Objective:To investigate the detection of in patients with acute myeloid leukemia and its clinical value.Methods:Detection of FIP1L1-PDGFRA gene mutation for 86 patients with acute myeloid leukemia in peripheral blood using nested PCR.Results:There 6 patients with acute myeloid leukemia had FIP1L1-PDGFRA gene mutation,including 3 cases of M4 EO,2 cases of M2,1 cases of M5.Conclusion:FIP1L1-PDGFRA gene mutation can be detected among patients with acute myeloid leukemia,and most of its type was M4 EO.
