GeneDx RCV000085804 SCV000616627 pathogenic not provided 2017-10-24 criteria provided, single submitter clinical testing The E2096K variant in the ABCA4 gene has been published previously in association with Stargardt disease (Lewis et al., 1999; Shroyer et al., 2001; Utz et al., 2013). The variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). E2096K 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. Additionally, E2096K has been shown to significantly reduce ATPase activity of the ABCA4 protein (Sun et al., 2000). In summary, we consider this variant to be pathogenic
