A few years ago, targeted NGS-based resequencing of the 25 most commonly mutated genes in myeloid leukemias/myelodysplasias revealed ASXL1, TET2, RUNX1, DNMT3A, EZH2 and TP53 mutations in 5 out 15 chronic phase CML patients at diagnosis [44]. Here, ASXL1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
