Labcorp Genetics (formerly Invitae), Labcorp RCV002009573 SCV002288955 uncertain significance Immunodeficiency 28 2023-11-13 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 290 of the IFNGR2 protein (p.Gln290Pro). This variant is present in population databases (rs143025663, gnomAD 0.02%). 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: 1507747). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt IFNGR2 protein function with a positive predictive value of 80%. 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.
