In line with previous multiomics studies from us and others [8, 9, 19], we demonstrated the expression of the well-described AML-associated antigens CD33 (SIGLEC3), CD38, CD123 (IL3RA) and CD371 (CLL1 or CLEC12A) as well as less frequently CD135 (FLT3) in primary pediatric AML. The gene discussed is CD33; the disease is acute myeloid leukemia.
