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. [provided by RefSeq, Jul 2008]

RAG2 (HGNC:9832): (recombination activating 2) This gene encodes a protein that is involved in the initiation of V(D)J recombination during B and T cell development. This protein forms a complex with the product of the adjacent recombination activating gene 1, and this complex can form double-strand breaks by cleaving DNA at conserved recombination signal sequences. The recombination activating gene 1 component is thought to contain most of the catalytic activity, while the N-terminal of the recombination activating gene 2 component is thought to form a six-bladed propeller in the active core that serves as a binding scaffold for the tight association of the complex with DNA. A C-terminal plant homeodomain finger-like motif in this protein is necessary for interactions with chromatin components, specifically with histone H3 that is trimethylated at lysine 4. Mutations in this gene cause Omenn syndrome, a form of severe combined immunodeficiency associated with autoimmune-like symptoms. [provided by RefSeq, Jul 2008]

ACMG classification

Specifications for RAG1 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Our verdict: Benign. The variant received -8 ACMG points.

• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 59 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Gene score misZ: 0.5811 (below the threshold of 3.09). Trascript score misZ: 1.7677 (below the threshold of 3.09). GenCC associations: The gene is linked to Omenn syndrome, severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive, combined immunodeficiency due to partial RAG1 deficiency, immunodeficiency disease, recombinase activating gene 1 deficiency.
• BP4: Computational evidence support a benign effect (MetaRNN=0.014743745).
• BP6: Variant 11-36576320-A-G is Benign according to our data. Variant chr11-36576320-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 536963.
• BS2: High Homozygotes in GnomAdExome4 at 5 AR gene
