Abbreviations: AKIP1, A‐kinase interacting protein 1; AML, acute myeloid leukemia; CEBPA, CCAAT/enhancer‐binding protein α; FAB classification, French‐American‐British classification; FLT3‐ITD, internal tandem duplications in the FMS‐like tyrosine kinase 3; NPM1, nucleophosmin; SD, standard deviation.
High or low expression of AKIP1 was classified by the median value of AML patients.
