Labcorp Genetics (formerly Invitae), Labcorp RCV002014374 SCV002298768 uncertain significance D-2-hydroxyglutaric aciduria 2 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 188 of the IDH2 protein (p.Arg188Gln). 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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 1511129). This variant has not been reported in the literature in individuals affected with IDH2-related conditions. This variant is present in population databases (rs749096156, gnomAD 0.01%).
