Authors: Zhiyuan Wu, Chen Zhang, Xiaochao Ma, Ming Guan

Abstract

In late 2013, somatic mutations in calreticulin (CALR), mainly those involving insertions and deletions in exon 9, attracted the great attention of hematologists and researchers. These JAK2- and MPL- mutual exclusive mutations enjoy a favorable specificity and prevalence (20-30%) in patients with essential thrombocythemia (ET) and primary myelofibrosis (PMF), suggesting promise for these mutations in disease management. Moreover, these genetic variations are now also considered as a group of independent risk factors for disease prognosis. In this mini-review, we will document the value of CALR mutations in disease diagnosis, prognosis, and therapeutic strategy selection, and we will discuss current advances in methods to detect these mutations.
