Acute promyelocytic leukaemia with a novel translocation t(16;17)(q12;p13): a case report.
Acute promyelocytic leukaemia (APML) is characterised by the t(15;17)(q22;q21), that results in the fusion of the promyelocytic leukaemia (PML) gene at 15q22 with the retinoic acid α-receptor (RARA) gene at 17q21. The current case report describes a 13-year-old male with APML, who was negative for PML/RARA fusion signal but reported to have an atypical translocation t(16;17). To the best of our...
متن کاملRecent advances in acute promyelocytic leukaemia
Acute promyelocytic leukaemia (APML) is a subtype of leukaemia arising from a distinct reciprocal translocation involving chromosomes 15 and 17, which results in the PML-RARA fusion gene. Over the past three decades, APML has been transformed from a highly fatal disease to a highly curable one. This drastic improvement is because of the introduction of a new treatment strategy with all-trans re...
متن کاملAcute promyelocytic leukemia cases with nonreciprocal PML/RARa or RARa/PML fusion genes.
Tumor-associated chromosome translocations usually lead to the formation of two reciprocal fusion genes: one thought to be involved in the transformation process, the other the mechanical consequence of the translocation event. In the case of acute promyelocytic leukemia (APL) blasts, the 15;17 chromosome translocation generates the putatively transforming PML/RARa fusion gene and its reciproca...
متن کاملFISH Detection of PML-RARA Fusion in ins(15;17) Acute Promyelocytic Leukaemia Depends on Probe Size
The diagnosis of acute promyelocytic leukaemia (APL) is usually confirmed by cytogenetics showing the characteristic t(15;17), but a minority of patients have a masked PML/RARA fusion. We report ten patients with APL and no evidence of the t(15;17), in whom the insertion of RARA into PML could not be demonstrated by initial FISH studies using a standard dual fusion probe but was readily identif...
متن کاملHigh-Risk Microgranular Acute Promyelocytic Leukemia with a Five-Way Complex Translocation Involving PML-RARA
Acute promyelocytic leukemia (APL) is classically characterized by chromosomal translocation (15;17), resulting in the PML-RARA fusion protein leading to disease. Here, we present a case of a 50-year-old man who presented with signs and symptoms of acute leukemia with concern for APL. Therapy was immediately initiated with all-trans retinoic acid. The morphology of his leukemic blasts was consi...
