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 histidine, which is basic and polar, at codon 396 of the RAG1 protein (p.Arg396His). This variant is present in population databases (rs104894291, gnomAD 0.005%). This missense change has been observed in individuals with Omenn syndrome (PMID: 9630231, 17075247, 19830075). This variant is also known as G1299A. ClinVar contains an entry for this variant (Variation ID: 13146). Invitae Evidence 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 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. Experimental studies have shown that this missense change affects RAG1 function (PMID: 9630231, 21131235, 24290284). For these reasons, this variant has been classified as Pathogenic. -
