Question: What is (are) familial isolated pituitary adenoma ?
Answer: Familial isolated pituitary adenoma (FIPA) is an inherited condition characterized by development of a noncancerous tumor in the pituitary gland (called a pituitary adenoma). The pituitary gland, which is found at the base of the brain, produces hormones that control many important body functions.  Tumors that form in the pituitary gland can release excess levels of one or more hormones, although some tumors do not produce hormones (nonfunctioning pituitary adenomas). Those that do are typically distinguished by the particular hormones they produce. Prolactinomas are the most common tumors in FIPA. These tumors release prolactin, a hormone that stimulates breast milk production in females. Both women and men can develop prolactinomas, although they are more common in women. In women, these tumors may lead to changes in the menstrual cycle or difficulty becoming pregnant. Some affected women may produce breast milk, even though they are not pregnant or nursing. In men, prolactinomas may cause erectile dysfunction or decreased interest in sex. Rarely, affected men produce breast milk. Large prolactinomas can press on nearby tissues such as the nerves that carry information from the eyes to the brain (the optic nerves), causing problems with vision.  Another type of tumor called somatotropinoma is also common in FIPA. These tumors release growth hormone (also called somatotropin), which promotes growth of the body. Somatotropinomas in children or adolescents can lead to increased height (gigantism), because the long bones of their arms and legs are still growing. In adults, growth of the long bones has stopped, but the tumors can cause overgrowth of the hands, feet, and face (acromegaly) as well as other tissues.  Less common tumor types in FIPA include somatolactotropinomas, nonfunctioning pituitary adenomas, adrenocorticotropic hormone-secreting tumors (which cause a condition known as Cushing disease), thyrotropinomas, and gonadotropinomas. In a family with the condition, affected members can develop the same type of tumor (homogenous FIPA) or different types (heterogenous FIPA).  In FIPA, pituitary tumors usually occur at a younger age than sporadic pituitary adenomas, which are not inherited. In general, FIPA tumors are also larger than sporadic pituitary tumors. Often, people with FIPA have macroadenomas, which are tumors larger than 10 millimeters.  Familial pituitary adenomas can occur as one of many features in other inherited conditions such as multiple endocrine neoplasia type 1 and Carney complex; however, in FIPA, the pituitary adenomas are described as isolated because only the pituitary gland is affected.

Question: How many people are affected by familial isolated pituitary adenoma ?
Answer: Pituitary adenomas, including sporadic tumors, are relatively common; they are identified in an estimated 1 in 1,000 people. FIPA, though, is quite rare, accounting for approximately 2 percent of pituitary adenomas. More than 200 families with FIPA have been described in the medical literature.

Question: What are the genetic changes related to familial isolated pituitary adenoma ?
Answer: FIPA can be caused by mutations in the AIP gene. The function of the protein produced from this gene is not well understood, but it is thought to act as a tumor suppressor, which means it helps prevent cells from growing and dividing in an uncontrolled way. Mutations in the AIP gene alter the protein or reduce the production of functional protein. These changes likely impair the ability of the AIP protein to control the growth and division of cells, allowing pituitary cells to grow and divide unchecked and form a tumor. It is not known why the pituitary gland is specifically affected or why certain types of pituitary adenomas develop.  AIP gene mutations account for approximately 15 to 25 percent of cases of FIPA. Somatotropinomas are the most common type of tumor in these individuals. The tumors usually occur at a younger age, often in childhood, and are larger than FIPA tumors not caused by AIP gene mutations. The other genetic causes of FIPA are unknown.

Question: Is familial isolated pituitary adenoma inherited ?
Answer: FIPA is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. However, only 20 to 30 percent of individuals with an AIP gene mutation develop a pituitary adenoma. This phenomenon, in which some individuals with a mutation do not develop the features of a particular disorder, is called incomplete penetrance.

Topic: CAV3-related distal myopathy
Question: What is (are) CAV3-related distal myopathy ?
Answer: CAV3-related distal myopathy is one form of distal myopathy, a group of disorders characterized by weakness and loss of function affecting the muscles farthest from the center of the body (distal muscles), such as those of the hands and feet. People with CAV3-related distal myopathy experience wasting (atrophy) and weakness of the small muscles in the hands and feet that generally become noticeable in adulthood. A bump or other sudden impact on the muscles, especially those in the forearms, may cause them to exhibit repetitive tensing (percussion-induced rapid contraction). The rapid contractions can continue for up to 30 seconds and may be painful. Overgrowth (hypertrophy) of the calf muscles can also occur in CAV3-related distal myopathy. The muscles closer to the center of the body (proximal muscles) such as the thighs and upper arms are normal in this condition.

