Invitae RCV001036026 SCV001199369 uncertain significance PMM2-congenital disorder of glycosylation 2021-08-30 criteria provided, single submitter clinical testing This sequence change replaces proline with arginine at codon 20 of the PMM2 protein (p.Pro20Arg). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with PMM2-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: "Possibly 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.
