Summaries for GYG1 Gene

Entrez Gene Summary for GYG1 Gene

  • This gene encodes a member of the glycogenin family. Glycogenin is a glycosyltransferase that catalyzes the formation of a short glucose polymer from uridine diphosphate glucose in an autoglucosylation reaction. This reaction is followed by elongation and branching of the polymer, catalyzed by glycogen synthase and branching enzyme, to form glycogen. This gene is expressed in muscle and other tissues. Mutations in this gene result in glycogen storage disease XV. This gene has pseudogenes on chromosomes 1, 8 and 13 respectively. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Sep 2010]

GeneCards Summary for GYG1 Gene

GYG1 (Glycogenin 1) is a Protein Coding gene. Diseases associated with GYG1 include glycogen storage disease xv and polyglucosan body myopathy 2.

Disorders for GYG1 Gene

(1) OMIM Diseases for GYG1 Gene (603942)


  • Glycogen storage disease 15 (GSD15) [MIM:613507]: A metabolic disorder resulting in muscle weakness, associated with the glycogen depletion in skeletal muscle, and cardiac arrhythmia, associated with the accumulation of abnormal storage material in the heart. The skeletal muscle shows a marked predominance of slow-twitch, oxidative muscle fibers and mitochondrial proliferation. {ECO:0000269 PubMed:20357282}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Polyglucosan body myopathy 2 (PGBM2) [MIM:616199]: A glycogen storage disease characterized by polyglucosan accumulation in muscle, and skeletal myopathy without cardiac involvement. Most patients manifest slowly progressive, hip girdle, shoulder girdle, and/or hand and leg muscle weakness. Polyglucosan contains abnormally long and poorly branched glucosyl chains and is variably resistant to digestion by alpha-amylase. {ECO:0000269 PubMed:25272951}. Note=The disease is caused by mutations affecting the gene represented in this entry.
