Question:
How many people are affected by nonsyndromic paraganglioma ?

Answer:
It is estimated that the prevalence of pheochromocytoma is 1 in 500,000 people, and the prevalence of other paragangliomas is 1 in 1 million people. These statistics include syndromic and nonsyndromic paraganglioma and pheochromocytoma.
Question:
What are the genetic changes related to nonsyndromic paraganglioma ?

Answer:
The VHL, RET, SDHB, and SDHD genes can be mutated in both syndromic and nonsyndromic forms of paraganglioma and pheochromocytoma. Mutations in at least three additional genes, TMEM127, SDHA, and KIF1B, have been identified in people with the nonsyndromic form of these conditions. Gene mutations increase the risk of developing paraganglioma or pheochromocytoma by affecting control of cell growth and division.  Mutations in the VHL, SDHA, SDHB, and SDHD genes increase the risk of developing nonsyndromic paraganglioma or pheochromocytoma. The protein produced from the VHL gene helps break down other, unneeded proteins, including a protein called HIF that stimulates cell division and blood vessel formation under certain cellular conditions. The proteins produced from the SDHA, SHDB, and SDHD genes are each pieces (subunits) of an enzyme that is important for energy production in the cell. This enzyme also plays a role in the breakdown of the HIF protein. Mutations in the VHL, SDHA, SDHB, and SDHD genes stabilize the HIF protein, causing it to build up in cells. Excess HIF protein stimulates cells to divide and triggers the production of blood vessels when they are not needed. Rapid and uncontrolled cell division, along with the formation of new blood vessels, can lead to the development of tumors.  Mutations in the RET gene have been found in nonsyndromic pheochromocytoma in addition to a pheochromocytoma-predisposing syndrome. The protein produced from the RET gene is involved in signaling within cells that can stimulate cell division or maturation. Mutations in the RET gene overactivate the protein's signaling function, which can trigger cell growth and division in the absence of signals from outside the cell. This unchecked cell division can lead to the formation of tumors in the adrenal glands.  Mutations in the TMEM127 gene have been identified most commonly in people with nonsyndromic pheochromocytoma and are rarely seen in people with other paraganglioma. The TMEM127 protein normally controls a signaling pathway that induces cell growth and survival. Studies suggest that mutations in the TMEM127 gene lead to abnormal activation of cell growth, which may cause tumor formation.  Mutations in the KIF1B gene have been reported in nonsyndromic pheochromocytoma. Studies suggest that these mutations impair the function of the KIF1B protein, which normally triggers cells to self-destruct in a process called apoptosis. When apoptosis is impaired, cells grow and divide too quickly or in an uncontrolled way, potentially leading to tumor formation.  Many people with nonsyndromic paraganglioma or pheochromocytoma do not have a mutation in any of the genes associated with the conditions. It is likely that other, unidentified genes also predispose to development of paraganglioma or pheochromocytoma.
Question:
Is nonsyndromic paraganglioma inherited ?

Answer:
Nonsyndromic paraganglioma can be inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase the risk of developing a paraganglioma or pheochromocytoma. People with mutations in the gene inherit an increased risk of this condition, not the condition itself. Not all people with this condition have a mutation in the gene, and not all people with a gene mutation will develop the disorder.  Most cases of nonsyndromic paraganglioma and pheochromocytoma are considered sporadic, which means the tumors occur in people with no history of the disorder in their family.

Question:
What is (are) hereditary leiomyomatosis and renal cell cancer ?

Answer:
Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a disorder in which affected individuals tend to develop benign tumors containing smooth muscle tissue (leiomyomas) in the skin and, in females, the uterus. This condition also increases the risk of kidney cancer.  In this disorder, growths on the skin (cutaneous leiomyomas) typically develop in the third decade of life. Most of these growths arise from the tiny muscles around the hair follicles that cause "goosebumps". They appear as bumps or nodules on the trunk, arms, legs, and occasionally on the face. Cutaneous leiomyomas may be the same color as the surrounding skin, or they may be darker. Some affected individuals have no cutaneous leiomyomas or only a few, but the growths tend to increase in size and number over time. Cutaneous leiomyomas are often more sensitive than the surrounding skin to cold or light touch, and may be painful.  Most women with HLRCC also develop uterine leiomyomas (fibroids). While uterine fibroids are very common in the general population, women with HLRCC tend to have numerous large fibroids that appear earlier than in the general population.  Approximately 10 percent to 16 percent of people with HLRCC develop a type of kidney cancer called renal cell cancer. The signs and symptoms of renal cell cancer may include lower back pain, blood in the urine, or a mass in the kidney that can be felt upon physical examination. Some people with renal cell cancer have no symptoms until the disease is advanced. The average age at which people with HLRCC are diagnosed with kidney cancer is in their forties.  This disorder, especially if it appears in individuals or families without renal cell cancer, is also sometimes called multiple cutaneous leiomyomatosis (MCL) or multiple cutaneous and uterine leiomyomatosis (MCUL).
Question:
How many people are affected by hereditary leiomyomatosis and renal cell cancer ?

