Invitae RCV000535436 SCV000646380 uncertain significance Combined immunodeficiency with skin granulomas; Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive 2022-03-09 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 468 of the RAG2 protein (p.His468Arg). This variant is present in population databases (rs751064709, gnomAD 0.0009%). 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: 469118). 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.
Illumina Laboratory Services, Illumina RCV001103960 SCV001260782 uncertain significance Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
