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.

PHENOTYPE: Hemizygous males exhibit hyperactivity and an increased startle response with impaired prepulse inhibition. [provided by MGI curators]
