As shown in Figure 6A, among the 834 AML patients, the MFI ratios of CD64 (Leukemia cells/Lymphocytes) in APL patients (mean, 95% confidence interval (CI): 18.30, 16.88−19.71) were significantly higher than those in non-APL patients (mean, 95% CI: 9.32, 7.68−11.0). The gene discussed is FCGR1A; the disease is acute myeloid leukemia.
