GeneDx RCV000484482 SCV000565062 uncertain significance not provided 2017-02-27 criteria provided, single submitter clinical testing The R302S variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R302S variant is observed in 0.1%-1% alleles from individuals of African background, in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R302S 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 not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. In summary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.

Ambry Genetics RCV002525761 SCV003748929 likely benign Inborn genetic diseases 2022-01-07 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
