Topic: cryptogenic cirrhosis
Question: What is (are) cryptogenic cirrhosis ?
Answer: Cryptogenic cirrhosis is a condition that impairs liver function. People with this condition develop irreversible liver disease caused by scarring of the liver (cirrhosis), typically in mid- to late adulthood.  The liver is a part of the digestive system that helps break down food, store energy, and remove waste products, including toxins. Minor damage to the liver can be repaired by the body. However, severe or long-term damage can lead to the replacement of normal liver tissue with scar tissue.  In the early stages of cryptogenic cirrhosis, people often have no symptoms because the liver has enough normal tissue to function. Signs and symptoms become apparent as more of the liver is replaced by scar tissue. Affected individuals can experience fatigue, weakness, loss of appetite, weight loss, nausea, swelling (edema), enlarged blood vessels, and yellowing of the skin and whites of the eyes (jaundice).  People with cryptogenic cirrhosis may develop high blood pressure in the vein that supplies blood to the liver (portal hypertension). Cryptogenic cirrhosis can lead to type 2 diabetes, although the mechanism is unclear. Some people with cryptogenic cirrhosis develop cancer of the liver (hepatocellular cancer).

Question: What are the genetic changes related to cryptogenic cirrhosis ?
Answer: Unlike most cases of cirrhosis, cryptogenic cirrhosis is not caused by the hepatitis C or B virus or chronic alcohol use. A diagnosis of cryptogenic cirrhosis is typically given when all other causes of cirrhosis have been ruled out. When a disorder occurs without an apparent underlying reason, it is described as cryptogenic.  Research has shown that many cases of cryptogenic cirrhosis likely result from a condition called non-alcoholic fatty liver disease (NAFLD). In NAFLD, fat accumulates in the liver, impairing its function. If the fat buildup leads to inflammation and damage to liver tissue, NAFLD progresses to a condition called non-alcoholic steatohepatitis (NASH). Long term inflammation in people with NASH can cause the formation of scar tissue and a decrease in fat buildup. As a result, individuals progress from NASH to cirrhosis.  Cryptogenic cirrhosis may also develop from autoimmune hepatitis, which is a condition that occurs when the body's immune system malfunctions and attacks the liver, causing inflammation and liver damage.  In very rare cases, cryptogenic cirrhosis has been associated with mutations in genes that provide instructions for making certain keratin proteins. Keratins are a group of tough, fibrous proteins that form the structural framework of certain cells, particularly cells that make up the skin, hair, nails, and similar tissues. People with these keratin gene mutations are more likely to have fibrous deposits in their livers than individuals without the mutations. These deposits impair liver function, leading to cirrhosis. Mutations in these genes have also been found in people with other liver disorders.  In many cases, the cause of cryptogenic cirrhosis is unknown. Many people with predisposing conditions do not develop cirrhosis. Researchers are working to discover the causes of cryptogenic cirrhosis as well as to find out why some people seem to be protected from developing cirrhosis and others seem to be susceptible.

Topic: cryptogenic cirrhosis
Question: Is cryptogenic cirrhosis inherited ?
Answer: Most cases of cryptogenic cirrhosis are not inherited. However, people with a family history of liver disease or autoimmune disease are at an increased risk of developing these diseases themselves, and possibly cirrhosis.  In individuals with an associated keratin gene mutation, the risk of developing cryptogenic cirrhosis appears to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means that one copy of an altered gene in each cell is sufficient to increase the risk of developing cryptogenic cirrhosis. In these families, people inherit an increased risk of cryptogenic cirrhosis, not the disease itself.

