Identification of JAK2 (V617F) mutation in Myeloproliferative Neoplasms by using Allele Specific Polymerase Chain Reaction (AS-PCR)

Myeloproliferative neoplasms (MPNs) is a group of clonal haematopoietic stem cell disorders characterized by the proliferation of one or more myeloid cell lineages. According to WHO classification, the Janus associated kinase 2 (JAK2) V617F mutation is the one of the major diagnostic criteria in BCR-ABL1 negative myeloproliferative neoplasms .The aim of this study is to detect the JAK2 (V617F) mutation in patients with myeloproliferative neoplasms to get accurate diagnosis and proper management. A total of 90 clinically diagnosed MPN patients attending to Department of Clinical Haematology ,Yangon General Hospital were enrolled in this study. The mean age was 53.4 ± 14 years which ranged from 16 to 81 years old and male and female ratio was 2.4:1. The identification of JAK2 (V617F) point mutation was found to be positive in 44/90 MPN patients (48.9%).
