GeneDx RCV000188278 SCV000241889 uncertain significance not provided 2016-05-27 criteria provided, single submitter clinical testing The R896W variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. It was not observed in approximately 6,100 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 R896W variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other 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, other missense mutations in nearby residues have not been reported in the Human Gene Mutation Database (Stenson et al., 2014). Based on the currently available information, it is unclear whether the R896W variant is a pathogenic mutation or a rare benign variant.
