Location, location, location: A mini-review of CEBPA variants in patients with acute myeloid leukemia.

CEBPA variants are frequently recurring in acute myeloid leukemia (AML). The prognostic significance of CEBPA mutations has recently undergone a major shift in the 5th edition of WHO classification of hematological neoplasms and ELN 2022 classification. Whereas prior iterations did not specify the type of CEBPA mutation, the updated schema specify that only mutations localized to the C-terminal basic zipper (bZIP) domain are considered prognostically favorable. This change is based primarily on three recently published large datasets evaluating the prognostic significance of mutation location in CEBPA mutant AML. Here, we review the evolution of the prognostic classification of CEBPA variants.
