RUNX1 and leukemia: Again, several of these genomic mutations were shared with T/M MPAL, including biallelic WT1 alterations, mutations of hematopoietic transcription factors (ETV6, RUNX1, CEBPA) and activating mutations of signaling pathways (JAK-STAT, FLT3, Ras) [92,163], supporting that they are similar entities in the spectrum of immature leukemias and both might have sensitivity to FLT3 and/or JAK inhibition [164].
