Abstract

Detection and diagnosis of the myeloproliferative neoplasms (MPNs) are difficult to predict without screening for genetic causes, including polycythemia vera (PV), essential thrombocythemia (ET), primary myelofibrosis (PMF) and chronic myeloid leukemia (CML). A novel mutation in the Janus kinase 2 (JAK2) gene has been described as a genetic marker prime for all four-types of MPNs. The specific c.1851G>T (p.V617F) mutation leads to constitutively activetyrosine kinase activity of JAK2, inducing downstream JAK/STAT pathways of cytokine signaling. The existence of the JAK2(c.1851G>T; p.V617F) mutation has a clinical importance in diagnosis of MPNs. In this study, amplification refractory mutation system (ARMS) assay for a specific mutation detection was utilized, which is an Allele Specific Oligonucleotide (ASO) based multiplex PCR method. Genomic DNA samples were isolated from total blood samples from suspected MPN patients, who visited Hiwa hospital (the main teaching hospital for cancer in Sulaimani city). The aim of this study was to screen for JAK2 mutation c.1851G>T (p.V617F) on a group of suspected patients for MPNs (100 patients). The result shows that 65% of patients had indeed c.1851G>T mutation and the rest 35% of patients were normal for the mutation. In this study, we have shown the ARMS assay method to be quick, simple, cheap, reliable, and gives sufficient sensitivity for positive detection compatible for clinical diagnostic purposes. Therefore, the assay can be used for early diagnosis of MPNsin diagnostic laboratories with limited resources, such as in our health care system in our locality.
