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 1 subunit. It is mapped to chromosome 4p12 in a cluster comprised of genes encoding alpha 4, alpha 2 and gamma 1 subunits of the GABA A receptor. Alteration of this gene is implicated in the pathogenetics of schizophrenia. [provided by RefSeq, Jul 2008]

A study in mice selectively bred for high or low methamphetamine intake identified the GABRB1 as a differentially wired gene in the prefrontal cortex, indicating its transcriptomic association with innate risk for addiction in this brain region [Hitzemann et al. DOI:10.3390/brainsci9070155].