Answer:
HLRCC has been reported in approximately 100 families worldwide. Its prevalence is unknown.
Question:
What are the genetic changes related to hereditary leiomyomatosis and renal cell cancer ?

Answer:
Mutations in the FH gene cause hereditary leiomyomatosis and renal cell cancer. The FH gene provides instructions for making an enzyme called fumarase (also known as fumarate hydratase). This enzyme participates in an important series of reactions known as the citric acid cycle or Krebs cycle, which allows cells to use oxygen and generate energy. Specifically, fumarase helps convert a molecule called fumarate to a molecule called malate.  People with HLRCC are born with one mutated copy of the FH gene in each cell. The second copy of the FH gene in certain cells may also acquire mutations as a result of environmental factors such as ultraviolet radiation from the sun or a mistake that occurs as DNA copies itself during cell division.  FH gene mutations may interfere with the enzyme's role in the citric acid cycle, resulting in a buildup of fumarate. Researchers believe that the excess fumarate may interfere with the regulation of oxygen levels in the cell. Chronic oxygen deficiency (hypoxia) in cells with two mutated copies of the FH gene may encourage tumor formation and result in the tendency to develop leiomyomas and renal cell cancer.
Question:
Is hereditary leiomyomatosis and renal cell cancer 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.

Question:
What is (are) factor V deficiency ?

Answer:
Factor V deficiency is a rare bleeding disorder. The signs and symptoms of this condition can begin at any age, although the most severe cases are apparent in childhood. Factor V deficiency commonly causes nosebleeds; easy bruising; bleeding under the skin; bleeding of the gums; and prolonged or excessive bleeding following surgery, trauma, or childbirth. Women with factor V deficiency can have heavy or prolonged menstrual bleeding (menorrhagia). Bleeding into joint spaces (hemarthrosis) can also occur, although it is rare. Severely affected individuals have an increased risk of bleeding inside the skull (intracranial hemorrhage), in the lungs (pulmonary hemorrhage), or in the gastrointestinal tract, which can be life-threatening.
Question:
How many people are affected by factor V deficiency ?

Answer:
Factor V deficiency affects an estimated 1 in 1 million people. This condition is more common in countries such as Iran and southern India, where it occurs up to ten times more frequently than in western countries.
Question:
What are the genetic changes related to factor V deficiency ?

Answer:
Factor V deficiency is usually caused by mutations in the F5 gene, which provides instructions for making a protein called coagulation factor V. This protein plays a critical role in the coagulation system, which is a series of chemical reactions that forms blood clots in response to injury. F5 gene mutations that cause factor V deficiency prevent the production of functional coagulation factor V or severely reduce the amount of the protein in the bloodstream. People with this condition typically have less than 10 percent of normal levels of coagulation factor V in their blood; the most severely affected individuals have less than 1 percent. A reduced amount of functional coagulation factor V prevents blood from clotting normally, causing episodes of abnormal bleeding that can be severe.  Very rarely, a form of factor V deficiency is caused by abnormal antibodies that recognize coagulation factor V. Antibodies normally attach (bind) to specific foreign particles and germs, marking them for destruction, but the antibodies in this form of factor V deficiency attack a normal human protein, leading to its inactivation. These cases are called acquired factor V deficiency and usually occur in individuals who have been treated with substances that stimulate the production of anti-factor V antibodies, such as bovine thrombin used during surgical procedures. There is no known genetic cause for this form of the condition.
Question:
Is factor V deficiency inherited ?

