Invitae RCV000817293 SCV000957844 uncertain significance Combined immunodeficiency with skin granulomas; Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive 2022-09-06 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 418 of the RAG2 protein (p.Thr418Ile). This variant is present in population databases (rs781487639, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with RAG2-related conditions. ClinVar contains an entry for this variant (Variation ID: 660163). 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 not expected to disrupt RAG2 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.
