Acute promyelocytic leukemia (APL) is characterized by a reciprocal translocation, t(15;17) (q22;q12), resulting in fusion of the genes promyelocytic leukemia (PML) and retinoic acid receptor alpha (RARA). With conventional cytogenetic methods, these translocations are detected in about 70-90% of pa
## Abstract We compared genomic breakpoints at the __PML__ and __RARA__ loci in 23 patients with therapyβrelated acute promyelocytic leukemia (tβAPL) and 25 de novo APL cases.Eighteen of 23 tβAPL cases received the topoisomerase II poison mitoxantrone for their primary disorder. DNA breaks were clu
