These disorders are driven by gain-of-function mutations in the genes Janus kinase 2 (JAK2), calreticulin (CALR), or the thrombopoietin receptor (MPL) that activate cytokine signaling. These mutations arise decades before clinical disease develops and confer a clonal advantage that is further shaped by comutations in epigenetic, splicing, or signaling genes. Inflammation enhances clonal dominance, favoring the development of myelofibrosis and thrombotic complications.
