MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a knock-out allele are viable and fertile with normal cerebellar cytoarchitecture and normal responses to ethanol, pentobarbital and general anesthetics. Mice homozygous for a reporter allele are behaviorally normal and lack a cochlear phenotype. [provided by MGI curators]
