Abstract: Essential thrombocyhtemia is a BCR-ABL negative myeloproliferative disorder (MPD) distinct from polycytemia vera and idiopathic myelofibrosis and characterized by persistent thrombocytosis, excessive proliferation of megakariocytes in the bone marrow, normal erythrocytic mass and the absence of prominent bone marrow fibrosis. In the last few years new information on pathogenesis of myeloproliferative disorders became available: the discovery of an acquired recurrent molecular abnormality in the 14th exon of the JAK2V617F gene resulting in a substitution of valine for phenylalanine at position 617 in the JAK2 protein (V617). We analyzed the recently identified JAK2V617F mutational status, the relevance of mutated allele burden for clinical presentation, thrombosis and hemorrhagic complications.
