Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Arg347 amino acid residue in RPE65. Other variant(s) that disrupt this residue have been observed in individuals with RPE65-related conditions (PMID: 29178642, 31630094), which suggests that this may be a clinically significant amino acid residue. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with RPE65-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 347 of the RPE65 protein (p.Arg347Leu).
