Labcorp Genetics (formerly Invitae), Labcorp RCV001933204 SCV002188831 uncertain significance Progressive sclerosing poliodystrophy 2022-08-12 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 570 of the POLG protein (p.Pro570Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with POLG-related conditions. ClinVar contains an entry for this variant (Variation ID: 1415682). 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"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
