Aberrant breakpoints in chronic myelogenous leukaemia; oncogenes and fragile sites

Three hundred and twenty-five aberrant breakpoints in chronic myelogenous leukaemia (CML) with Philadelphia chromosome variant were reviewed. Eight chromosomal bands (3p21, 6p21, 7p22, 11q13, 12p13, 17p13, 17q21, and 17q25) were found to be highly involved. Apart from 17q25, all these bands correspond to oncogenes sites and/or sites involved as primary breakpoints in cancer.
