Gene:
gamma-aminobutyric acid (GABA) receptor, theta
Description:
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, theta subunit. It is mapped to chromosome Xq28 in a cluster including the genes encoding the alpha 3 and epsilon subunits of the same receptor. This gene location is also the candidate region of 2 different neurologic diseases: early-onset parkinsonism (Waisman syndrome) and X-linked mental retardation (MRX3).
