How many people are affected by Duane-radial ray syndrome ?
Duane-radial ray syndrome is a rare condition whose prevalence is unknown. Only a few affected families have been reported worldwide. + GHR + Duane-radial ray syndrome
What are the genetic changes related to Duane-radial ray syndrome ?
Duane-radial ray syndrome results from mutations in the SALL4 gene. This gene is part of a group of genes called the SALL family. SALL genes provide instructions for making proteins that are involved in the formation of tissues and organs before birth. The proteins produced from these genes act as transcription factors, which means they attach (bind) to specific regions of DNA and help control the activity of particular genes. The exact function of the SALL4 protein is unclear, although it appears to be important for the normal development of the eyes, heart, and limbs.  Mutations in the SALL4 gene prevent cells from making any functional protein from one copy of the gene. It is unclear how a reduction in the amount of the SALL4 protein leads to Duane anomaly, radial ray malformations, and the other features of Duane-radial ray syndrome and similar conditions. + GHR + Duane-radial ray syndrome
Is Duane-radial ray syndrome inherited ?
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered SALL4 gene in each cell is sufficient to cause the disorder. In many cases, an affected person inherits a mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family. + GHR + Duane-radial ray syndrome

What is (are) ornithine translocase deficiency ?
Ornithine translocase deficiency is an inherited disorder that causes ammonia to accumulate in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if the levels become too high. The nervous system is especially sensitive to the effects of excess ammonia.  Ornithine translocase deficiency varies widely in its severity and age of onset. An infant with ornithine translocase deficiency may be lacking in energy (lethargic) or refuse to eat, or have poorly controlled breathing or body temperature. Some babies with this disorder may experience seizures or unusual body movements, or go into a coma. Episodes of illness may coincide with the introduction of high-protein formulas or solid foods into the diet.  In most affected individuals, signs and symptoms of ornithine translocase deficiency do not appear until later in life. Later-onset forms of ornithine translocase deficiency are usually less severe than the infantile form. Some people with later-onset ornithine translocase deficiency cannot tolerate high-protein foods, such as meat. Occasionally, high-protein meals or stress caused by illness or periods without food (fasting) may cause ammonia to accumulate more quickly in the blood. This rapid increase of ammonia may lead to episodes of vomiting, lack of energy (lethargy), problems with coordination (ataxia), confusion, or blurred vision. Complications of ornithine translocase deficiency may include developmental delay, learning disabilities, and stiffness caused by abnormal tensing of the muscles (spasticity). + GHR + ornithine translocase deficiency
How many people are affected by ornithine translocase deficiency ?
Ornithine translocase deficiency is a very rare disorder. Fewer than 100 affected individuals have been reported worldwide. + GHR + ornithine translocase deficiency
What are the genetic changes related to ornithine translocase deficiency ?
Mutations in the SLC25A15 gene cause ornithine translocase deficiency.  Ornithine translocase deficiency belongs to a class of genetic diseases called urea cycle disorders. The urea cycle is a sequence of reactions that occurs in liver cells. This cycle processes excess nitrogen, generated when protein is used by the body, to make a compound called urea that is excreted by the kidneys.  The SLC25A15 gene provides instructions for making a protein called a mitochondrial ornithine transporter. This protein is needed to move a molecule called ornithine within the mitochondria (the energy-producing centers in cells). Specifically, this protein transports ornithine across the inner membrane of mitochondria to the region called the mitochondrial matrix, where it participates in the urea cycle.  Mutations in the SLC25A15 gene result in a mitochondrial ornithine transporter that is unstable or the wrong shape, and which cannot bring ornithine to the mitochondrial matrix. This failure of ornithine transport causes an interruption of the urea cycle and the accumulation of ammonia, resulting in the signs and symptoms of ornithine translocase deficiency. + GHR + ornithine translocase deficiency
Is ornithine translocase 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. + GHR + ornithine translocase deficiency

What is (are) Klippel-Trenaunay syndrome ?
