MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a mitochondrial enzyme that belongs to the amidinotransferase family. This enzyme is involved in creatine biosynthesis, whereby it catalyzes the transfer of a guanido group from L-arginine to glycine, resulting in guanidinoacetic acid, the immediate precursor of creatine. Mutations in this gene cause arginine:glycine amidinotransferase deficiency, an inborn error of creatine synthesis characterized by mental retardation, language impairment, and behavioral disorders.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit resistance obesity, reduced adipocity and improved glucose homeostasis when fed a high fat diet. Mice homozygous for an ENU-induced allele exhibit increased susceptibility to DSS-induced colitis. [provided by MGI curators]
