Summary Recent advances in sequencing technologies have allowed for the identification of recurrent mutations in acute myeloid leukaemia (AML). The transcription factor CCAAT enhancer binding protein alpha ( CEBPA ) is frequently mutated in AML, and biallelic CEBPA ‐mutant AML was recognised as a separate disease entity in the recent World Health Organization classification. However, CEBPA mutations are co‐occurring with other aberrations in AML, and together these lesions form the clonal hierarchy that comprises the leukaemia in the patient. Here, we aim to review the current understanding of co‐occurring mutations in CEBPA ‐mutated AML and their implications for disease biology and clinical outcome. We will put emphasis on patterns of cooperation, how these lesions cooperate with CEBPA mutations and the underlying potential molecular mechanisms. Finally, we will relate this to patient outcome and future options for personalised medicine.
