Acute promyelocytic leukemia (APL) is associated with 2 cardinal features: a granulocytic differentiation block and reciprocal and balanced translocations that always involve rearrangement of the RARA gene (180240). The most frequent translocation is t(15,17)(q21;q22), which fuses the RARA gene with the PML gene (102578) and represents more than 98% of APL (Vitoux et al., 2007). [from OMIM]
