Labcorp Genetics (formerly Invitae), Labcorp RCV001903356 SCV002160056 uncertain significance Cone-rod dystrophy 13; Leber congenital amaurosis 6 2021-01-29 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. 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with RPGRIP1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with glycine at codon 223 of the RPGRIP1 protein (p.Ser223Gly). The serine residue is weakly conserved and there is a small physicochemical difference between serine and glycine.
