Labcorp Genetics (formerly Invitae), Labcorp RCV001872572 SCV002125285 uncertain significance Cone-rod dystrophy 13; Leber congenital amaurosis 6 2023-12-22 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with lysine, which is basic and polar, at codon 483 of the RPGRIP1 protein (p.Gln483Lys). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1360735). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt RPGRIP1 protein function with a positive predictive value of 80%. 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.
