One category of mutations prevent CCAAT/enhancer-binding protein alpha DNA binding by altering its COOH-terminal basic leucine zipper domain.
CEBPA mutations, which result in diminished CCAAT/enhancer-binding protein alpha activity, contribute to the transformation of myeloid antecedents.
[12] It has been shown that mutation of CEBPA has been linked to good outcome in both adult and pediatric acute myeloid leukemia patients.
It has been shown that suppression of CEBPA expression and blocking of CCAAT/enhancer-binding protein alpha stops the differentiation of myeloid progenitors.
Mutation of the CEBPA gene has been shown to play a crucial role in leukemogenesis and prognosis in acute myeloid leukemia patients.
[16][17] A recent study has found that higher levels of CEBPA methylation are directly proportionate with treatment response.
