Labcorp Genetics (formerly Invitae), Labcorp RCV001057785 SCV001222297 uncertain significance Cone-rod dystrophy 13; Leber congenital amaurosis 6 2022-07-18 criteria provided, single submitter clinical testing 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. This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 977 of the RPGRIP1 protein (p.Ala977Val). This variant is not present in population databases (gnomAD no frequency). ClinVar contains an entry for this variant (Variation ID: 853047). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function.
