Genomic and transcriptional features of AMTL. Sixty-three cases spanning AML, AUL, MPAL, and ETP immunophenotypes shared a common transcriptional identity (see Fig. 1B). A, Mutational spectrum of AMTL cases. Del, deletion; Ins, insertion; LOH, loss of heterozygosity. B, Outcomes of patients with AMTL according to FLT3-ITD and PRC2 transcriptional identity. Dx, diagnosis; pOS, probability overall survival. C, Outcomes of FLT3-ITD/WT1 double-mutant cases based on AMTL and MK-V transcriptional identity (see Fig. 1). D, Expression of HOX locus genes in normal hematopoietic progenitor subsets and FLT3-ITD/WT1 cases from AMTL and MK-V transcriptional clusters. CMP, common myeloid progenitor; HSCP, HSC progenitor; LP, lymphoid-restricted progenitor. E, Enrichment of gene-expression signatures from HSC, CMP, and LP in FLT3-ITD/WT1 cases from AMTL and MK-V transcriptional clusters. n.s., not significant. F, pLSC6 score of FLT3-ITD/WT1 cases from AMTL and MK-V transcriptional clusters.
