What is (are) warfarin resistance ? 
 Warfarin resistance is a condition in which individuals have a high tolerance for the drug warfarin. Warfarin is an anticoagulant, which means that it thins the blood, preventing blood clots from forming. Warfarin is often prescribed to prevent blood clots in people with heart valve disease who have replacement heart valves, people with an irregular heart beat (atrial fibrillation), or those with a history of heart attack, stroke, or a prior blood clot in the deep veins of the arms or legs (deep vein thrombosis).  There are two types of warfarin resistance: incomplete and complete. Those with incomplete warfarin resistance can achieve the benefits of warfarin treatment with a high dose of warfarin. Individuals with complete warfarin resistance do not respond to warfarin treatment, no matter how high the dose. If people with warfarin resistance require treatment with warfarin and take the average dose, they will remain at risk of developing a potentially harmful blood clot.  Both types of warfarin resistance are related to how the body processes warfarin. In some people with warfarin resistance, their blood clotting process does not react effectively to the drug. Others with this resistance rapidly break down (metabolize) warfarin, so the medication is quickly processed by their bodies; these individuals are classified as "fast metabolizers" or "rapid metabolizers" of warfarin. The severity of these abnormal processes determines whether the warfarin resistance is complete or incomplete.  Warfarin resistance does not appear to cause any health problems other than those associated with warfarin drug treatment.
How many people are affected by warfarin resistance ? 
 Warfarin resistance is thought to be a rare condition, although its prevalence is unknown.
What are the genetic changes related to warfarin resistance ? 
 Many genes are involved in the metabolism of warfarin and in determining the drug's effects in the body. Certain common changes (polymorphisms) in the VKORC1 gene account for 20 percent of the variation in warfarin metabolism due to genetic factors. Polymorphisms in other genes, some of which have not been identified, have a smaller effect on warfarin metabolism.  The VKORC1 gene provides instructions for making a vitamin K epoxide reductase enzyme. The VKORC1 enzyme helps turn on (activate) clotting proteins in the pathway that forms blood clots. Warfarin prevents (inhibits) the action of VKORC1 by binding to the complex and preventing it from binding to and activating the clotting proteins, stopping clot formation. Certain VKORC1 gene polymorphisms lead to the formation of a VKORC1 enzyme with a decreased ability to bind to warfarin. This reduction in warfarin binding causes incomplete warfarin resistance and results in more warfarin being needed to inhibit the VKORC1 enzyme and stop the clotting process. If no warfarin can bind to the VKORC1 enzyme, the result is complete warfarin resistance.  While changes in specific genes affect how the body reacts to warfarin, many other factors, including gender, age, weight, diet, and other medications, also play a role in the body's interaction with this drug.
Is warfarin resistance inherited ? 
 The polymorphisms associated with this condition are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to result in warfarin resistance. However, different polymorphisms affect the activity of warfarin to varying degrees. Additionally, people who have more than one polymorphism in a gene or polymorphisms in multiple genes associated with warfarin resistance have a higher tolerance for the drug's effect or are able to process the drug more quickly.

What is (are) Feingold syndrome ? 
 Feingold syndrome is a disorder that affects many parts of the body. The signs and symptoms of this condition vary among affected individuals, even among members of the same family.  Individuals with Feingold syndrome have characteristic abnormalities of their fingers and toes. Almost all people with this condition have a specific hand abnormality called brachymesophalangy, which refers to shortening of the second and fifth fingers. Other common abnormalities include fifth fingers that curve inward (clinodactyly), underdeveloped thumbs (thumb hypoplasia), and fusion (syndactyly) of the second and third toes or the fourth and fifth toes.  People with Feingold syndrome are frequently born with a blockage in part of their digestive system called gastrointestinal atresia. In most cases, the blockage occurs in the esophagus (esophageal atresia) or in part of the small intestine (duodenal atresia). Additional common features of Feingold syndrome include an unusually small head size (microcephaly), a small jaw (micrognathia), a narrow opening of the eyelids (short palpebral fissures), and mild to moderate learning disability. Less often, affected individuals have hearing loss, impaired growth, and kidney and heart abnormalities.
How many people are affected by Feingold syndrome ? 
 Feingold syndrome appears to be a rare condition, although its exact prevalence is unknown.
