JAK2 exon 12 mutations were detected in 4 out of 20 polycythemia vera and idiopathic erythrocytosis V617F-negative patients and were only present in the myeloid lineage. Initial hematologic data of these patients differ from those of V617F-positive patients, but there is no difference in thrombotic development and myelofibrotic transformation.
Key words: JAK2 mutation, exon 12, V617F mutation, PV, erythrocytosis.
