MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The gamma-aminobutyric acid (GABA) A receptor is a multisubunit chloride channel that mediates the fastest inhibitory synaptic transmission in the central nervous system. This gene encodes GABA A receptor, beta 2 subunit. It is mapped to chromosome 5q34 in a cluster comprised of genes encoding alpha 1 and gamma 2 subunits of the GABA A receptor. Alternative splicing of this gene generates 2 transcript variants, differing by a 114 bp insertion. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a null allele show hyperactivity and abnormal GABA-mediated receptor currents. Homozygotes for a derivative of this allele show a sexually dimorphic cochlear phenotype associated with OHC dysfunction. Homozygotes for a knock-in allele show altered behavioral response to etomidate. [provided by MGI curators]
