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), LabcorpFeb 09, 2022This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 156 of the RAG1 protein (p.Ala156Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RAG1-related conditions. This variant is also known as c.579C>T. ClinVar contains an entry for this variant (Variation ID: 13142). 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. 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. -
