The numbers of genes, actually probe sets, in each list were: 712 for the upper group composed of acute lymphoblastic leukemia (ALL) and mixed-lineage Leukemia (MLL), which we call ALL-MLL list; 3 for the upper group composed of ALL and acute myelogenous leukemia (AML), which is termed as ALL-AML list; 100 for the upper group composed of MLL and AML (MLL-AML list). Here, KMT2A is linked to acute lymphoblastic leukemia.
