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 -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00162 (247/152092) while in subpopulation EAS AF = 0.0449 (233/5184). AF 95% confidence interval is 0.0402. There are 6 homozygotes in GnomAd4. There are 151 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene
