GABRB3 - gamma-aminobutyric acid type A receptor subunit beta3 Gene
Also Known as ECA5; DEE43; EIEE43
Species: Homo sapiens
About GABRB3
This gene has 26 transcripts (splice variants), 213 orthologues, 45 paralogues and is associated with 6 phenotypes. Biased expression in brain (RPKM 22.9), gall bladder (RPKM 6.3) and 7 other tissues.
Summary
This gene encodes a member of the ligand-gated ionic channel family. The encoded protein is one the subunits of a multi-subunit Chloride Channel that serves as the receptor for gamma-aminobutyric acid, a major inhibitory neurotransmitter of the mammalian nervous system. This gene is located on the long arm of chromosome 15 in a cluster with two Other genes encoding related subunits of the family. This gene may be associated with the pathogenesis of several disorders including Angelman syndrome, Prader-Willi syndrome, nonsyndromic orofacial clefts, epilepsy and autism. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2013]