Klippel-Trenaunay syndrome is a condition that affects the development of blood vessels, soft tissues, and bones. The disorder has three characteristic features: a red birthmark called a port-wine stain, abnormal overgrowth of soft tissues and bones, and vein malformations.  Most people with Klippel-Trenaunay syndrome are born with a port-wine stain. This type of birthmark is caused by swelling of small blood vessels near the surface of the skin. Port-wine stains are typically flat and can vary from pale pink to deep maroon in color. In people with Klippel-Trenaunay syndrome, the port-wine stain usually covers part of one limb. The affected area may become lighter or darker with age. Occasionally, port-wine stains develop small red blisters that break open and bleed easily.  Klippel-Trenaunay syndrome is also associated with overgrowth of bones and soft tissues beginning in infancy. Usually this abnormal growth is limited to one limb, most often one leg. However, overgrowth can also affect the arms or, rarely, the trunk. The abnormal growth can cause pain, a feeling of heaviness, and reduced movement in the affected area. If the overgrowth causes one leg to be longer than the other, it can also lead to problems with walking.  Malformations of veins are the third major feature of Klippel-Trenaunay syndrome. These abnormalities include varicose veins, which are swollen and twisted veins near the surface of the skin that often cause pain. Varicose veins usually occur on the sides of the upper legs and calves. Veins deep in the limbs can also be abnormal in people with Klippel-Trenaunay syndrome. Malformations of deep veins increase the risk of a type of clot called a deep vein thrombosis (DVT). If a DVT travels through the bloodstream and lodges in the lungs, it can cause a life-threatening clot known as a pulmonary embolism (PE).  Complications of Klippel-Trenaunay syndrome can include a type of skin infection called cellulitis, swelling caused by a buildup of fluid (lymphedema), and internal bleeding from abnormal blood vessels. Less commonly, this condition is also associated with fusion of certain fingers or toes (syndactyly) or the presence of extra digits (polydactyly). + GHR + Klippel-Trenaunay syndrome
How many people are affected by Klippel-Trenaunay syndrome ?
Klippel-Trenaunay syndrome is estimated to affect at least 1 in 100,000 people worldwide. + GHR + Klippel-Trenaunay syndrome
What are the genetic changes related to Klippel-Trenaunay syndrome ?
The cause of Klippel-Trenaunay syndrome is unknown. Researchers suspect that the condition may result from changes in one or more genes that regulate the growth of blood vessels during embryonic development. However, no associated genes have been identified. It is also unclear how blood vessel malformations are related to the overgrowth of bones and soft tissues. + GHR + Klippel-Trenaunay syndrome
Is Klippel-Trenaunay syndrome inherited ?
Klippel-Trenaunay syndrome is almost always sporadic, which means that it occurs in people with no history of the disorder in their family. Studies suggest that the condition may result from gene mutations that are not inherited. These genetic changes, which are called somatic mutations, probably occur very early in development and are present only in certain cells. Somatic mutations could explain why the signs and symptoms of Klippel-Trenaunay syndrome are often limited to specific areas of the body. However, it is unclear whether somatic mutations are responsible for this condition because no associated genes have been found. + GHR + Klippel-Trenaunay syndrome

What is (are) Wilson disease ?
Wilson disease is an inherited disorder in which excessive amounts of copper accumulate in the body, particularly in the liver, brain, and eyes. The signs and symptoms of Wilson disease usually first appear between the ages of 6 and 45, but they most often begin during the teenage years. The features of this condition include a combination of liver disease and neurological and psychiatric problems.  Liver disease is typically the initial feature of Wilson disease in affected children and young adults; individuals diagnosed at an older age usually do not have symptoms of liver problems, although they may have very mild liver disease. The signs and symptoms of liver disease include yellowing of the skin or whites of the eyes (jaundice), fatigue, loss of appetite, and abdominal swelling.  Nervous system or psychiatric problems are often the initial features in individuals diagnosed in adulthood and commonly occur in young adults with Wilson disease. Signs and symptoms of these problems can include clumsiness, tremors, difficulty walking, speech problems, impaired thinking ability, depression, anxiety, and mood swings.  In many individuals with Wilson disease, copper deposits in the front surface of the eye (the cornea) form a green-to-brownish ring, called the Kayser-Fleischer ring, that surrounds the colored part of the eye. Abnormalities in eye movements, such as a restricted ability to gaze upwards, may also occur. + GHR + Wilson disease
How many people are affected by Wilson disease ?
