+8sole patients were older (p=0.013), presented lower WBC counts (p=0.010), harbored more often ASXL1 mutations (p<0.001) and RUNX1 mutations (p=0.009), but less frequent FLT3-ITD (p=0.038), NPM1 mutations (p<0.001) and double-mutated CEBPA (p=0.038) than NK patients.
CEBPA mutation status was not demonstrated to be of prognostic importance in this patient group, although this may reflect the selection and size of the AML population studied.

CEBPA mutations were reported exclusively in acute myeloid leukemia (AML) (according to WHO classification criteria) and mutated patients preferentially belonged to M1, M2 and M4 FAB subtypes.
CEBPA alterations in specific subgroups of AML comprise genomic mutations leading to dominant-negative mutant proteins, transcriptional suppression by leukemic fusion proteins, translational inhibition by activated RNA-binding proteins, and functional inhibition by phosphorylation or increased proteasomal-dependent degradation.
CEBPA mutations were found in 14/152 (9.2%) of acute myeloid leukemia (AML) patients' samples, 6/143 (4.2%) of MDS patients' samples, 2/56 (3.6%) of non-Hodgkin's lymphoma (NHL) patients' samples and 2/39 (5.1%) of multiple myeloma (MM) patients' samples.
CEBPA mutations and polymorphisms were determined in a large series of Southeast Asian AML (n = 247) using polymerase chain reaction and direct sequencing.
CCAAT/enhancer-binding protein alpha (C/EBPalpha) is mutated in 10% of acute myeloid leukemias, resulting in either a truncated protein or an altered leucine zipper (C/EBPalphaLZ) that prevents DNA binding.
CEBPA mutations cause a myeloid differentiation block and were detected in acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), multiple myeloma and non-Hodgkin's lymphoma (NHL) patients.
CEBPA mutations are of prognostic relevance in acute myeloid leukemia (AML) and are currently detected using a combination of denaturing high-performance liquid chromatography (DHPLC), gene scan/fragment length analysis, and direct Sanger sequencing.
CEBPA loss of-function mutations contribute to the development of ~10% of acute myeloid leukemia (AML), stablishing a tumor suppressor role for C/EBPα.
A C-terminal mutant of CCAAT-enhancer-binding protein α (C/EBPα-Cm) downregulates Csf1r, a potent accelerator in the progression of acute myeloid leukemia with C/EBPα-Cm.
