Labcorp Genetics (formerly Invitae), Labcorp RCV002640581 SCV003519995 uncertain significance Leber congenital amaurosis 2; Retinitis pigmentosa 20 2022-03-10 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 453 of the RPE65 protein (p.Lys453Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RPE65-related conditions. 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 tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
