Labcorp Genetics (formerly Invitae), Labcorp RCV001969625 SCV002266265 uncertain significance Progressive sclerosing poliodystrophy 2022-02-19 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with POLG-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 254 of the POLG protein (p.Ser254Asn). 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.
