KMT2A and acute lymphoblastic leukemia: Of note, the ratio was significantly higher in cell lines with poor prognostic translocations such as Ph+ALL (median ratio; 32.1), MLL+ALL (79.3), and t(17;19)‐ALL cell lines (5000) than that in cell lines having favorable translocations such as t(1;19)‐ALL cell lines (11.2) and t(12;21)‐ALL cell lines (5.3), as well as other BCP‐ALL cell lines (8.2).
