Polycythaemia vera (PV) belongs to the group of myeloproliferative neoplasms with excessive increase in hemoglobin levels. They are clinically characterized by nonspecific symptoms such as fatigability, pruritus, early satiety due to splenomegaly, increased risk of infections, and thrombotic events. JAK2 V617F mutation present in 80-90% of MPNs and JAK2 exon12 mutations are seen in 4%-5% cases of MPNs like PV. Activation of JAK2 by either point mutation or fusion protein causes activation of the JAK-STAT pathway. While mutations in JAK2 are reported in numerous MPN phenotypes, exon 12 mutations specifically result in erythrocytosis due to increased EPO signaling. Conclusion: All three cases that presented to the department had been undiagnosed for 2-3 months before they reached our setup. The unique feature of all these cases was negativity for both JAK2V617F as well as JAK2 exon 12 mutation despite its clinical behavior being that of PV .These cases are being actively managed as low risk polycythemia vera and since the start of the treatment comprising of phlebotomy once very 3 months their hemoglobin and hematocrit concentrations are maintained. No cytoreductive therapy is being given .Such unique presentations need to be reported and discussed extensively
