Labcorp Genetics (formerly Invitae), Labcorp RCV001366636 SCV001562945 uncertain significance MHC class I deficiency 2022-06-17 criteria provided, single submitter clinical testing This variant is present in population databases (rs371802164, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 226 of the TAP2 protein (p.Arg226Gln). This variant has not been reported in the literature in individuals affected with TAP2-related conditions. 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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: "Not Available"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1057617).
