Abstract:

The somatic gain of function mutation V617F in Janus kinase 2 has been the point of interest in this study. This mutant allele is reported to be involved in a number of chronic forms of myeloid anomalies and rarely in acute myeloid leukemia (AML). We designed our study to identify this point mutation in AML patients (n=43) to understand its association with disease progression. We implemented allele specific oligonucleotide polymerase chain reaction for amplification of wild type and mutant allele. No individual was found positive to harbor the V617F mutation. This shows that many other known causes can be responsible for AML disease progression, but JAK2 V617F is a rare chance. The overall and event free survival rates of our patients were 59.06% and 23% respectively, after a follow up time of 18 months.

Keywords: Jak2 domain, V617F mutation, Acute myeloid leukemia (AML).
