Characterization of three new imatinib-responsive fusion genes in chronic myeloproliferative disorders generated by disruption of the platelet-derived growth factor receptor beta gene.
Whole-exome sequencing and cluster analysis demonstrated the presence of three distinct major clones during the clinical course: (1) an AMoL clone with ASXL1, CBL, and NPM1 somatic mutations, likely associated with the pathogenesis, and GATA2, SRSF2, and TET2 mutations, (2) an AMoL remission clone, with mutated GATA2, SRSF2, and TET2 only (possibly the founding clone (pre-leukemic HSC) that survived chemotherapy), (3) a small subclone which had JAK2 mutation during the AMoL remission, appearing at MPN-U manifestation with additional mutations.

Our result showed that the positive rate of any of four mutations in patients with PV, ET, PMF, and MPN-U was 89.3%, 83.4%, 87.2%, and 77.5%, respectively, which significantly improved the diagnostic rate, especially in ET and PMF.
