Characterization of CEBPA Mutations in Acute Myeloid Leukemia: Most Patients with CEBPA Mutations Have Biallelic Mutations and Show a Distinct Immunophenotype of the Leukemic Cells

These data revealed that most AML with CEBPA mutations were associated with an immunophenotype of HLA-DR(+)CD7(+)CD13(+)CD14(-)CD15(+)CD33(+)CD34(+). The close relationship of CEBPA mutations with the leukemia status of the patients and the concordance of mutation in presenting and relapse samples implicate the CEBPA mutation as a potential marker for monitoring minimal residue disease.
