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.

RAG1 Gene-Disease associations (from GenCC):

• immunodeficiency disease

  Inheritance: AR Classification: DEFINITIVE Submitted by: Ambry Genetics
• Omenn syndrome

• recombinase activating gene 1 deficiency

  Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
• severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive

  Inheritance: AR Classification: STRONG, SUPPORTIVE Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae), Orphanet
• combined immunodeficiency due to partial RAG1 deficiency

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• 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.
