Labcorp Genetics (formerly Invitae), Labcorp RCV002296752 SCV002595473 uncertain significance Retinoblastoma 2022-09-07 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 disruptive. This variant has not been reported in the literature in individuals affected with RB1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces arginine, which is basic and polar, with threonine, which is neutral and polar, at codon 150 of the RB1 protein (p.Arg150Thr).
