Labcorp Genetics (formerly Invitae), Labcorp	RCV002541293	SCV002952377	uncertain significance	Immunodeficiency 28	2025-01-08	criteria provided, single submitter	clinical testing	This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 148 of the IFNGR2 protein (p.Val148Met). This variant is present in population databases (rs766274599, gnomAD 0.006%). 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: 1328212). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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.
