Pediatric non-Down syndrome acute megakaryoblastic leukemia is characterized by distinct genomic subsets with varying outcomes

Franco Locatelli, Dirk Reinhardt, Marry van den Heuvel-Eibrink, C Michel Zwaan, Maarten Fornerod, Tanja Gruber and colleagues report whole-exome and transcriptome sequencing of acute megakaryoblastic leukemia from pediatric and adult patients without Down syndrome (non-DS-AMKL). They find that pediatric non-DS-AMKL can be divided into seven subgroups characterized by chimeric oncogenes with cooperating mutations in epigenetic and kinase signaling genes.