Wilson disease is a rare disorder that affects approximately 1 in 30,000 individuals. + GHR + Wilson disease
What are the genetic changes related to Wilson disease ?
Wilson disease is caused by mutations in the ATP7B gene. This gene provides instructions for making a protein called copper-transporting ATPase 2, which plays a role in the transport of copper from the liver to other parts of the body. Copper is necessary for many cellular functions, but it is toxic when present in excessive amounts. The copper-transporting ATPase 2 protein is particularly important for the elimination of excess copper from the body. Mutations in the ATP7B gene prevent the transport protein from functioning properly. With a shortage of functional protein, excess copper is not removed from the body. As a result, copper accumulates to toxic levels that can damage tissues and organs, particularly the liver and brain.  Research indicates that a normal variation in the PRNP gene may modify the course of Wilson disease. The PRNP gene provides instructions for making prion protein, which is active in the brain and other tissues and appears to be involved in transporting copper. Studies have focused on the effects of a PRNP gene variation that affects position 129 of the prion protein. At this position, people can have either the protein building block (amino acid) methionine or the amino acid valine. Among people who have mutations in the ATP7B gene, it appears that having methionine instead of valine at position 129 of the prion protein is associated with delayed onset of symptoms and an increased occurrence of neurological symptoms, particularly tremors. Larger studies are needed, however, before the effects of this PRNP gene variation on Wilson disease can be established. + GHR + Wilson disease

What is (are) neurohypophyseal diabetes insipidus ?
Neurohypophyseal diabetes insipidus is a disorder of water balance. The body normally balances fluid intake with the excretion of fluid in urine. However, people with neurohypophyseal diabetes insipidus produce too much urine (polyuria), which causes them to be excessively thirsty (polydipsia). Affected people need to urinate frequently, which can disrupt daily activities and sleep.  People with neurohypophyseal diabetes insipidus can quickly become dehydrated if they do not drink enough water. Dehydration can lead to constipation and dry skin. If the disorder is not treated, more serious complications of dehydration can occur. These include confusion, low blood pressure, seizures, and coma.  Neurohypophyseal diabetes insipidus can be either acquired or familial. The acquired form is brought on by injuries, tumors, and other factors, and can occur at any time during life. The familial form is caused by genetic mutations; its signs and symptoms usually become apparent in childhood and worsen over time.  Neurohypophyseal diabetes insipidus should not be confused with diabetes mellitus, which is much more common. Diabetes mellitus is characterized by high blood sugar levels resulting from a shortage of the hormone insulin or an insensitivity to this hormone. Although neurohypophyseal diabetes insipidus and diabetes mellitus have some features in common, they are separate disorders with different causes. + GHR + neurohypophyseal diabetes insipidus
How many people are affected by neurohypophyseal diabetes insipidus ?
Neurohypophyseal diabetes insipidus is thought to be rare, although its exact incidence is unknown. The acquired form occurs much more frequently than the familial form. + GHR + neurohypophyseal diabetes insipidus
What are the genetic changes related to neurohypophyseal diabetes insipidus ?
