Labcorp Genetics (formerly Invitae), Labcorp RCV001897830 SCV002153559 uncertain significance Immunodeficiency 28 2022-07-05 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 223 of the IFNGR2 protein (p.Ile223Thr). This variant is present in population databases (rs764922061, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with IFNGR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1384821). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
