RUNX1 and acute lymphoblastic leukemia: When we focused on ZNF384/ZNF362-FM, PAX5-FM, and MEF2D-FM, which were recently reported as new subtypes in B-ALL [4–7, 17], we found that the incidences of these FG-FMs were second only to BCR-ABL1, and all exceeded the well-known ETV6-RUNX1 and TCF3-PBX1 in ALL (Table S4).
