Genes affected

GABRA6 (HGNC:4080): (gamma-aminobutyric acid type A receptor subunit alpha6) GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified.

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.12).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.562 is higher than 0.05.