Answer:
Factor V deficiency is inherited in an autosomal recessive pattern, which means both copies of the F5 gene in each cell have mutations. Individuals with a mutation in a single copy of the F5 gene have a reduced amount of coagulation factor V in their blood and can have mild bleeding problems, although most have no related health effects.

Question:
What is (are) glucose-6-phosphate dehydrogenase deficiency ?

Answer:
Glucose-6-phosphate dehydrogenase deficiency is a genetic disorder that occurs most often in males. This condition mainly affects red blood cells, which carry oxygen from the lungs to tissues throughout the body. In affected individuals, a defect in an enzyme called glucose-6-phosphate dehydrogenase causes red blood cells to break down prematurely. This destruction of red blood cells is called hemolysis.  The most common medical problem associated with glucose-6-phosphate dehydrogenase deficiency is hemolytic anemia, which occurs when red blood cells are destroyed faster than the body can replace them. This type of anemia leads to paleness, yellowing of the skin and whites of the eyes (jaundice), dark urine, fatigue, shortness of breath, and a rapid heart rate. In people with glucose-6-dehydrogenase deficiency, hemolytic anemia is most often triggered by bacterial or viral infections or by certain drugs (such as some antibiotics and medications used to treat malaria). Hemolytic anemia can also occur after eating fava beans or inhaling pollen from fava plants (a reaction called favism).  Glucose-6-dehydrogenase deficiency is also a significant cause of mild to severe jaundice in newborns. Many people with this disorder, however, never experience any signs or symptoms.
Question:
How many people are affected by glucose-6-phosphate dehydrogenase deficiency ?

Answer:
An estimated 400 million people worldwide have glucose-6-phosphate dehydrogenase deficiency. This condition occurs most frequently in certain parts of Africa, Asia, and the Mediterranean. It affects about 1 in 10 African American males in the United States.
Question:
What are the genetic changes related to glucose-6-phosphate dehydrogenase deficiency ?

Answer:
Mutations in the G6PD gene cause glucose-6-phosphate dehydrogenase deficiency.  The G6PD gene provides instructions for making an enzyme called glucose-6-phosphate dehydrogenase. This enzyme is involved in the normal processing of carbohydrates. It also protects red blood cells from the effects of potentially harmful molecules called reactive oxygen species. Reactive oxygen species are byproducts of normal cellular functions. Chemical reactions involving glucose-6-phosphate dehydrogenase produce compounds that prevent reactive oxygen species from building up to toxic levels within red blood cells.  If mutations in the G6PD gene reduce the amount of glucose-6-phosphate dehydrogenase or alter its structure, this enzyme can no longer play its protective role. As a result, reactive oxygen species can accumulate and damage red blood cells. Factors such as infections, certain drugs, or ingesting fava beans can increase the levels of reactive oxygen species, causing red blood cells to be destroyed faster than the body can replace them. A reduction in the amount of red blood cells causes the signs and symptoms of hemolytic anemia.  Researchers believe that carriers of a G6PD mutation may be partially protected against malaria, an infectious disease carried by a certain type of mosquito. A reduction in the amount of functional glucose-6-dehydrogenase appears to make it more difficult for this parasite to invade red blood cells. Glucose-6-phosphate dehydrogenase deficiency occurs most frequently in areas of the world where malaria is common.
Question:
Is glucose-6-phosphate dehydrogenase deficiency inherited ?

Answer:
This condition is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

Question:
What is (are) Liddle syndrome ?

Answer:
Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.  In addition to hypertension, affected individuals can have low levels of potassium in the blood (hypokalemia). Signs and symptoms of hypokalemia include muscle weakness or pain, fatigue, constipation, or heart palpitations. The shortage of potassium can also raise the pH of the blood, a condition known as metabolic alkalosis.
Question:
How many people are affected by Liddle syndrome ?

Answer:
Liddle syndrome is a rare condition, although its prevalence is unknown. The condition has been found in populations worldwide.
Question:
What are the genetic changes related to Liddle syndrome ?

