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 lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 992 of the RAG1 protein (p.Lys992Glu). This variant is present in population databases (rs539590514, gnomAD 0.002%). This missense change has been observed in individuals with Omenn syndrome (PMID: 11313270, 18442948, 24290284). ClinVar contains an entry for this variant (Variation ID: 372488). 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. Experimental studies have shown that this missense change affects RAG1 function (PMID: 11313270, 24290284). For these reasons, this variant has been classified as Pathogenic. -

Published functional studies demonstrate a damaging effect (significantly reduced recombination activity) (PMID: 24290284, 11313270); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 11971977, 11313270, 31028937, 30877075, 34532947, 31672859, 18442948, 24290284, 34287245, 29410113, 26996199, 27825771) -

The RAG1 c.2974A>G variant is predicted to result in the amino acid substitution p.Lys992Glu. This variant has been reported in several individuals with RAG1 related disorders, some of which have had an additional deleterious variant within the RAG1 gene (Corneo et al. 2001. PubMed ID: 11313270; Lee et al. 2013. PubMed ID: 24290284; Table S1, Goda et al. 2018. PubMed ID: 29410113; Table S2, Schuetz et al. 2023. PubMed ID: 36279417; Strauss et al. 2008. PubMed ID: 18442948). This variant resides in a domain within the RAG1 gene that is required for a proper interaction with RAG2 (Corneo et al. 2001. PubMed ID: 11313270). Functional studies suggest this variant impairs function and results in abnormal VDJ recombination activity (Corneo et al. 2001. PubMed ID: 11313270; Lee et al. 2013. PubMed ID: 24290284). This variant is reported in 0.00089% of alleles in individuals of European (non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
