Clinical Significance
Helps physicians diagnose and predict the course of disease progression for hematologic diseases.

In the updated WHO Classification of Hematologic Malignancies (2016), the major diagnostic criteria for several different myeloproliferative neoplasms require the presence of specific gene mutations with supporting clinical and morphologic features. The JAK2 V617F mutation is found in virtually all cases of Polycythemia Vera (PV), with rare cases harboring a JAK2 exon 12 mutation. Mutations in JAK2 V617F, MPL codon 515 and CALR exon 9 are also major diagnostic criteria for Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF). Activating mutations in CSF3R (e.g T618I) are now included as diagnostic criteria for Chronic Neutrophilic Leukemia (CNL). Furthermore, SETBP1 mutations are found in a subset of BCR-ABL1 negative, atypical Chronic Myeloid Leukemia, (aCML) cases that lack mutations in JAK2, MPL, and CALR. The release of the v. 2.2017 NCCN Guidelines for MPNs further recommend testing for gene mutations in ASXL1, EZH2, IDH1, IDH2 and SRSF2 for risk stratification in primary myelofibrosis.
