Glycogen Synthase 1; Glycogen Synthase 1 (Muscle); EC 2.4.1.11; GYS; Glycogen [Starch] Synthase, Muscle; GSY

The protein encoded by this gene catalyzes the addition of glucose monomers to the growing glycogen molecule through the formation of alpha-1,4-glycoside linkages. Mutations in this gene are associated with muscle glycogen storage disease. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
