Labcorp Genetics (formerly Invitae), Labcorp RCV001309565 SCV001499067 uncertain significance Hypoproteinemia, hypercatabolic 2022-08-19 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 3 of the B2M protein (p.Arg3Cys). This variant is present in population databases (rs765817584, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with B2M-related conditions. ClinVar contains an entry for this variant (Variation ID: 1011724). 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"). 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.
