GeneDx RCV000187531 SCV000241125 pathogenic not provided 2016-12-01 criteria provided, single submitter clinical testing A R323Q variant that is pathogenic has been identified in the GABRG2 gene. The R323Q variant has been reported multiple times in association with epilepsy (Carvill et. al., 2013; Reinthaler et. al., 2015). Functional studies demonstrate that the R323Q variant impairs protein function (Reinthaler et. al., 2015). The R323Q variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R323Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species. Therefore, the presence of R323Q is consistent with a diagnosis of a GABRG2-related disorder
