Between 2005 and 2007, mutations in JAK2 and MPL were described in most patients with myeloproliferative neoplasms (MPN). These seminal discoveries have forever changed our diagnostic approach to MPN. In December 2013, mutations in CALR were reported in MPN wild-type for JAK2 and MPL. These mutations provide additional diagnostic and prognostic tools in MPN.
