Somatic mutations in CALR gene, which encodes endoplasmic reticulum chaperone Calreticulin, were found in majority of patients with Myeloproliferative neoplasms without JAK2 mutation. Insertions or deletions in exon 9 of CALR were detected in 67% of patients with essential thrombocythemia (ET) and 88% of those with primary myelofibrosis (PMF), but rarely detected in patients with polycythemia vera. This assay was designed to detect all types of insertions and deletions in exon 9 of CALR that has been reported. .
