AMP case report: Acute promyelocytic leukemia with cryptic t(15;17) identified by RT-PCR
April 2019—Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML) in which promyelocytes predominate. APL accounts for about 10 percent of AML cases, and although APL can be diagnosed at any age, it is most common among young adults with a slight male predominance. APL is defined by the balanced reciprocal translocation (15;17)(q22;q21) between PML and RARA, although variant translocations involving RARA and other partner genes can occur.
