Abstract
We have shown that the incidence of complex translocations is approximately the same in chronic myeloid leukemia, characterized by the t(9;22)(q34;q11), and in acute myeloid leukemias, characterized by the t(15;17)(q22;q11) or t(8;21)(q22;q22). This incidence is almost threefold greater than the incidence of complex translocations in lymphomas and lymphoid leukemias characterized by the t(8;14)(q24;q32) or t(14;18)(q32;q21). The genomic recombination, which gives rise to the translocations in lymphoid cells, results mostly from errors of IGH gene rearrangement. Genomic recombination underlying myeloid leukemias has a different cause, and a clue to this may lie in the greater incidence of complex chromosome rearrangements.
