We describe a patient with acute promyelocytic leukemia (APL) carrying a new complex variant translocation of t(2;15;17)(q21;q22;q21). The karyotypic interpretation was confirmed by fluorescence in situ hybridization (FISH) with the use of painting probes of chromosomes 2, 15, and 17 and a PML/RARA dual color DNA probe. FISH showed a PML/RARA fusion gene on the der(2) instead of the der(15). These results suggest that the critical event in the development of APL is the formation of a PML/RARA chimeric gene, regardless of its locus in the genome.
我们描述了一名患有急性早幼粒细胞白血病（APL）的患者，其携带一种新的复杂变异易位t(2;15;17)(q21;q22;q21)。通过使用2号、15号和17号染色体的涂染探针以及PML/RARA双色DNA探针进行荧光原位杂交（FISH），证实了核型解释。FISH显示在der(2)上而非der(15)上存在PML/RARA融合基因。这些结果表明，APL发生发展中的关键事件是PML/RARA嵌合基因的形成，而不论其在基因组中的位置如何。
