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.

In silico analysis supports that this missense variant does not alter protein structure/function; Observed in a patient with autoimmune neutropenia with a pathogenic variant in published literature, but it is not known whether the variants occurred on the same (in cis) or on different (in trans) chromosomes (Farmer et al., 2019); This variant is associated with the following publications: (PMID: 27825771, 30809743, 26884280, Baroudi-2019[Abstract], 30877075) -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 112 of the RAG1 protein (p.Arg112His). This variant is present in population databases (rs749223640, gnomAD 0.009%). 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: 427093). 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 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. -
