CALR Ex9 Indel by PCR

Minimum of 3 mL whole blood in a purple (EDTA) or pink top tube (EDTA); minimum of 1 mL of bone marrow aspirate in a purple, pink, or green (heparin) top tube.

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.
