NCI: Any process of gene rearrangement that creates a novel junction among the immunoglobuling-coding variable, diversity, joining or constant segments. This process involves sequence recognition, cleavage, excision and ligation by recombinases to create a contiguous protein-coding gene. Immunoglobulin gene rearrangement is involved in generation of antibody diversity.