The familial form of neurohypophyseal diabetes insipidus is caused by mutations in the AVP gene. This gene provides instructions for making a hormone called vasopressin or antidiuretic hormone (ADH). This hormone, which is produced and stored in the brain, helps control the body's water balance.  The kidneys filter the blood to remove waste and excess fluid, which are stored in the bladder as urine. ADH controls the balance between fluid intake and urine excretion. Normally, when a person's fluid intake is low or when a lot of fluid is lost (for example, through sweating), the brain releases more ADH into the bloodstream. High levels of this hormone direct the kidneys to reabsorb more water and to make less urine. When fluid intake is adequate, the brain releases less ADH. Lower levels of this hormone cause the kidneys to reabsorb less water and to make more urine.  Mutations in the AVP gene result in progressive damage to the brain cells where ADH is produced. These cells ultimately die, causing a shortage of ADH. Without this hormone, the kidneys do not reabsorb water as they should, and the body makes excessive amounts of urine. These problems with water balance are characteristic of neurohypophyseal diabetes insipidus.  The acquired form of neurohypophyseal diabetes insipidus results when the areas of the brain that produce or store ADH are damaged by head injuries, brain tumors, brain surgery, certain diseases and infections, or bleeding in the brain. A loss of ADH disrupts the body's water balance, leading to excessive urine production and the other features of the disorder.  In 30 to 50 percent of all cases of neurohypophyseal diabetes insipidus, the cause of the disorder is unknown. Studies suggest that some of these cases may have an autoimmune basis. Autoimmune disorders occur when the immune system malfunctions and attacks the body's own tissues and organs. For unknown reasons, in some people with neurohypophyseal diabetes insipidus the immune system appears to damage the brain cells that normally produce ADH. + GHR + neurohypophyseal diabetes insipidus
Is neurohypophyseal diabetes insipidus inherited ?
Familial neurohypophyseal diabetes insipidus is almost always inherited in an autosomal dominant pattern, which means one copy of the altered AVP gene in each cell is sufficient to cause the disorder.  In a few affected families, the condition has had an autosomal recessive pattern of inheritance. Autosomal recessive inheritance means that 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. + GHR + neurohypophyseal diabetes insipidus

What is (are) globozoospermia ?
Globozoospermia is a condition that affects only males. It is characterized by abnormal sperm and leads to an inability to father biological children (infertility).  Normal sperm cells have an oval-shaped head with a cap-like covering called the acrosome. The acrosome contains enzymes that break down the outer membrane of an egg cell, allowing the sperm to fertilize the egg. The sperm cells of males with globozoospermia, however, have a round head and no acrosome. The abnormal sperm are unable to fertilize an egg cell, leading to infertility. + GHR + globozoospermia
How many people are affected by globozoospermia ?
Globozoospermia is a rare condition that is estimated to affect 1 in 65,000 men. It is most common in North Africa, where it accounts for approximately 1 in 100 cases of male infertility. + GHR + globozoospermia
What are the genetic changes related to globozoospermia ?
Globozoospermia is most commonly caused by mutations in the DPY19L2 gene, which are found in about 70 percent of men with this condition. Mutations in other genes likely also cause globozoospermia.  The DPY19L2 gene provides instructions for making a protein that is found in developing sperm cells. The DPY19L2 protein is involved in the development of the acrosome and elongation of the sperm head, which are integral steps in sperm cell maturation. Mutations in the DPY19L2 gene result in a loss of functional DPY19L2 protein. As a result, sperm cells have no acrosome and do not elongate properly. Without an acrosome, the abnormal sperm are unable to get through the outer membrane of an egg cell to fertilize it, leading to infertility in affected men. Researchers have described other characteristics of the abnormal sperm cells that make fertilization of an egg cell difficult, although it is not clear how changes in the DPY19L2 gene are involved in development of these characteristics. + GHR + globozoospermia
Is globozoospermia inherited ?

What is (are) Meckel syndrome ?
Meckel syndrome is a disorder with severe signs and symptoms that affect many parts of the body. The most common features are enlarged kidneys with numerous fluid-filled cysts; an occipital encephalocele, which is a sac-like protrusion of the brain through an opening at the back of the skull; and the presence of extra fingers and toes (polydactyly). Most affected individuals also have a buildup of scar tissue (fibrosis) in the liver.  Other signs and symptoms of Meckel syndrome vary widely among affected individuals. Numerous abnormalities of the brain and spinal cord (central nervous system) have been reported in people with Meckel syndrome, including a group of birth defects known as neural tube defects. These defects occur when a structure called the neural tube, a layer of cells that ultimately develops into the brain and spinal cord, fails to close completely during the first few weeks of embryonic development. Meckel syndrome can also cause problems with development of the eyes and other facial features, heart, bones, urinary system, and genitalia.  Because of their serious health problems, most individuals with Meckel syndrome die before or shortly after birth. Most often, affected infants die of respiratory problems or kidney failure. + GHR + Meckel syndrome
