Chronic myeloproliferative disorders (CMPDs) are clonal hematopoietic stem cell disorders, characterized by proliferation in the bone marrow of one or more of the myeloid (i.e., granulocytic, erythroid, and megakaryocytic) lineages. The proliferation is associated with relatively normal, effective maturation, resulting in increased numbers of granulocytes, red blood cells, and/or platelets in the peripheral blood. CMPDs are primarily diseases of adults.
