Labcorp Genetics (formerly Invitae), Labcorp RCV001221786 SCV001393848 uncertain significance Retinoblastoma 2020-05-27 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RB1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 597 of the RB1 protein (p.Gln597Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine.
