Glycogen Metabolism In addition, although the glycogen storage diseases are attributed to specific enzyme deficiencies, other events can cause the same characteristic symptoms. For example, Type I glycogen storage disease (von Gierke disease) is attributed to lack of glucose-6-phosphatase.lycogen is a polymer of glucose residues linked by α-(1,4)- and α-(1,6)-glycosidic bonds. A second major source of stored glucose is the glycogen of skeletal muscle. However, muscle glycogen is not generally available to other tissues, because muscle lacks the enzyme glucose-6-phosphatase.

- Background. A glycogen storage disease (GSD) results from the absence of enzymes that ultimately convert glycogen compounds to glucose. Enzyme deficiency results in glycogen accumulation in tissues. In many cases, the defect has systemic consequences, but, in some cases, the defect is limited to specific tissues.onversion generally is a one-way reaction from glycogen to glucose-1,6-phosphate. The enzyme is found in all tissues. Disease results from a pan-deficiency of the enzyme (GSD IIIa) or muscle-specific retention of glycogen debranching enzyme (GSD IIIb). The condition is autosomal recessive.

- Alkaptonuria (AKU) is an inborn error of metabolism: a genetic disease caused by a lack of the enzyme homogentisate dioxygenase (HGD). Without HGD, patients cannot break down protein to amino acids, such as tyrosine and phenylalanine, which causes a build up of homogentisic acid (HGA) in the bones, cartilage and urine.

Lactate dehydrogenase deficiency Lactate dehydrogenase deficiency is a condition that affects how the body breaks down sugar to use as energy in cells, primarily muscle cells. There are two types of this condition: lactate dehydrogenase-A deficiency (sometimes called glycogen storage disease XI) and lactate dehydrogenase-B deficiency.People with lactate dehydrogenase-A deficiency experience fatigue, muscle pain, and cramps during exercise (exercise intolerance).ven though lactate dehydrogenase activity is decreased in the cardiac muscle of people with lactate dehydrogenase-B deficiency, they do not appear to have any signs or symptoms related to their condition. It is unclear why this type of enzyme deficiency does not cause any health problems.

Tay-Sachs Disease What is Tay-Sachs disease? Tay-Sachs disease (the most severe form of Hexosaminidase A deficiency) is a progressive, fatal genetic condition that affects the nerve cells in the brain. People with Tay-Sachs lack a specific protein (enzyme) called hexosaminidase A.

- 3.Fatal infantile multisystem disorder – characterized by poor muscle tone, developmental delay, heart disease, lactic acidosis, and respiratory failure. Most cases of Complex I deficiency result from autosomal recessive inheritance (combination of defective nuclear genes from both the mother and the father). Less frequently, the disorder is maternally inherited or sporadic and the genetic defect is in the mitochondrial DNA.

Ornithine transcarbamylase deficiency Ornithine transcarbamylase 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.

- It is the inability of the body to completely process carbohydrates (sugars and starches) due to lack or inadequate amount of one or more of the enzymes needed for their digestion. Lactose Intolerance is the most common one but the inability to break down starch is also common.

Tay-sachs Disease Children with Tay-Sachs disease lack a vital enzyme, hexosaminidase A (Hex-A). Hex-A is needed for the body to break down a fatty waste substance found in brain cells. Without Hex-A, this substance accumulates abnormally and causes progressive damage until the nervous system can no longer sustain life.

Diseases Caused by Lack of Vitamins Scurvy. Scurvy is a disorder of vitamin deficiency arising from a lack of vitamin C, also known as ascorbic acid. Vitamin C is essential for immune function, wound healing and collagen production. Collagen is a necessary component of connective tissue in your bones, cartilage, skin and ligaments.

Biology Exams 4 U Lack of the enzyme phenylalanine hydroxylase is due to the the abnormal autosomal recessive gene on chromosome 12. In children, symptoms are mental retardation, decrease pigmentation of hair and skin and eczema. The heterozygous individuals are normal but carriers. It occurs in about 1 in 18000 births among Europeans. Albinism. Albinism is characterized by the lack of dark pigment melanin in the skin, hair and iris. Caused by the absence of thyrosinase which is necessary for the synthesis of the pigment melanin from dihydroxyphenylalanine. The gene for albinism (a) does not produce the enzyme tyrosinase, but its normal allele (A) does.Thus, only homozygous individuals (aa) is affected.

- Fabry disease is a rare, inherited disease caused by the deficiency of an enzyme called alpha galactosidase A (a-GAL A), which is encoded by the GLA gene.In patients with Fabry disease, a-GAL A is either lacking or deficient. They should be taken daily. 2  Enzyme replacement therapy (ERT) - ERT is a medical treatment that replaces an enzyme which is either absent or deficient in patients. 3  In Fabry disease patients' cases, the missing enzyme is alpha galactosidase A (a-GAL A).

What is congenital adrenal hyperplasia? In close to 95 percent of cases, the missing enzyme is called 21-hydroxylase. CAH caused by this missing enzyme is called 21-hydroxylase deficiency. There are two forms of congenital adrenal hyperplasia caused by 21-hydroxylase deficiency. Classical CAH: This is the most severe form of the disease and is less common.

NIH team discovers genetic disorder causing strokes and vascular inflammation in children The researchers showed that faulty variants in their patients' DNA that encode the CECR1 gene cause a loss of function of the gene's ability to produce of an enzyme called adenosine deaminase 2 (ADA2). Without it, abnormalities and inflammation in blood vessel walls result.

- What’s Missing Historically, lysosomal storage disorders have been described as a group of disorders caused by missing enzymes. This description suggests that enzyme is missing from the body completely. While some individuals with lysosomal storage disorders do not make any enzyme, many individuals do make enzyme.

- Galactosemia is a rare hereditary disease that can lead to cirrhosis in infants, and early, devastating illness if not diagnosed quickly. This disease is caused by elevated levels of galactose (a sugar in milk) in the blood resulting from a deficiency of the liver enzyme required for its metabolism (breakdown).

A to Z List of Neurological Disorders Each of the leukodystrophies affects one (and only one) of these substances. Krabbe disease is caused by a deficiency of galactocerebrosidase, an essential enzyme for myelin metabolism.The disease most often affects infants, with onset before age 6 months, but can occur in adolescence or adulthood.t is characterized by the presence of globoid cells (cells that have more than one nucleus), the breakdown of the nerve’s protective myelin coating, and destruction of brain cells. Krabbe disease is one of a group of genetic disorders called the leukodystrophies.

- In Hurler syndrome, the body has a defective gene and cannot make an important enzyme. Enzymes are proteins inside cells that break down larger building block chemicals into smaller ones. When the body is missing a certain type of enzyme, the cells can't work properly.

A to Z List of Neurological Disorders Acid lipase disease or deficiency occurs when the enzyme needed to break down certain fats that are normally digested by the body is lacking or missing, resulting in the toxic buildup of these fats in the body’s cells and tissues. These fatty substances, called lipids, include fatty acids, oils, and cholesterol.olman’s disease (also known as acid lipase deficiency) is an autosomal recessive disorder marked by the buildup of cholesteryl esters (normally a tranport form of cholesterol that brings nutrients into the cells and carries out waste) and triglycerides (a chemical form in which fats exist in the body).