What are the genetic changes related to Feingold syndrome ? 
 Mutations in the MYCN gene cause Feingold syndrome. This gene provides instructions for making a protein that plays an important role in the formation of tissues and organs during embryonic development. Studies in animals suggest that this protein is necessary for normal development of the limbs, heart, kidneys, nervous system, digestive system, and lungs. The MYCN protein regulates the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, this protein is called a transcription factor.  Mutations in the MYCN gene that cause Feingold syndrome prevent one copy of the gene in each cell from producing any functional MYCN protein. As a result, only half the normal amount of this protein is available to control the activity of specific genes during embryonic development. It remains unclear how a reduced amount of the MYCN protein causes the specific features of Feingold syndrome.
Is Feingold syndrome inherited ? 
 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.

What is (are) hypercholesterolemia ? 
 Hypercholesterolemia is a condition characterized by very high levels of cholesterol in the blood. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals (particularly egg yolks, meat, poultry, fish, and dairy products). The body needs this substance to build cell membranes, make certain hormones, and produce compounds that aid in fat digestion. Too much cholesterol, however, increases a person's risk of developing heart disease.  People with hypercholesterolemia have a high risk of developing a form of heart disease called coronary artery disease. This condition occurs when excess cholesterol in the bloodstream is deposited in the walls of blood vessels, particularly in the arteries that supply blood to the heart (coronary arteries). The abnormal buildup of cholesterol forms clumps (plaque) that narrow and harden artery walls. As the clumps get bigger, they can clog the arteries and restrict the flow of blood to the heart. The buildup of plaque in coronary arteries causes a form of chest pain called angina and greatly increases a person's risk of having a heart attack.  Inherited forms of hypercholesterolemia can also cause health problems related to the buildup of excess cholesterol in other tissues. If cholesterol accumulates in tendons, it causes characteristic growths called tendon xanthomas. These growths most often affect the Achilles tendons and tendons in the hands and fingers. Yellowish cholesterol deposits under the skin of the eyelids are known as xanthelasmata. Cholesterol can also accumulate at the edges of the clear, front surface of the eye (the cornea), leading to a gray-colored ring called an arcus cornealis.
How many people are affected by hypercholesterolemia ? 
 More than 34 million American adults have elevated blood cholesterol levels (higher than 240 mg/dL). Inherited forms of hypercholesterolemia, which cause even higher levels of cholesterol, occur less frequently. The most common inherited form of high cholesterol is called familial hypercholesterolemia. This condition affects about 1 in 500 people in most countries. Familial hypercholesterolemia occurs more frequently in certain populations, including Afrikaners in South Africa, French Canadians, Lebanese, and Finns.
What are the genetic changes related to hypercholesterolemia ? 
 Mutations in the APOB, LDLR, LDLRAP1, and PCSK9 genes cause hypercholesterolemia.  High blood cholesterol levels typically result from a combination of genetic and environmental risk factors. Lifestyle choices including diet, exercise, and tobacco smoking strongly influence the amount of cholesterol in the blood. Additional factors that impact cholesterol levels include a person's gender, age, and health problems such as diabetes and obesity. A small percentage of all people with high cholesterol have an inherited form of hypercholesterolemia. The most common cause of inherited high cholesterol is a condition known as familial hypercholesterolemia, which results from mutations in the LDLR gene.  The LDLR gene provides instructions for making a protein called a low-density lipoprotein receptor. This type of receptor binds to particles called low-density lipoproteins (LDLs), which are the primary carriers of cholesterol in the blood. By removing low-density lipoproteins from the bloodstream, these receptors play a critical role in regulating cholesterol levels. Some LDLR mutations reduce the number of low-density lipoprotein receptors produced within cells. Other mutations disrupt the receptors' ability to remove low-density lipoproteins from the bloodstream. As a result, people with mutations in the LDLR gene have very high levels of blood cholesterol. As the excess cholesterol circulates through the bloodstream, it is deposited abnormally in tissues such as the skin, tendons, and arteries that supply blood to the heart.  Less commonly, hypercholesterolemia can be caused by mutations in the APOB, LDLRAP1, or PCSK9 gene. Changes in the APOB gene result in a form of inherited hypercholesterolemia known as familial defective apolipoprotein B-100 (FDB). LDLRAP1 mutations are responsible for another type of inherited high cholesterol, autosomal recessive hypercholesterolemia (ARH). Proteins produced from the APOB, LDLRAP1, and PCSK9 genes are essential for the normal function of low-density lipoprotein receptors. Mutations in any of these genes prevent the cell from making functional receptors or alter the receptors' function. Hypercholesterolemia results when low-density lipoprotein receptors are unable to remove cholesterol from the blood effectively.  Researchers are working to identify and characterize additional genes that may influence cholesterol levels and the risk of heart disease in people with hypercholesterolemia.
