According to the old adage, "you dont get something for nothing." This is certainly the case for the novel genetic mechanisms involved in adaptive immunityV(D)J recombination, class-switch recombination (CSR), and somatic hypermutation (SHM). These mechanisms allow animals to respond with great specificity to a seemingly limitless array of rapidly evolving microbes and their products while investing a relatively small amount of genetic capacity. The cost, however, is genomic instability and its potential contribution to malignancy. A majority of B- and T-cell leukemias and lymphomas are associated with chromosomal abnormalities that bear the hallmarks of aberrant V(D)J or class-switch recombination. In
