Role of JAK2 in the pathogenesis and therapy of myeloproliferative disorders
The myeloproliferative disorders polycythaemia vera (PV), essential thombocythaemia (ET),
and primary myelofibrosis (PMF) are clonal disorders of multipotent haematopoietic
progenitors. The genetic cause of these diseases was not known until 2005, when several
independent groups demonstrated that most patients with PV, ET and PMF acquire a single
point mutation in the cytoplasmic tyrosine kinase JAK2 (JAK2V617F). These discoveries
have changed the landscape for diagnosis and classification of PV, ET and PMF, and show …

Abstract
The myeloproliferative disorders polycythaemia vera (PV), essential thombocythaemia (ET), and primary myelofibrosis (PMF) are clonal disorders of multipotent haematopoietic progenitors. The genetic cause of these diseases was not known until 2005, when several independent groups demonstrated that most patients with PV, ET and PMF acquire a single point mutation in the cytoplasmic tyrosine kinase JAK2 (JAK2V617F). These discoveries have changed the landscape for diagnosis and classification of PV, ET and PMF, and show the ability of genomic technologies to identify new molecular targets in human malignancies with pathogenetic, diagnostic and therapeutic significance.
