Abstract

TO THE EDITOR:

The JAK2 V617F mutation is the most common somatic mutation in the classical myeloproliferative neoplasms (MPNs), present in >95% of cases of polycythemia vera (PV) and ∼50% of essential thrombocythemia (ET) and myelofibrosis (MF).1⇓⇓-4 It is usually the sole identifiable driver mutation in MPNs5 and was recently also identified as a driver of age-related clonal hemopoiesis in healthy individuals.6⇓⇓-9 In order to investigate the preclinical clonal evolution of MPNs, we identified 12 individuals with a JAK2 V617F mutant MPN, who 4.6 to 15.2 years previously (median 10.2 years) had also donated blood to register with the Cyprus Bone Marrow Donor Registry at the Karaiskakio Foundation
