We have identified a rare BCR-ABL chimaeric gene with multiplex and nested RT-PCR in a patient with an unusually aggressive chronic myeloid leukaemia. cDNA sequencing showed an in-frame rearrangement with a breakpoint in BCR exon e13 (b2) and fusion with ABL exon 3 following skipping of the entire ABL exon a2. These data confirm the heterogeneity of breakpoints in BCR-ABL rearrangements.
我们通过多重巢式逆转录聚合酶链反应（RT-PCR）在一名患有异常侵袭性慢性髓性白血病的患者中鉴定出一种罕见的BCR-ABL嵌合基因。cDNA测序显示在BCR外显子e13（b2）处发生读码框内重排，且在整个ABL外显子a2缺失后与ABL外显子3融合。这些数据证实了BCR-ABL重排中断点的异质性。
