Pathogenetic role of JAK2 V617F mutation in chronic myeloproliferative disorders.
The molecular pathogenesis of chronic myeloproliferative disorders (MPDs) is poorly understood. The hematopoietic progenitor cells of patients with polycythemia vera (PV) or essential thrombocythemia (ET) are characterized by hypersensitivity to hematopoietic growth factors and formation of endogenous erythroid colonies. Recently, 4 groups reported almost simultaneously Janus kinase 2 (JAK2) V6...
متن کاملPrevalence of JAK2 V617F mutation in Indian patients with chronic myeloproliferative disorders.
BACKGROUND & OBJECTIVES The Janus-associated Kinase-2 mutation JAK2 V617F in chronic myeloproliferative disorders (CMPDs) has been described as a frequent genetic event in majority of patients with polycythemia vera (PV), essential thrombocythemia (ET) and idiopathic myelofibrosis (IMF). Its frequency varies in different populations but there are no data from India. We therefore, looked for JAK...
متن کاملDiagnostic assays for the JAK2 V617F mutation in chronic myeloproliferative disorders.
In 2005, multiple groups identified a high frequency of the V617F (G→T) mutation in the tyrosine kinase gene JAK2 as the most common molecular abnormality in chronic myeloproliferative disorders. Before 2005, there had been no recurring cytogenetic abnormality described at a high incidence in these disorders. The initial descriptions could well be classified as discovery papers because each gro...
متن کاملMegakaryocytic morphology in Janus kinase 2 V617F positive myeloproliferative neoplasm
CONTEXT Alterations in megakaryocyte morphology are the hallmark of myeloproliferative neoplasms (MPNs). These neoplasm are also associated with Janus kinase 2 (JAK2) V617F mutation in nearly 95% patients with polycythemia vera (PV), 40% patients of essential thrombocythemia (ET) and 50% patients of myelofibrosis (MF). The utility of megakaryocyte morphology in these disorders in correlation wi...
متن کاملWidespread occurrence of the JAK2 V617F mutation in chronic myeloproliferative disorders.
The analysis of rare chromosomal translocations in myeloproliferative disorders has highlighted the importance of aberrant tyrosine kinase signaling in the pathogenesis of these diseases. Here we have investigated samples from 679 patients and controls for the nonreceptor tyrosine kinase JAK2 V617F mutation. Of the 480 myeloproliferative disorder (MPD) samples, the proportion of positive cases ...
