Gene Gene information from NCBI Gene database.
Entrez ID 2550
Gene name Gamma-aminobutyric acid type B receptor subunit 1
Gene symbol GABBR1
Synonyms (NCBI Gene)
GABABR1GABBR1-3GB1GPRC3ANEDLC
Chromosome 6
Chromosome location 6p22.1
Summary This gene encodes a receptor for gamma-aminobutyric acid (GABA), which is the main inhibitory neurotransmitter in the mammalian central nervous system. This receptor functions as a heterodimer with GABA(B) receptor 2. Defects in this gene may underlie bra
