Labcorp Genetics (formerly Invitae), Labcorp RCV001299258 SCV001488342 uncertain significance Cone-rod dystrophy 13; Leber congenital amaurosis 6 2022-10-04 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 sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. ClinVar contains an entry for this variant (Variation ID: 1002784). This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.004%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 878 of the RPGRIP1 protein (p.Glu878Lys).
