Labcorp Genetics (formerly Invitae), Labcorp RCV000631283 SCV000752311 uncertain significance Chuvash polycythemia; Von Hippel-Lindau syndrome 2017-10-13 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. 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 VHL-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with glycine at codon 213 of the VHL protein (p.Asp213Gly). The aspartic acid residue is weakly conserved and there is a moderate physicochemical difference between aspartic acid and glycine.
