WebSep 19, 2024 · The key difference between somatic hypermutation and V(D)J recombination is that somatic hypermutation is a process that allows B cells to mutate their genes to produce high-affinity antibodies, while V(D)J recombination is a process of somatic recombination that happens during the lymphocyte development in order to generate … WebDefects in V (D)J recombination underlie a wide range of diseases ranging from immunodeficiencies and autoimmunity to cancer. Human SCIDs result either from defects in T cell development (70%–80% of SCIDs) or defects in both T and B cell development (20%–30% of SCIDs). The latter disease, T − B − SCID, generally results from V (D)J ...
