, having one changed (mutated) copy of the responsible gene in each cell is enough to cause symptoms of the condition. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated gene. Most people with BVMD have an affected parent, but some people have the condition as the result of a new mutation that occurred for the first time. Autosomal recessive inheritance means that a person must have a mutation in both copies of the responsible gene in each cell to be affected. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.
How to diagnose Best vitelliform macular dystrophy ? 

How is Best vitelliform macular dystrophy diagnosed? Best vitelliform macular dystrophy (BVMD) may be diagnosed based on the findings on an exam of the fundus (the interior surface of the eye opposite the lens); an electrooculogram (EOG); and the family history. An eye exam may include other tests as well. A fundus exam may show a typical yellow yolk-like macular lesion. An EOG is usually abnormal in affected people, but occasionally, people with signs of BVMD and a mutation in the BEST1 gene have a normal EOG. The family history in affected people is often consistent with either autosomal dominant or autosomal recessive inheritance. Genetic testing may also be used to make a diagnosis of BVMD. A BEST1 mutation is detected in about 96% of affected people who have an affected family member. In people with no family history of BVMD, the mutation detection rate ranges between 50-70%. The exact type of genetic test ordered to confirm a diagnosis may depend on a person's ancestry, family history, and/or whether other eye disorders are also being considered.
What are the treatments for Best vitelliform macular dystrophy ? 

How might Best vitelliform macular dystrophy be treated? There is no specific treatment for Best vitelliform macular dystrophy (BVMD) at this time. Low vision aids help affected people with significant loss of visual acuity. Laser photocoagulation, photodynamic therapy, and anti-VEGF (vascular endothelial growth factor) agents such as bevacizumab have shown limited success in treating some of the secondary features of BVMD such as choroidal neovascularization (when abnormal blood vessels grow under the macula and retina).
What are the symptoms of Onychotrichodysplasia and neutropenia ?

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) Autosomal recessive inheritance - Chronic irritative conjunctivitis - Concave nail - Curly eyelashes - Curly hair - Hypoplastic fingernail - Intellectual disability, mild - Lymphocytosis - Neutropenia - Recurrent infections - Short eyelashes - Sparse pubic hair - Trichorrhexis nodosa - 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) Hirschsprung's disease ?

What causes Hirschsprung's disease ? 

What causes Hirschsprung disease? There are a number of different causes of Hirschsprung disease (HSCR). For example, HSCR may occur as: A part of a syndrome In association with a chromosome anomaly (such as trisomy 21 or Down syndrome)  Along with other birth defects but not as a part of a known syndrome As an isolated condition
Is Hirschsprung's disease inherited ? 

Is Hirschsprung's disease inherited? Hirschsprung's disease (HSCR) usually occurs occurs by itself without other symptoms and is called isolated HSCR. Isolated HSCR has multifactorial inheritance, which means that multiple genes interact with environmental factors to cause the condition. When someone has a child with isolated HSCR, the overall risk to have another child with the condition is 4%. There are some factors that can change the risk. For example, the risk is higher if the sibling has long-segment disease rather than short-segment disease. Also males are more likely than females to develop HSCR. Another factor is if the siblings have the same or different parents.  If HSCR occurs as part of a genetic syndrome, then it is inherited in a specific pattern. For example, the inheritance may be autosomal recessive, autosomal dominant, or X-linked recessive, depending on the exact cause of the syndrome.  Individuals who are interested in learning about their personal risks or risks to family members should speak with their health care provider or a genetics professional.

What is (are) Graves' disease ? 

Graves' disease is an autoimmune disorder that leads to overactivity of the thyroid gland (hyperthyroidism). It is caused by an abnormal immune system response that causes the thyroid gland to produce too much thyroid hormones. Graves disease is the most common cause of hyperthyroidism and occurs most often in women over age 20. However, the disorder may occur at any age and may affect males as well. Treatment may include radioiodine therapy, antithyroid drugs, and/or thyroid surgery.

What is (are) COACH syndrome ? 

COACH syndrome is a condition that mainly affects the brain and liver.  Most individuals with COACH syndrome have mental retardation, liver problems (fibrosis), and difficulty with movement (ataxia).  Some may also have an abnormality of the eye (called a coloboma) or abnormal eye movements (such as nystagmus).  This condition is inherited in an autosomal recessive manner; 70% of cases are thought to be caused by mutations in the TMEM67 gene.  COACH syndrome is considered a rare form of another condition, Joubert syndrome.

How to diagnose COACH syndrome ? 

How is COACH syndrome diagnosed? While there are no official guidelines, a diagnosis of COACH syndrome can be made when an individual is found to have both a particular malformation of the brain called cerebellar vermis hypoplasia (also referred to as the "molar tooth sign" due to the characteristic look of this malformation on brain imaging) and liver disease (specifically fibrosis).
What is (are) Primary central nervous system lymphoma ? 

Primary central nervous system lymphoma (primary CNS lymphoma) is a rare form of non-Hodgkin lymphoma in which cancerous cells develop in the lymph tissue of the brain and/or spinal cord. Because the eye is so close to the brain, primary CNS lymphoma can also start in the eye (called ocular lymphoma). The signs and symptoms vary based on which parts of the central nervous system are affected, but may include nausea and vomiting; seizures; headaches; arm or leg weakness; confusion; double vision and/or hearing loss. The exact underlying cause of primary CNS lymphoma is poorly understood; however, people with a weakened immune system (such as those with acquired immunodeficiency syndrome) or who have had an organ transplant appear to have an increased risk of developing the condition. Treatment varies based on the severity of the condition and location of the cancerous cells.

What is (are) Imerslund-Grasbeck syndrome ? 

Imerslund-Grasbeck syndrome (IGS) is a rare condition characterized by vitamin B12 deficiency, often causing megaloblastic anemia. IGS usually appears in childhood. Other features may include failure to thrive, infections, and neurological damage. Mild proteinuria (with no signs of kidney disease) is present in about half of affected individuals. IGS is caused by mutations in either the CUBN or AMN gene and is inherited in an autosomal recessive manner. Treatment includes life-long vitamin B12 injections, with which affected individuals can stay healthy for decades.
