![]() Recombination activating genes ( RAG-1 and RAG-2 ) play a fundamental role by initiating the cut-and-paste process leading to the assembling of the V, (D), and J segments, which together form the variable portion of the receptors. These recombination signal sequences consist of a heptamer sequence (CACAGTG), directly adjacent to the coding element, and a nonamer element (ACAAAACC), separated from the heptamer by a spacer of either 12 or 23 base pairs.Įfficient recombination occurs between a pair of gene elements with recombination signal sequences that have different spacer lengths, the so-called 1223 rule. Rearrangement is directed by recombination signal sequences that flank each antigen receptor gene segment. ![]() V(D)J recombination is the process leading to the generation of variable domains through the assembly of one segment each from a set of variable (V), joining (J), and, in some cases, diversity (D) subgenic elements. It is reported here that the clinical and immunologic phenotypes of patients bearing mutations in RAG s are more diverse than previously thought and that this variability is related, in part, to the specific type of RAG mutation.Īnalysis of the RAG genes by direct sequencing is an effective way to provide accurate diagnosis of RAG -deficient as opposed to RAG -independent V(D)J recombination defects, a distinction that cannot be made based on clinical and immunologic phenotype alone.
