Genes affected
RAG2 (HGNC:9832): (recombination activating 2) This gene encodes a protein that is involved in the initiation of V(D)J recombination during B and T cell development. This protein forms a complex with the product of the adjacent recombination activating gene 1, and this complex can form double-strand breaks by cleaving DNA at conserved recombination signal sequences. The recombination activating gene 1 component is thought to contain most of the catalytic activity, while the N-terminal of the recombination activating gene 2 component is thought to form a six-bladed propeller in the active core that serves as a binding scaffold for the tight association of the complex with DNA. A C-terminal plant homeodomain finger-like motif in this protein is necessary for interactions with chromatin components, specifically with histone H3 that is trimethylated at lysine 4. Mutations in this gene cause Omenn syndrome, a form of severe combined immunodeficiency associated with autoimmune-like symptoms. [provided by RefSeq, Jul 2008]
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 variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

Variant summary: RAG2 c.1504A>G (p.Met502Val) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0019 in 251354 control chromosomes in the gnomAD database, including 3 homozygotes. The observed variant frequency is approximately 3-fold of the estimated maximal expected allele frequency for a pathogenic variant in RAG2 causing Severe Combined Immunodeficiency Syndrome/Omenn Syndrome phenotype (0.00071), strongly suggesting that the variant is benign. c.1504A>G has been reported in the literature in individuals affected with Severe Combined Immunodeficiency Syndrome/Omenn Syndrome (e.g. Sobacchi_2006, Sheehan_2009, Walter_2015). In at least two of these individuals, co-occurrence of the variant in cis with a RAG1 pathogenic variant was reported (RAG1 c.1303A>G, p.Met435Val; Sheehan_2009, Walter_2015), providing supporting evidence for a benign role. Experimental evidence evaluating an impact on protein function demonstrated the variant to have wild-type levels of recombination activity (Tirosh_2019). Three ClinVar submitters (evaluation after 2014) cite the variant as benign/likely benign and five ClinVar submitters (evaluation after 2014) cite it as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign. -