Topic: Glanzmann thrombasthenia
Question: What is (are) Glanzmann thrombasthenia ?
Answer: Glanzmann thrombasthenia is a bleeding disorder that is characterized by prolonged or spontaneous bleeding starting from birth. People with Glanzmann thrombasthenia tend to bruise easily, have frequent nosebleeds (epistaxis), and may bleed from the gums. They may also develop red or purple spots on the skin caused by bleeding underneath the skin (petechiae) or swelling caused by bleeding within tissues (hematoma). Glanzmann thrombasthenia can also cause prolonged bleeding following injury, trauma, or surgery (including dental work). Women with this condition can have prolonged and sometimes abnormally heavy menstrual bleeding. Affected women also have an increased risk of excessive blood loss during pregnancy and childbirth.  About a quarter of individuals with Glanzmann thrombasthenia have bleeding in the gastrointestinal tract, which often occurs later in life. Rarely, affected individuals have bleeding inside the skull (intracranial hemorrhage) or joints (hemarthrosis).  The severity and frequency of the bleeding episodes in Glanzmann thrombasthenia can vary greatly among affected individuals, even in the same family. Spontaneous bleeding tends to become less frequent with age.

Topic: Glanzmann thrombasthenia
Question: What are the genetic changes related to Glanzmann thrombasthenia ?
Answer: Mutations in the ITGA2B or ITGB3 gene cause Glanzmann thrombasthenia. These genes provide instructions for making the two parts (subunits) of a receptor protein called integrin alphaIIb/beta3 (IIb3). This protein is abundant on the surface of platelets. Platelets are small cell fragments that circulate in blood and are an essential component of blood clots. During clot formation, integrin IIb3 helps platelets bind together. Blood clots protect the body after injury by sealing off damaged blood vessels and preventing further blood loss.  ITGA2B or ITGB3 gene mutations result in a shortage (deficiency) of functional integrin IIb3. As a result, platelets cannot clump together to form a blood clot, leading to prolonged bleeding.  Three types of Glanzmann thrombasthenia have been classified according to the amount of integrin IIb3 that is available. People with type I (the most common type) have less than 5 percent of normal integrin IIb3 levels, people with type II have between 5 and 20 percent of normal integrin IIb3 levels, and people with the variant type have adequate integrin IIb3 levels but produce only nonfunctional integrin.  Some people with Glanzmann thrombasthenia do not have an identified mutation in either the ITGA2B or ITGB3 gene; the cause of the disorder in these individuals is unknown.

Topic: galactosialidosis
Question: What is (are) galactosialidosis ?
Answer: Galactosialidosis is a condition that affects many areas of the body. The three forms of galactosialidosis are distinguished by the age at which symptoms develop and the pattern of features.  The early infantile form of galactosialidosis is associated with extensive swelling caused by fluid accumulation before birth (hydrops fetalis), a soft out-pouching in the lower abdomen (an inguinal hernia), and an enlarged liver and spleen (hepatosplenomegaly). Additional features of this form include abnormal bone development (dysostosis multiplex) and distinctive facial features that are often described as "coarse." Some infants have an enlarged heart (cardiomegaly); an eye abnormality called a cherry-red spot, which can be identified with an eye examination; and kidney disease that can progress to kidney failure. Infants with this form usually are diagnosed between birth and 3 months; they typically live into late infancy.  The late infantile form of galactosialidosis shares some features with the early infantile form, although the signs and symptoms are somewhat less severe and begin later in infancy. This form is characterized by short stature, dysostosis multiplex, heart valve problems, hepatosplenomegaly, and "coarse" facial features. Other symptoms seen in some individuals with this type include intellectual disability, hearing loss, and a cherry-red spot. Children with this condition typically develop symptoms within the first year of life. The life expectancy of individuals with this type varies depending on the severity of symptoms.  The juvenile/adult form of galactosialidosis has signs and symptoms that are somewhat different than those of the other two types. This form is distinguished by difficulty coordinating movements (ataxia), muscle twitches (myoclonus), seizures, and progressive intellectual disability. People with this form typically also have dark red spots on the skin (angiokeratomas), abnormalities in the bones of the spine, "coarse" facial features, a cherry-red spot, vision loss, and hearing loss. The age at which symptoms begin to develop varies widely among affected individuals, but the average age is 16. This form is typically associated with a normal life expectancy.

