FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene, liver glycogen synthase, catalyzes the rate-limiting step in the synthesis of glycogen - the transfer of a glucose molecule from UDP-glucose to a terminal branch of the glycogen molecule. Mutations in this gene cause glycogen storage disease type 0 (GSD-0) - a rare type of early childhood fasting hypoglycemia with decreased liver glycogen content. [provided by RefSeq, Dec 2009]
PHENOTYPE: Mice homozygous for a conditional allele knocked out in the liver results in abnormal glycogen homeostasis, altered glucose homeostasis, decreased exercise endurance, and a phenotype similar to patients with glycogen storage disease 0. [provided by MGI curators]