Answer:
Liddle syndrome is caused by mutations in the SCNN1B or SCNN1G gene. Each of these genes provides instructions for making a piece (subunit) of a protein complex called the epithelial sodium channel (ENaC). These channels are found at the surface of certain cells called epithelial cells in many tissues of the body, including the kidneys, where the channels transport sodium into cells.  In the kidney, ENaC channels open in response to signals that sodium levels in the blood are too low, which allows sodium to flow into cells. From the kidney cells, this sodium is returned to the bloodstream (a process called reabsorption) rather than being removed from the body in urine.  Mutations in the SCNN1B or SCNN1G gene change the structure of the respective ENaC subunit. The changes alter a region of the subunit that is involved in signaling for its breakdown (degradation) when it is no longer needed. As a result of the mutations, the subunit proteins are not degraded, and more ENaC channels remain at the cell surface. The increase in channels at the cell surface abnormally increases the reabsorption of sodium (followed by water), which leads to hypertension. Reabsorption of sodium into the blood is linked with removal of potassium from the blood, so excess sodium reabsorption leads to hypokalemia.
Question:
Is Liddle syndrome 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.

Question:
What is (are) 3-beta-hydroxysteroid dehydrogenase deficiency ?

Answer:
3-beta ()-hydroxysteroid dehydrogenase (HSD) deficiency is an inherited disorder that affects hormone-producing glands including the gonads (ovaries in females and testes in males) and the adrenal glands. The gonads direct sexual development before birth and during puberty. The adrenal glands, which are located on top of the kidneys, regulate the production of certain hormones and control salt levels in the body. People with 3-HSD deficiency lack many of the hormones that are made in these glands. 3-HSD deficiency is one of a group of disorders known as congenital adrenal hyperplasias that impair hormone production and disrupt sexual development and maturation.  There are three types of 3-HSD deficiency: the salt-wasting, non-salt-wasting, and non-classic types. In the salt-wasting type, hormone production is extremely low. Individuals with this type lose large amounts of sodium in their urine, which can be life-threatening. Individuals affected with the salt-wasting type are usually diagnosed soon after birth due to complications related to a lack of salt reabsorption, including dehydration, poor feeding, and vomiting. People with the non-salt-wasting type of 3-HSD deficiency produce enough hormone to allow sodium reabsorption in the kidneys. Individuals with the non-classic type have the mildest symptoms and do not experience salt wasting.  In males with any type of 3-HSD deficiency, problems with male sex hormones lead to abnormalities of the external genitalia. These abnormalities range from having the opening of the urethra on the underside of the penis (hypospadias) to having external genitalia that do not look clearly male or female (ambiguous genitalia). The severity of the genital abnormality does not consistently depend on the type of the condition. Because of the hormone dysfunction in the testes, males with 3-HSD deficiency are frequently unable to have biological children (infertile).  Females with 3-HSD deficiency may have slight abnormalities of the external genitalia at birth. Females affected with the non-salt-wasting or non-classic types are typically not diagnosed until mid-childhood or puberty, when they may experience irregular menstruation, premature pubic hair growth, and excessive body hair growth (hirsutism). Females with 3-HSD deficiency have difficulty conceiving a child (impaired fertility).
Question:
How many people are affected by 3-beta-hydroxysteroid dehydrogenase deficiency ?

Answer:
The exact prevalence of 3-HSD deficiency is unknown. At least 60 affected individuals have been reported.
Question:
What are the genetic changes related to 3-beta-hydroxysteroid dehydrogenase deficiency ?

Answer:
Mutations in the HSD3B2 gene cause 3-HSD deficiency. The HSD3B2 gene provides instructions for making the 3-HSD enzyme. This enzyme is found in the gonads and adrenal glands. The 3-HSD enzyme is involved in the production of many hormones, including cortisol, aldosterone, androgens, and estrogen. Cortisol has numerous functions such as maintaining energy and blood sugar levels, protecting the body from stress, and suppressing inflammation. Aldosterone is sometimes called the salt-retaining hormone because it regulates the amount of salt retained by the kidney. The retention of salt affects fluid levels and blood pressure. Androgens and estrogen are essential for normal sexual development and reproduction.  3-HSD deficiency is caused by a deficiency (shortage) of the 3-HSD enzyme. The amount of functional 3-HSD enzyme determines whether a person will have the salt-wasting or non-salt-wasting type of the disorder. Individuals with the salt-wasting type have HSD3B2 gene mutations that result in the production of very little or no enzyme. People with the non-salt-wasting type of this condition have HSD3B2 gene mutations that allow the production of some functional enzyme, although in reduced amounts.
Question:
Is 3-beta-hydroxysteroid dehydrogenase deficiency 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.
