“…In 98% of APL patients, a balanced translocation between chromosomes 15 and 17 [t(15;17) (q22;q21)] was found, which leads to the formation and fusion of promelocytic leukemia protein (PML) and retinoic acid receptor alpha (RARα) [30,31]. A variety of chromosomal aberrations have been identified in APL including t(11;17)(q23;q21), t(5;17)(q35;q12-21), t(11;17)(q13;q21), and der (17), in which the RARα gene is fused to the PLZF, NPM, NuMA, and STAT5b genes, respectively [32]. The differentiation of leukemic cells and complete remission of APL may occur after treatment with ATRA (all-trans retinoic acid).…”
