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.

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 29, 2023In 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. 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 not expected to disrupt RAG1 protein function. ClinVar contains an entry for this variant (Variation ID: 469115). This missense change has been observed in individual(s) with Omenn syndrome (PMID: 18442948). This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 277 of the RAG1 protein (p.Lys277Arg). -
