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.

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.78; 3Cnet: 3CNET). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with RAG1 -related disorder (PMID: 11133745). A different missense change at the same codon (p.Arg410Trp) has been reported to be associated with RAG1 -related disorder (ClinVar ID: VCV000859249/ PMID: 24290284). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense change has been observed in individuals with severe combined immunodeficiency, Omenn syndrome (PMID: 11133745, 24406074, 27609655, 31031743). This variant is present in population databases (rs199474684, gnomAD 0.004%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 410 of the RAG1 protein (p.Arg410Gln). ClinVar contains an entry for this variant (Variation ID: 68678). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg410 amino acid residue in RAG1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 24144642, 24290284, 24406074, 28769923). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Experimental studies have shown that this missense change affects RAG1 function (PMID: 24290284). 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 RAG1 protein function. -
