What causes Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency ? 

What causes non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency? Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NCAH) is caused by changes (mutations) in the CYP21A2 gene. This gene provides instructions for making an enzyme called 21-hydroxylase, which is found in the adrenal glands. The adrenal glands are cone-shaped organs that sit on top of the kidneys and are responsible for releasing various types of hormones that the body needs to function. Mutations in CYP21A2 lead to deficient levels of 21-hydroxylase which cause low levels of hormones such as cortisol and/or aldosterone and an overproduction of androgens (male hormones such as testosterone). Cortisol is a hormone that affects energy levels, blood sugar levels, blood pressure, and the body's response to stress, illness, and injury. Aldosterone helps the body maintain the proper level of sodium (salt) and water and helps maintain blood pressure. Irregular levels of these hormones lead to the signs and symptoms of NCAH. The amount of functional 21-hydroxylase enzyme determines the severity of the disorder. People with NCAH have CYP21A2 mutations that result in the production of reduced amounts of the enzyme, but more enzyme than the classic form of congenital adrenal hyperplasia.
Is Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency inherited ? 

Is non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency inherited? Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NCAH) is inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.
How to diagnose Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency ? 

How is non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency diagnosed? A diagnosis of non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NCAH) is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. This may include a blood test to measure the concentration of 17-hydroxyprogesterone (17-OHP) and/or an adrenocorticotropic hormone (ACTH) stimulation test. An ACTH stimulation test involves measuring the concentration of 17-OHP in the blood before ACTH is administered and 60 min after ACTH is given.
What are the treatments for Non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency ? 

How might non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency be treated? In some cases, people affected by non-classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (NCAH) may not require any treatment. Many are asymptomatic throughout their lives, although symptoms may develop during puberty, after puberty, or post partum. If symptoms are present, a glucocorticoid called dexamethasone is often recommended. Dexamethasone can treat irregular menstruation, acne, and excess body hair (hirsutism).
What is (are) Central serous chorioretinopathy ? 

Central serous chorioretinopathy is a disease that causes fluid to build up under the retina, the back part of the inner eye that sends sight information to the brain. The fluid leaks from the choroid (the blood vessel layer under the retina). The cause of this condition is unknown but stress can be a risk factor. Signs and symptoms include dim and blurred blind spot in the center of vision, distortion of straight lines and seeing objects as smaller or farther away. Many cases of central serous chorioretinopathy improve without treatment after 1-2 months. Laser treatment may be an option for other individuals.

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) Budd-Chiari syndrome ? 

Budd-Chiari syndrome is a rare disorder characterized by narrowing and obstruction of the veins of the liver. This narrowing or obstruction slows or prevents blood from flowing out of the liver and back to the heart which can lead to liver damage. While some people experience no symptoms, many experience fatigue, abdominal pain, nausea, and jaundice. Other associated findings include an accumulation of fluid in the abdomen (ascites), an enlarged spleen and/or liver, and severe bleeding in the esophagus. The severity of the disorder varies from case to case, depending on the site and number of affected veins. Drugs may be used to dissolve or decrease the size of the obstruction (if it is a clot). In some cases surgery is performed. In most cases, the cause of Budd-Chiari syndrome is unknown.

What is (are) Hanhart syndrome ? 

Hanhart syndrome is a rare condition that primarily affects the craniofacial region and the limbs (arms and legs). People affected by this condition are often born with a short, incompletely developed tongue; absent or partially missing fingers and/or toes; abnormalities of the arms and/or legs; and an extremely small jaw. The severity of these physical abnormalities varies greatly among affected people, and children with this condition often have some, but not all, of the symptoms. The cause of Hanhart syndrome is not fully understood. Treatment depends on the signs and symptoms present in each person.
What are the symptoms of Hanhart syndrome ? 

What are the signs and symptoms of Hanhart syndrome? The signs and symptoms of Hanhart syndrome vary, but may include: Small mouth Short, incompletely developed tongue (hypoglossia) Absent, partially missing, or shortened fingers and/or toes Jaw abnormalities such as micrognathia, retrognathia (receding jaw), or partially missing mandible (lower jaw) High-arched, narrow, or cleft palate Absent or unusually formed arms and/or legs Missing teeth Absence of major salivary glands Some infants with Hanhart syndrome may be born with paralysis of certain areas of the face. If the tongue and/or mouth are affected, this can worsen feeding difficulties that are already present due to the craniofacial abnormalities listed above.

What is (are) Nonbullous congenital ichthyosiform erythroderma ? 

Nonbullous congenital ichthyosiform erythroderma (NBCIE) is a specific type of ichthyosis mainly affecting the skin. Most infants with NBCIE are born with a tight, shiny covering on their skin, called a collodion membrane, which is typically shed within a few weeks. Other signs and symptoms include redness of the skin (erythroderma); fine, white scales on the skin; and thickening of the skin on the palms and soles of feet (palmoplantar keratoderma). Some people with NBCIE also have outward turning eyelids (ectropion); outward turning lips (eclabium); and nails that do not grow normally (nail dystrophy). NBCIE may be caused by mutations in any one of at least three genes: ALOX12B, ALOXE3 or NIPAL4. In some people with NBCIE, the cause of the disorder is unknown.
