FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of several forms of glutamic acid decarboxylase, identified as a major autoantigen in insulin-dependent diabetes. The enzyme encoded is responsible for catalyzing the production of gamma-aminobutyric acid from L-glutamic acid. A pathogenic role for this enzyme has been identified in the human pancreas since it has been identified as an autoantibody and an autoreactive T cell target in insulin-dependent diabetes. This gene may also play a role in the stiff man syndrome. Alternative splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Oct 2008]
PHENOTYPE: Homozygotes for targeted null mutations exhibit spontaneous (frequently fatal) seizures, increased anxiety-like behavior, and reduced intermale aggression. Heterozygotes show reduced aggressiveness. [provided by MGI curators]