Is hypercholesterolemia inherited ? 
 Most cases of high cholesterol are not caused by a single inherited condition, but result from a combination of lifestyle choices and the effects of variations in many genes.  Inherited forms of hypercholesterolemia resulting from mutations in the LDLR, APOB, or PCSK9 gene have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means one copy of an altered gene in each cell is sufficient to cause the disorder. An affected person typically inherits one altered copy of the gene from an affected parent and one normal copy of the gene from the other parent.  Rarely, a person with familial hypercholesterolemia is born with two mutated copies of the LDLR gene. This situation occurs when the person has two affected parents, each of whom passes on one altered copy of the gene. The presence of two LDLR mutations results in a more severe form of hypercholesterolemia that usually appears in childhood.  When hypercholesterolemia is caused by mutations in the LDLRAP1 gene, the condition is inherited in an autosomal recessive pattern. Autosomal recessive inheritance means the condition results from two altered copies of the gene in each cell. The parents of an individual with autosomal recessive hypercholesterolemia each carry one copy of the altered gene, but their blood cholesterol levels are usually in the normal range.

What is (are) mucopolysaccharidosis type III ? 
 Mucopolysaccharidosis type III (MPS III), also known as Sanfilippo syndrome, is a progressive disorder that mainly affects the brain and spinal cord (central nervous system).  People with MPS III generally do not display any features of the condition at birth, but they begin to show signs and symptoms of the disorder during early childhood. Affected children often initially have delayed speech and behavior problems. They may become restless, destructive, anxious, or aggressive. Sleep disturbances are also very common in children with MPS III. This condition causes progressive intellectual disability and the loss of previously acquired skills (developmental regression). In later stages of the disorder, people with MPS III may develop seizures and movement disorders.  The physical features of MPS III are less pronounced than those of other types of mucopolysaccharidosis. Individuals with MPS III typically have mildly "coarse" facial features, a large head (macrocephaly), a slightly enlarged liver (mild hepatomegaly), and a soft out-pouching around the belly-button (umbilical hernia) or lower abdomen (inguinal hernia). Some people with MPS III have short stature, joint stiffness, or mild dysostosis multiplex, which refers to multiple skeletal abnormalities seen on x-ray. Affected individuals often develop chronic diarrhea and recurrent upper respiratory and ear infections. People with MPS III may also experience hearing loss and vision problems.  MPS III is divided into types IIIA, IIIB, IIIC, and IIID, which are distinguished by their genetic cause. The different types of MPS III have similar signs and symptoms, although the features of MPS IIIA typically appear earlier in life and progress more rapidly. People with MPS III usually live into adolescence or early adulthood.
How many people are affected by mucopolysaccharidosis type III ? 
 MPS III is the most common type of mucopolysaccharidosis; the estimated incidence of all four types combined is 1 in 70,000 newborns. MPS IIIA and MPS IIIB are much more common than MPS IIIC and MPS IIID.
What are the genetic changes related to mucopolysaccharidosis type III ? 
 Mutations in the GNS, HGSNAT, NAGLU, and SGSH genes cause MPS III. These genes provide instructions for making enzymes involved in the breakdown of large sugar molecules called glycosaminoglycans (GAGs). GAGs were originally called mucopolysaccharides, which is where this condition gets its name. The GNS, HGSNAT, NAGLU, and SGSH enzymes are involved in the step-wise breakdown of a subset of GAGs called heparan sulfate.  MPS IIIA is caused by mutations in the SGSH gene, and MPS IIIB is caused by NAGLU gene mutations. Mutations in the HGSNAT gene result in MPS IIIC, and GNS gene mutations cause MPS IIID. Mutations in these genes reduce or eliminate enzyme function. A lack of any one of these enzymes disrupts the breakdown of heparan sulfate. As a result, partially broken down heparan sulfate accumulates within cells, specifically inside the lysosomes. Lysosomes are compartments in the cell that digest and recycle different types of molecules. Conditions such as MPS III that cause molecules to build up inside the lysosomes are called lysosomal storage disorders. Researchers believe that the accumulation of GAGs interferes with the functions of other proteins inside the lysosomes and disrupts the normal functions of cells. It is unknown why the buildup of heparan sulfate mostly affects the central nervous system in MPS III.
