PML-RARA

Promyelocytic leukemia (PML), is a gene that encodes for a transcription factor and tumor suppressor protein (Gene 2013a). PML is involved in rearrangements observed in AML, particularly APL (acute promyelocytic leukemia).

Retinoic acid receptor, alpha (RARA) is a gene that encodes for a nuclear retinoic acid receptor, a transcription regulating protein (Gene 2013b). In cancer, rearrangements involving RARA have been observed in AML and APL. Its role is also being investigated in gastric and other cancers.

The PML-RARA fusion has been observed in most cases of APL.

PML-RARA Fusion Gene in Acute Myeloid Leukemia

The PML-RARA fusion gene, t(15;17)(q24.1;21.1), is the primary cytogenetic abnormality leading to acute promyelocytic leukemia, a sub-type of AML. PML-RARA fusion proteins exhibit altered transcription factor behavior compared to wild type PML and RARA. Additional mutations may be required for leukemogenesis (Reiter, Lengfelder, and Grimwade 2004).​ PML-RARA fusion genes fall into class II of the “two-hit” theory of leukemogenesis (Naoe and Kiyoi 2013).
