In this study, we sought to identify genetics polymorphisms in Ara-C and dNTP metabolic pathway including CMPK1, NME1/NME2 (encoding NDPK), SAMHD1, RRM1, RRM2 and E2F1 with drug response to Ara-C based chemotherapy and AML prognosis in Chinese AML patients. The gene discussed is CMPK1; the disease is acute myeloid leukemia.
