Labcorp Genetics (formerly Invitae), Labcorp RCV001215865 SCV001387632 uncertain significance Retinoblastoma 2019-05-30 criteria provided, single submitter clinical testing 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, 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 RB1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with valine at codon 525 of the RB1 protein (p.Ala525Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. 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.
