Invitae RCV001054222 SCV001218526 uncertain significance PMM2-congenital disorder of glycosylation 2022-01-14 criteria provided, single submitter clinical testing This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 187 of the PMM2 protein (p.Trp187Arg). This variant is present in population databases (rs781346472, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with PMM2-related conditions. ClinVar contains an entry for this variant (Variation ID: 850123). 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 disruptive. 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.
