Overview

Myelofibrosis is a disorder of the bone marrow, in which the marrow is replaced by fibrous (scar) tissue.[1] When the bone marrow is scarred, it cannot make enough blood cells. This leads to anemia, weakness, fatigue, and often, swelling of the liver and spleen.[1][2] The condition occurs when blood stem cells develop somatic mutations in the JAK2, MPL, CALR, and TET2 genes. Other genes may also be involved. The condition is generally not inherited.[3] Although myelofibrosis can occur at any age, it typically develops after the age of 50.[1][2] In most cases, myelofibrosis gets progressively worse. Treatment is aimed at relieving signs and symptoms and may include medications, blood transfusions, chemotherapy, radiation therapy and surgery.[2]
