| glycogen storage disease type VI | <disease> A hepatic glycogen storage disease in which there is an apparent deficiency of hepatic phosphorylase activity. However, studies have not been able to distinguish between phosphorylase deficiency and phosphorylase kinase deficiency in patients with hepatic glycogenosis. (12 Dec 1998) |
|---|---|
| glycogen storage disease type VII | <disease> An autosomal recessive muscle glycogen storage disease in which there is deficient expression of muscle phosphofructokinase activity, resulting in increased concentrations of glucose-6-phosphate and fructose-6-phosphate and low concentrations of fructose-1,6-diphosphate in muscle tissue. Glycogen storage in muscle is increased, perhaps due to activation of glycogen synthase by accumulated glucose-6-phosphate. It has been proposed that shunting of glucose-6-phosphate and fructose-6-phosphate into the pentose phosphate pathway may result in increased synthesis of purines and pyrimidines, causing hyperuricaemia and gout. Erythrocytes from patients may show decreased phosphofructokinase activity and 2,3-diphosphoglycerate deficiency. Exercise intolerance is present and severe congenital muscular dystrophy has been reported. Inheritance: autosomal recessive (12 Dec 1998) |
| glycogen storage disease type VIII | <disease> An x-linked recessive hepatic glycogen storage disease resulting from lack of expression of phosphorylase-b-kinase activity. Symptoms are relatively mild; hepatomegaly, increased liver glycogen, and decreased leukocyte phosphorylase are present. Liver shrinkage occurs in response to glucagon. Inheritance: X-linked recessive (12 Dec 1998) |
| glycogen synthase | <enzyme> An enzyme of the transferase class that catalyses the reaction of udpglucose and (1,4-alpha-d-glucosyl)n to yield udp and 1,4-alpha-d-glucosyl)n+1. The reaction is highly regulated by allosteric effectors, by phosphorylation reactions, and by insulin. Chemical name: UDPglucose:glycogen 4-alpha-D-glucosyltransferase Registry number: EC 2.4.1.11 (12 Dec 1998) |
| glycogen synthase-d phosphatase | <enzyme> An enzyme that catalyses the conversion of phosphorylated, inactive glycogen synthase d to active dephosphoglycogen synthase I. Chemical name: (UDPglucose:glycogen 4-alpha-D-glucosyltransferase-D) phosphohydrolase Registry number: EC 3.1.3.42 (12 Dec 1998) |
| glycogen synthetase | <enzyme> An enzyme which makes amylose out of glucose molecules (a type of sugar) and attaches them to glycogen (a type of polysaccharide). (09 Oct 1997) |
| glycogenase | alpha-amylase, beta-amylase |
| glycogenesis | The formation of glycogen from food. (27 Sep 1997) |
| glycogenetic | Glycogenic;relating to glycogenesis. Synonym: d-glycogenous. (05 Mar 2000) |
| glycogenic | Giving rise to or producing glycogen. (05 Mar 2000) |
| glycogenic acanthosis | <radiology> Benign, multiple small mucosal nodules in oesophagus, degenerative accumulation of glycogen in squamous epithelium (12 Dec 1998) |
| glycogenolysis | The breaking down, or catabolism, of the polysaccharide glycogen into molecules of the sugar glucose and molecules of glucose 1-phosphate within the body by enzymes. The enzymes are controlled by nerve impulses and hormones. Origin: Gr. Lysis = dissolution (09 Oct 1997) |
| glycogenosis | Any of the glycogen deposition diseases characterised by accumulation of glycogen of normal or abnormal chemical structure in tissue; there may be enlargement of the liver, heart, or striated muscle, including the tongue, with progressive muscular weakness. Seven types (Cori classification) are recognised, depending on the enzyme deficiency involved, all of autosomal recessive inheritance, but with a different gene for each enzyme deficiency. Synonym: dextrinosis, glycogen-storage disease. (05 Mar 2000) |
| glycogeusia | A subjective sweet taste. Origin: Glyco-+ G. Geusis, taste (05 Mar 2000) |
| glycoglycinuria | A metabolic disorder characterised by glucosuria and hyperglycinuria; autosomal dominant inheritance. (05 Mar 2000) |
