New AdvancMolecular Pathogenand es in esis diagnosis of Essential Thrombocythemia
ABSTRACT
myeloproliferativneoplasm(MPN),is a hematopoietic diso

that is characterized clinically by thrombocytosis which results from bone marrow megakaryocyte hyperplasia.Patients with ET Essential thrombocythemia (ET),
a subtypof e
are at
increased risk for developing thrombosis,hemorrhage, myelofibrosis and transformato acutmyeloid leukemie
