We also noted that APL patients share a similar immuno-phenotype of CD117 (P = 0.418), CD34 (P = 0.445), CD11b (P = 0.238), CD13 (P = 0.446), CD14 (P = 0.554), CD33 (positive in 100% cases), and MPO (P = 0.084) with non-APL patients. This evidence concerns the gene CD34 and acute promyelocytic leukemia.