Topic: galactosialidosis
Question: What are the genetic changes related to galactosialidosis ?
Answer: Mutations in the CTSA gene cause all forms of galactosialidosis. The CTSA gene provides instructions for making a protein called cathepsin A, which is active in cellular compartments called lysosomes. These compartments contain enzymes that digest and recycle materials when they are no longer needed. Cathepsin A works together with two enzymes, neuraminidase 1 and beta-galactosidase, to form a protein complex. This complex breaks down sugar molecules (oligosaccharides) attached to certain proteins (glycoproteins) or fats (glycolipids). Cathepsin A is also found on the cell surface, where it forms a complex with neuraminidase 1 and a protein called elastin binding protein. Elastin binding protein plays a role in the formation of elastic fibers, a component of the connective tissues that form the body's supportive framework.  CTSA mutations interfere with the normal function of cathepsin A. Most mutations disrupt the protein structure of cathepsin A, impairing its ability to form complexes with neuraminidase 1, beta-galactosidase, and elastin binding protein. As a result, these other enzymes are not functional, or they break down prematurely.  Galactosialidosis belongs to a large family of lysosomal storage disorders, each caused by the deficiency of a specific lysosomal enzyme or protein. In galactosialidosis, impaired functioning of cathepsin A and other enzymes causes certain substances to accumulate in the lysosomes.

Topic: glycogen storage disease type VII
Question: What is (are) glycogen storage disease type VII ?
Answer: Glycogen storage disease type VII (GSDVII) is an inherited disorder caused by an inability to break down a complex sugar called glycogen in muscle cells. A lack of glycogen breakdown interferes with the function of muscle cells.  There are four types of GSDVII. They are differentiated by their signs and symptoms and the age at which symptoms first appear.  The classical form of GSDVII is the most common form. Its features usually appear in childhood. This form is characterized by muscle pain and cramps, often following moderate exercise; strenuous exercise can lead to nausea and vomiting. During exercise, muscle tissue can be abnormally broken down, releasing a protein called myoglobin. This protein is processed by the kidneys and released in the urine (myoglobinuria). If untreated, myoglobinuria can damage the kidneys and lead to kidney failure. Some people with the classical form of GSDVII develop high levels of a waste product called uric acid in the blood (hyperuricemia) because the damaged kidneys are unable to remove uric acid effectively. Affected individuals may also have elevated levels of a molecule called bilirubin in the blood that can cause yellowing of the skin and whites of the eyes (jaundice). Individuals with classical GSDVII often have elevated levels of an enzyme called creatine kinase in their blood. This finding is a common indicator of muscle disease.  Infants with the severe infantile form of GSDVII have low muscle tone (hypotonia) at birth, which leads to muscle weakness (myopathy) that worsens over time. Affected infants have a weakened and enlarged heart (cardiomyopathy) and difficulty breathing normally. Individuals with this form of GSDVII usually do not survive past their first year of life.  In the late-onset form of GSDVII, myopathy is typically the only feature. The muscle weakness appears in adulthood, although some individuals have difficulty with sustained exercise starting in childhood. The weakness generally affects the muscles closest to the center of the body (proximal muscles).  The hemolytic form of GSDVII is characterized by hemolytic anemia, in which red blood cells are broken down (undergo hemolysis) prematurely, causing a shortage of red blood cells (anemia). People with the hemolytic form of GSDVII do not experience any signs or symptoms of muscle pain or weakness related to the disorder.