Is mucopolysaccharidosis type III 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.

What is (are) GLUT1 deficiency syndrome ? 
 GLUT1 deficiency syndrome is a disorder affecting the nervous system that can have a variety of neurological signs and symptoms. Approximately 90 percent of affected individuals have a form of the disorder often referred to as common GLUT1 deficiency syndrome. These individuals generally have frequent seizures (epilepsy) beginning in the first months of life. In newborns, the first sign of the disorder may be involuntary eye movements that are rapid and irregular. Babies with common GLUT1 deficiency syndrome have a normal head size at birth, but growth of the brain and skull is often slow, which can result in an abnormally small head size (microcephaly). People with this form of GLUT1 deficiency syndrome may have developmental delay or intellectual disability. Most affected individuals also have other neurological problems, such as stiffness caused by abnormal tensing of the muscles (spasticity), difficulty in coordinating movements (ataxia), and speech difficulties (dysarthria). Some experience episodes of confusion, lack of energy (lethargy), headaches, or muscle twitches (myoclonus), particularly during periods without food (fasting).  About 10 percent of individuals with GLUT1 deficiency syndrome have a form of the disorder often known as non-epileptic GLUT1 deficiency syndrome, which is usually less severe than the common form. People with the non-epileptic form do not have seizures, but they may still have developmental delay and intellectual disability. Most have movement problems such as ataxia or involuntary tensing of various muscles (dystonia); the movement problems may be more pronounced than in the common form.  Several conditions that were originally given other names have since been recognized to be variants of GLUT1 deficiency syndrome. These include paroxysmal choreoathetosis with spasticity (dystonia 9); paroxysmal exercise-induced dyskinesia and epilepsy (dystonia 18); and certain types of epilepsy. In rare cases, people with variants of GLUT1 deficiency syndrome produce abnormal red blood cells and have uncommon forms of a blood condition known as anemia, which is characterized by a shortage of red blood cells.
How many people are affected by GLUT1 deficiency syndrome ? 
 GLUT1 deficiency syndrome is a rare disorder. Approximately 500 cases have been reported worldwide since the disorder was first identified in 1991. In Australia, the prevalence of the disorder has been estimated at 1 in 90,000 people. However, researchers suggest that the disorder may be underdiagnosed, because many neurological disorders can cause similar symptoms.
What are the genetic changes related to GLUT1 deficiency syndrome ? 
 GLUT1 deficiency syndrome is caused by mutations in the SLC2A1 gene. This gene provides instructions for producing a protein called the glucose transporter protein type 1 (GLUT1). The GLUT1 protein is embedded in the outer membrane surrounding cells, where it transports a simple sugar called glucose into cells from the blood or from other cells for use as fuel.  In the brain, the GLUT1 protein is involved in moving glucose, which is the brain's main energy source, across the blood-brain barrier. The blood-brain barrier acts as a boundary between tiny blood vessels (capillaries) and the surrounding brain tissue; it protects the brain's delicate nerve tissue by preventing many other types of molecules from entering the brain. The GLUT1 protein also moves glucose between cells in the brain called glia, which protect and maintain nerve cells (neurons).  SLC2A1 gene mutations reduce or eliminate the function of the GLUT1 protein. Having less functional GLUT1 protein reduces the amount of glucose available to brain cells, which affects brain development and function.
Is GLUT1 deficiency syndrome inherited ? 
 This condition is usually inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. About 90 percent of cases of GLUT1 deficiency syndrome result from new mutations in the gene. These cases occur in people with no history of the disorder in their family. In other cases, an affected person inherits the mutation from an affected parent.  In a small number of families, GLUT1 deficiency syndrome 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.
