Labcorp Genetics (formerly Invitae), Labcorp RCV001905077 SCV002130225 uncertain significance Progressive sclerosing poliodystrophy 2021-09-01 criteria provided, single submitter clinical testing This sequence change replaces glutamine with glutamic acid at codon 86 of the POLG protein (p.Gln86Glu). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and glutamic acid. This variant is not present in population databases (ExAC no frequency). 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: "Tolerated"; 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.
