Invitae RCV000685966 SCV000813468 uncertain significance Combined immunodeficiency with skin granulomas; Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive 2022-08-15 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 270 of the RAG2 protein (p.Glu270Gly). This variant is present in population databases (rs149241274, gnomAD 0.03%). 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: 566212). 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 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.
PreventionGenetics, part of Exact Sciences RCV003411595 SCV004113280 uncertain significance RAG2-related disorder 2023-03-30 criteria provided, single submitter clinical testing The RAG2 c.809A>G variant is predicted to result in the amino acid substitution p.Glu270Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.037% of alleles in individuals of Latino descent in gnomAD ( At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
