RCV003796928 | SCV004585491 | pathogenic | Combined immunodeficiency with skin granulomas; Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive | 2023-07-31 | 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 481 of the RAG2 protein (p.His481Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with severe combined immunodeficiency (PMID: 32445296). 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. This variant disrupts the p.His481 amino acid residue in RAG2. Other variant(s) that disrupt this residue have been observed in individuals with RAG2-related conditions (PMID: 12200379, 32445296, 33954879), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. |
