Description : 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).;
