The t(15;17)(q22;q21) translocation is tightly linked to the APL phenotype, and the resultant PML-RAR fusion can be demonstrated in 98% of APL cases. Rare variant translocations have been reported, the majority of which on detailed analysis represent cryptic PML-RAR fusions. However, a handful of APL cases have been described with different genotypes. These include the t(11;17)(q23;q21) that produces the PLZF-RAR fusion, t(5;17)(q35;q21) that forms NPM-RAR, t(11;17)(q13;q21) that generates NUMA-RAR, and der(17) that creates STAT5b-RAR. In this review we will discuss these variant translocations, and discuss the insights that we have gained from their study.
t(15;17)(q22;q21)易位与急性早幼粒细胞白血病(APL)表型紧密相关,在98%的APL病例中均可检测到由此产生的早幼粒细胞白血病-维甲酸受体α(PML-RAR)融合基因。已有罕见变异易位的报道,经详细分析,其中大多数代表隐匿性PML-RAR融合。然而,也有少数具有不同基因型的APL病例被描述。这些包括产生早幼粒细胞白血病锌指蛋白-维甲酸受体α(PLZF-RAR)融合基因的t(11;17)(q23;q21)、形成核仁磷酸蛋白-维甲酸受体α(NPM-RAR)的t(5;17)(q35;q21)、产生核有丝分裂装置蛋白-维甲酸受体α(NUMA-RAR)的t(11;17)(q13;q21)以及产生信号转导和转录激活因子5b-维甲酸受体α(STAT5b-RAR)的17号染色体衍生染色体(der(17))。在本综述中,我们将讨论这些变异易位,并探讨我们从对它们的研究中获得的见解。
