GeneDx RCV000437482 SCV000519001 uncertain significance not provided 2016-06-20 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the ARFGEF2 gene. The R926Q variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The R926Q 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, and in silico analysis predicts this variant is probably damaging to the protein structure/function. However, missense variants in nearby residues have not been reported in Human Gene Mutation Database (Stenson et al., 2014). Based on the currently available information, it is unclear whether the R926Q variant is a pathogenic variant or a rare benign variant.
