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]

The S160L missense change represents a non-conservative amino acid substitution, as a polar Serine residue is replaced with a non-polar Leucine residue. This substitution occurs at a highly conserved position in RAG2 and is located in the core region of the protein, which is responsible for catalytic function. Therefore, S160L is a strong candidate for a pathogenic variant, which is further strengthened by the presence of the novel R73C mutation on the opposite allele in this particular individual. However, the possibility that S160L is a benign variant cannot be excluded. -
