A cryptic inv(16)(p13.3q24.3) encoding the CBFA2T3-GLIS2 fusion is associated with poor outcome in infants with acute megakaryocytic leukemia. We aimed to broaden our understanding of the pathogenesis of this fusion through transcriptome profiling. Experimental Design: Available RNA from children and young adults with de novo AML (N=1,049) underwent transcriptome sequencing (mRNA and miRNA).
