[Clonal evolution in myeloproliferative neoplasms].
Recent advances in sequencing technologies have clarified the driver gene landscape in Philadelphia chromosomenegative (Ph-) myeloproliferative neoplasms (MPNs) and progressed understanding of MPN pathogenesis. Beyond mutations in the main three drivers of MPN, namely JAK2, MPL and CALR, somatic mutations in the epigenetic regulators and RNA splicing factors have been identified and their association with transformation to myelofibrosis and acute myeloid leukemia have been determined. Clonal expansion of hematopoietic cells with driver mutations (clonal hematopoiesis) has been detected in healthy individuals, especially in elderly people. In MPN patients, however, initial driver mutations such as those in JAK2 and DNMT3A have been shown to be acquired in utero or during childhood. In this review, I will summarize the recent findings about clonal evolution in MPN and the role of driver mutations.
