Regarding the identification of antigens for the diagnosis of AML, they are classified as precursors (CD34, CD117, HLA-DR), myeloid markers (cMPO, CD33, CD13), myeloid maturation markers (CD11b, CD15, CD64, CD4, CD38, CD11c), monocytic markers (CD14, CD36, CD64), megakaryocytic markers (CD41, CD36, CD61), and erythrocyte markers (CD235, CD71, CD36) [14,57,60,61]. The gene discussed is CD33; the disease is acute myeloid leukemia.