Topic: CAV3-related distal myopathy
Question: What are the genetic changes related to CAV3-related distal myopathy ?
Answer: CAV3-related distal myopathy is part of a group of conditions called caveolinopathies, which are muscle disorders caused by mutations in the CAV3 gene. The CAV3 gene provides instructions for making a protein called caveolin-3, which is found in the membrane surrounding muscle cells. This protein is the main component of caveolae, which are small pouches in the muscle cell membrane. Within the caveolae, the caveolin-3 protein acts as a scaffold to organize other molecules that are important for cell signaling and maintenance of the cell structure.  CAV3 gene mutations result in a shortage of caveolin-3 protein in the muscle cell membrane and a reduction in the number of caveolae. Researchers suggest that a shortage of caveolae impairs the structural integrity of muscle cells, interferes with cell signaling, and causes the self-destruction of cells (apoptosis). The resulting degeneration of muscle tissue leads to the signs and symptoms of CAV3-related distal myopathy.  In addition to CAV3-related distal myopathy, CAV3 gene mutations can cause other caveolinopathies including limb-girdle muscular dystrophy, rippling muscle disease, isolated hyperCKemia, and a heart disorder called hypertrophic cardiomyopathy. Several CAV3 gene mutations have been found to cause different caveolinopathies in different individuals. It is unclear why a single CAV3 gene mutation may cause different patterns of signs and symptoms, even within the same family.

Topic: CAV3-related distal myopathy
Question: Is CAV3-related distal myopathy inherited ?
Answer: This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one parent with CAV3-related distal myopathy or another caveolinopathy. Rare cases result from new mutations in the gene and occur in people with no history of caveolinopathies in their family.

Topic: Ohdo syndrome, Say-Barber-Biesecker-Young-Simpson variant
Question: What is (are) Ohdo syndrome, Say-Barber-Biesecker-Young-Simpson variant ?
Answer: The Say-Barber-Biesecker-Young-Simpson (SBBYS) variant of Ohdo syndrome is a rare condition characterized by genital abnormalities in males, missing or underdeveloped kneecaps (patellae), intellectual disability, distinctive facial features, and abnormalities affecting other parts of the body.  Males with the SBBYS variant of Ohdo syndrome typically have undescended testes (cryptorchidism). Females with this condition have normal genitalia.  Missing or underdeveloped patellae is the most common skeletal abnormality associated with the SBBYS variant of Ohdo syndrome. Affected individuals also have joint stiffness involving the hips, knees, and ankles that can impair movement. Although joints in the lower body are stiff, joints in the arms and upper body may be unusually loose (lax). Many people with this condition have long thumbs and first (big) toes.  The SBBYS variant of Ohdo syndrome is also associated with delayed development and intellectual disability, which are often severe. Many affected infants have weak muscle tone (hypotonia) that leads to breathing and feeding difficulties.  The SBBYS variant of Ohdo syndrome is characterized by a mask-like, non-expressive face. Additionally, affected individuals may have distinctive facial features such as prominent cheeks, a broad nasal bridge or a nose with a rounded tip, a narrowing of the eye opening (blepharophimosis), droopy eyelids (ptosis), and abnormalities of the tear (lacrimal) glands. About one-third of affected individuals are born with an opening in the roof of the mouth called a cleft palate. The SBBYS variant of Ohdo syndrome can also be associated with heart defects and dental problems.

Topic: Ohdo syndrome, Say-Barber-Biesecker-Young-Simpson variant
Question: What are the genetic changes related to Ohdo syndrome, Say-Barber-Biesecker-Young-Simpson variant ?
Answer: The SBBYS variant of Ohdo syndrome is caused by mutations in the KAT6B gene. This gene provides instructions for making a type of enzyme called a histone acetyltransferase. These enzymes modify histones, which are structural proteins that attach (bind) to DNA and give chromosomes their shape. By adding a small molecule called an acetyl group to histones, histone acetyltransferases control the activity of certain genes. Little is known about the function of the histone acetyltransferase produced from the KAT6B gene. It appears to regulate genes that are important for early development, including development of the skeleton and nervous system.  The mutations that cause the SBBYS variant of Ohdo syndrome likely prevent the production of functional histone acetyltransferase from one copy of the KAT6B gene in each cell. Studies suggest that the resulting shortage of this enzyme impairs the regulation of various genes during early development. However, it is unclear how these changes lead to the specific features of the condition.

Topic: systemic scleroderma
Question: What are the genetic changes related to systemic scleroderma ?
Answer: Researchers have identified variations in several genes that may influence the risk of developing systemic scleroderma. The most commonly associated genes belong to a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria). Each HLA gene has many different normal variations, allowing each person's immune system to react to a wide range of foreign proteins. Specific normal variations of several HLA genes seem to affect the risk of developing systemic scleroderma.  Normal variations in other genes related to the body's immune function, such as IRF5 and STAT4, are also associated with an increased risk of developing systemic scleroderma. Variations in the IRF5 gene are specifically associated with diffuse cutaneous systemic scleroderma, and a variation in the STAT4 gene is associated with limited cutaneous systemic scleroderma. The IRF5 and STAT4 genes both play a role in initiating an immune response when the body detects a foreign invader (pathogen) such as a virus.  It is not known how variations in the associated genes contribute to the increased risk of systemic scleroderma. Variations in multiple genes may work together to increase the risk of developing the condition, and researchers are working to identify and confirm other genes associated with increased risk. In addition, a combination of genetic and environmental factors seems to play a role in developing systemic scleroderma.