Topic: glycogen storage disease type VII
Question: What are the genetic changes related to glycogen storage disease type VII ?
Answer: Mutations in the PFKM gene cause GSDVII. This gene provides instructions for making one piece (the PFKM subunit) of an enzyme called phosphofructokinase, which plays a role in the breakdown of glycogen. The phosphofructokinase enzyme is made up of four subunits and is found in a variety of tissues. Different combinations of subunits are found in different tissues. In muscles used for movement (skeletal muscles), the phosphofructokinase enzyme is composed solely of PFKM subunits.  In skeletal muscle, the cells' main source of energy is stored as glycogen. Glycogen can be broken down rapidly into the simple sugar glucose when energy is needed, for instance to maintain normal blood sugar levels between meals or for energy during exercise. Phosphofructokinase is involved in the sequence of events that breaks down glycogen to provide energy to muscle cells.  PFKM gene mutations result in the production of PFKM subunits that have little or no function. As a result, no functional phosphofructokinase is formed in skeletal muscles, and glycogen cannot be completely broken down. Partially broken down glycogen then builds up in muscle cells. Muscles that do not have access to glycogen as an energy source become weakened and cramped following moderate strain, such as exercise, and in some cases, begin to break down. In other tissues, other subunits that make up the phosphofructokinase enzyme likely compensate for the lack of PFKM subunits, and the enzyme is able to retain some function. This compensation may help explain why other tissues are not affected by PFKM gene mutations. It is unclear why some individuals with GSDVII are affected with more severe forms of the disorder than others.

Topic: tyrosine hydroxylase deficiency
Question: What is (are) tyrosine hydroxylase deficiency ?
Answer: Tyrosine hydroxylase (TH) deficiency is a disorder that primarily affects movement, with symptoms that may range from mild to severe.  The mild form of this disorder is called TH-deficient dopa-responsive dystonia (DRD). Symptoms usually appear during childhood. Affected individuals may exhibit unusual limb positioning and a lack of coordination when walking or running. In some cases, people with TH-deficient DRD have additional movement problems such as shaking when holding a position (postural tremor) or involuntary upward-rolling movements of the eyes. The movement difficulties may slowly increase with age but almost always get better with medical treatment.  The severe forms of TH deficiency are called infantile parkinsonism and progressive infantile encephalopathy. These forms of the disorder appear soon after birth and are more difficult to treat effectively.  Babies with infantile parkinsonism have delayed development of motor skills such as sitting unsupported or reaching for a toy. They may have stiff muscles, especially in the arms and legs; unusual body positioning; droopy eyelids (ptosis); and involuntary upward-rolling eye movements. The autonomic nervous system, which controls involuntary body functions, may also be affected. Resulting signs and symptoms can include constipation, backflow of stomach acids into the esophagus (gastroesophageal reflux), and difficulty regulating blood sugar, body temperature, and blood pressure. People with the infantile parkinsonism form of the disorder may have intellectual disability, speech problems, attention deficit disorder, and psychiatric conditions such as depression, anxiety, or obsessive-compulsive behaviors.  Progressive infantile encephalopathy is an uncommon severe form of TH deficiency. It is characterized by brain dysfunction and structural abnormalities leading to profound physical and intellectual disability.

Topic: tyrosine hydroxylase deficiency
Question: What are the genetic changes related to tyrosine hydroxylase deficiency ?
Answer: Mutations in the TH gene cause TH deficiency. The TH gene provides instructions for making the enzyme tyrosine hydroxylase, which is important for normal functioning of the nervous system. Tyrosine hydroxylase takes part in the pathway that produces a group of chemical messengers (hormones) called catecholamines. Tyrosine hydroxylase helps convert the protein building block (amino acid) tyrosine to a catecholamine called dopamine. Dopamine transmits signals to help the brain control physical movement and emotional behavior. Other catecholamines called norepinephrine and epinephrine are produced from dopamine. Norepinephrine and epinephrine are involved in the autonomic nervous system.  Mutations in the TH gene result in reduced activity of the tyrosine hydroxylase enzyme. As a result, the body produces less dopamine, norepinephrine and epinephrine. These catecholamines are necessary for normal nervous system function, and changes in their levels contribute to the abnormal movements, autonomic dysfunction, and other neurological problems seen in people with TH deficiency.
