The t(15;17)(q24;q21) translocation is the defining genetic event in Acute Promyelocytic Leukemia (APL). It fuses the Promyelocytic Leukemia (PML) gene on chromosome 15 with the Retinoic Acid Receptor Alpha (RARA) gene on chromosome 17. The resulting PML-RARA fusion protein functions as an aberrant transcriptional repressor that blocks myeloid differentiation. This knowledge led to the revolutionary use of all-trans retinoic acid (ATRA) and arsenic trioxide as targeted differentiation therapy, making APL one of the most curable forms of acute leukemia.
