Labcorp Genetics (formerly Invitae), Labcorp RCV001927229 SCV002158049 uncertain significance Progressive sclerosing poliodystrophy 2021-11-17 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1092 of the POLG protein (p.Phe1092Leu). This variant is present in population databases (rs74034411, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with POLG-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.