Topic: systemic scleroderma
Question: Is systemic scleroderma inherited ?
Answer: Most cases of systemic scleroderma are sporadic, which means they occur in people with no history of the condition in their family. However, some people with systemic scleroderma have close relatives with other autoimmune disorders.  A small percentage of all cases of systemic scleroderma have been reported to run in families; however, the condition does not have a clear pattern of inheritance. Multiple genetic and environmental factors likely play a part in determining the risk of developing this condition. As a result, inheriting a genetic variation linked with systemic scleroderma does not mean that a person will develop the condition.

Topic: Bowen-Conradi syndrome
Question: What is (are) Bowen-Conradi syndrome ?
Answer: Bowen-Conradi syndrome is a disorder that affects many parts of the body and is usually fatal in infancy. Affected individuals have a low birth weight, experience feeding problems, and grow very slowly. Their head is unusually small overall (microcephaly), but is longer than expected compared with its width (dolichocephaly). Characteristic facial features include a prominent, high-bridged nose and an unusually small jaw (micrognathia) and chin. Affected individuals typically have pinky fingers that are curved toward or away from the ring finger (fifth finger clinodactyly) or permanently flexed (camptodactyly), feet with soles that are rounded outward (rocker-bottom feet), and restricted joint movement.  Other features that occur in some affected individuals include seizures; structural abnormalities of the kidneys, heart, brain, or other organs; and an opening in the lip (cleft lip) with or without an opening in the roof of the mouth (cleft palate). Affected males may have the opening of the urethra on the underside of the penis (hypospadias) or undescended testes (cryptorchidism).  Babies with Bowen-Conradi syndrome do not achieve developmental milestones such as smiling or sitting, and they usually do not survive more than 6 months.

Question: How many people are affected by Bowen-Conradi syndrome ?
Answer: Bowen-Conradi syndrome is common in the Hutterite population in Canada and the United States; it occurs in approximately 1 per 355 newborns in all three Hutterite sects (leuts). A few individuals from outside the Hutterite community with signs and symptoms similar to Bowen-Conradi syndrome have been described in the medical literature. Researchers differ as to whether these individuals have Bowen-Conradi syndrome or a similar but distinct disorder.

Topic: Bowen-Conradi syndrome
Question: What are the genetic changes related to Bowen-Conradi syndrome ?
Answer: Bowen-Conradi syndrome is caused by a mutation in the EMG1 gene. This gene provides instructions for making a protein that is involved in the production of cellular structures called ribosomes, which process the cell's genetic instructions to create new proteins. Ribosomes are assembled in a cell compartment called the nucleolus.  The particular EMG1 gene mutation known to cause Bowen-Conradi syndrome is thought to make the protein unstable, resulting in a decrease in the amount of EMG1 protein that is available in the nucleolus. A shortage of this protein in the nucleolus would impair ribosome production, which may reduce cell growth and division (proliferation); however, it is unknown how EMG1 gene mutations lead to the particular signs and symptoms of Bowen-Conradi syndrome.

Topic: Bowen-Conradi syndrome
Question: Is Bowen-Conradi syndrome inherited ?
Answer: 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.

Topic: lactose intolerance
Question: What is (are) lactose intolerance ?
Answer: Lactose intolerance is an impaired ability to digest lactose, a sugar found in milk and other dairy products. Lactose is normally broken down by an enzyme called lactase, which is produced by cells in the lining of the small intestine.  Congenital lactase deficiency, also called congenital alactasia, is a disorder in which infants are unable to break down lactose in breast milk or formula. This form of lactose intolerance results in severe diarrhea. If affected infants are not given a lactose-free infant formula, they may develop severe dehydration and weight loss.  Lactose intolerance in adulthood is caused by reduced production of lactase after infancy (lactase nonpersistence). If individuals with lactose intolerance consume lactose-containing dairy products, they may experience abdominal pain, bloating, flatulence, nausea, and diarrhea beginning 30 minutes to 2 hours later.  Most people with lactase nonpersistence retain some lactase activity and can include varying amounts of lactose in their diets without experiencing symptoms. Often, affected individuals have difficulty digesting fresh milk but can eat certain dairy products such as cheese or yogurt without discomfort. These foods are made using fermentation processes that break down much of the lactose in milk.

Topic: lactose intolerance
Question: How many people are affected by lactose intolerance ?
Answer: Lactose intolerance in infancy resulting from congenital lactase deficiency is a rare disorder. Its incidence is unknown. This condition is most common in Finland, where it affects an estimated 1 in 60,000 newborns.  Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy. Lactose intolerance in adulthood is most prevalent in people of East Asian descent, affecting more than 90 percent of adults in some of these communities. Lactose intolerance is also very common in people of West African, Arab, Jewish, Greek, and Italian descent.  The prevalence of lactose intolerance is lowest in populations with a long history of dependence on unfermented milk products as an important food source. For example, only about 5 percent of people of Northern European descent are lactose intolerant.
