GeneDx RCV000085471 SCV000511885 likely pathogenic not provided 2016-02-01 criteria provided, single submitter clinical testing The V767D variant has been reported in association with ABCA4-related disorders (Bertelsen et al., 2014; Klevering et al., 2004; Stenirri et al., 2004; Duno et al., 2012; Zernant et al., 2011). In vitro functional studies demonstrated that the presence of the V767D variant results in severely reduce ABCR protein expression (Shroyer et al., 2001). The V767D variant 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 V767D 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. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. This variant is likely pathogenic; however, the possibility that it is benign cannot be excluded.
