Summaries for AGL Gene

Entrez Gene Summary for AGL Gene

  • This gene encodes the glycogen debrancher enzyme which is involved in glycogen degradation. This enzyme has two independent catalytic activities which occur at different sites on the protein: a 4-alpha-glucotransferase activity and a amylo-1,6-glucosidase activity. Mutations in this gene are associated with glycogen storage disease although a wide range of enzymatic and clinical variability occurs which may be due to tissue-specific alternative splicing. Alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for AGL Gene

AGL (Amylo-Alpha-1, 6-Glucosidase, 4-Alpha-Glucanotransferase) is a Protein Coding gene. Diseases associated with AGL include Glycogen Storage Disease Iii and Glycogen Storage Disease Iv.

Tocris Summary for AGL Gene

  • Glycosylases are a group of enzymes that includes glucosidases, mannosidases and heparanases. There are two glucosidase subtypes, both found in the gut. They hydrolyze terminal (1,4)alpha-glucosidic linkages and (1,6)beta-glucosidic linkages, liberating alpha-glucose and beta-glucose.

  • Glycogen storage disease 3 (GSD3) [MIM:232400]: A metabolic disorder associated with an accumulation of abnormal glycogen with short outer chains. It is clinically characterized by hepatomegaly, hypoglycemia, short stature, and variable myopathy. Glycogen storage disease type 3 includes different forms: GSD type 3A patients lack glycogen debrancher enzyme activity in both liver and muscle, while GSD type 3B patients are enzyme-deficient in liver only. In rare cases, selective loss of only 1 of the 2 debranching activities, glucosidase or transferase, results in GSD type 3C or type 3D, respectively. {ECO:0000269 PubMed:10571954, ECO:0000269 PubMed:17908927}. Note=The disease is caused by mutations affecting the gene represented in this entry.
