Next, molecular typing of B-ALL was implemented using ALLSorts, with the following results: DUX (4, 4%), ETV6-RUNX1 (12, 10%), ETV6-RUNX1-like (2, 2%), high hyperdiploid (38, 33%), KMT2A group (9, 8%), low hypodiploid (1, 1%), MEF2D (4, 4%), NUTM1 (2, 2%), PAX5 P80R (1, 1%), PAX alt (5, 5%), Philadelphia chromosome positive (Ph+, 4, 4%), Ph-like (5, 5%), TCF3-PBX1 (11, 10%), ZNF384 (1, 1%), and unclassified (13, 12%). This evidence concerns the gene MEF2D and acute lymphoblastic leukemia.
