Genes affected

RAG1 (HGNC:9831): (recombination activating 1) The protein encoded by this gene is involved in activation of immunoglobulin V-D-J recombination. The encoded protein is involved in recognition of the DNA substrate, but stable binding and cleavage activity also requires RAG2. Defects in this gene can be the cause of several diseases.

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 624 of the RAG1 protein (p.Arg624Cys). This variant is present in population databases (rs199474688, gnomAD 0.01%). This missense change has been observed in individual(s) with Omenn syndrome (PMID: 11133745, 28783691, 31031743, 32655540). ClinVar contains an entry for this variant (Variation ID: 68686). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on RAG1 protein function. This variant disrupts the p.Arg624 amino acid residue in RAG1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 2808362, 16960852, 24290284). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
