Genes affected

GABRR3 (HGNC:17969): (gamma-aminobutyric acid type A receptor subunit rho3) The neurotransmitter gamma-aminobutyric acid (GABA) functions in the central nervous system to regulate synaptic transmission of neurons. This gene encodes one of three related subunits, which combine as homo- or hetero-pentamers to form GABA(C) receptors. In humans, some individuals contain a single-base polymorphism (dbSNP rs832032) that is predicted to inactivate the gene product. [provided by RefSeq, Jan 2012]

The c.736G>T (p.A246S) alteration is located in exon 7 (coding exon 6) of the GABRR3 gene. This alteration results from a G to T substitution at nucleotide position 736, causing the alanine (A) at amino acid position 246 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
