Labcorp Genetics (formerly Invitae), Labcorp RCV001923345 SCV002184396 uncertain significance Retinoblastoma 2021-08-14 criteria provided, single submitter clinical testing This sequence change replaces arginine with lysine at codon 272 of the RB1 protein (p.Arg272Lys). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and lysine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with RB1-related conditions. 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. 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.
