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 submitter | clinical testing | Invitae | Jan 20, 2019 | 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. 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"). This variant has not been reported in the literature in individuals with RAG1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tryptophan with arginine at codon 28 of the RAG1 protein (p.Trp28Arg). The tryptophan residue is highly conserved and there is a moderate physicochemical difference between tryptophan and arginine. - |
