PY - 2011 T2 - Williams Manual of Hematology, 8e AB - Polycythemia vera (PV) is a clonal disorder due to somatic mutations of a multipotential hematopoietic cell, in which blood cell production, notably erythropoiesis, is increased independent of cytokine regulation. This results in exaggerated proliferation and accumulation of erythrocytic, granulocytic, and megakaryocytic cells. PV is one of the chronic myeloproliferative disorders (MPDs): essential thrombocythemia (ET), primary myelofibrosis (PMF), and chronic myelogenous leukemia (CML); these disorders are also called myeloproliferative neoplasms (MPN).Three myeloproliferative neoplasms (PV, ET, PMF) share a common molecular abnormality/marker, the JAK2 kinase V617F mutation.
