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 glutamine, which is neutral and polar, at codon 34 of the RAG1 protein (p.Arg34Gln). This variant is present in population databases (rs377307948, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with RAG1-related conditions. ClinVar contains an entry for this variant (Variation ID: 536958). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
