Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP7BS1

This summary comes from the ClinGen Evidence Repository: The NM_000536.4:c.1095T>C variant is a synonymous (silent) variant (p.Ser365=) with no predicted splice impact (BP7). This variant has not been reported in the literature in individuals with RAG2-related conditions. The highest population minor allele frequency in gnomAD v2.1.1 is 0.00314 (79/25120) in the Finnish population, which is higher than the ClinGen SCID VCEP's threshold for BS1 (>0.00195). In summary, this variant meets the criteria to be classified as Likely Benign for autosomal recessive SCID based on the ACMG criteria applied BS1 and BP7, as specified by the ClinGen SCID VCEP (VCEP specifications 1).

Genes affected

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]

RAG2 links:

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.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
