JAK2 mutation in patients with splanchnic venous thrombosis: A pilot study from India.

The article discusses a study in India which analyzed the presence of the Janus Kinase 2 (JAK2) V617F mutation in patients with thrombosis with no signs of overt myeloproliferative neoplasms (MPN). Blood samples were obtained from 32 patients who had portal vein thrombosis (PVT) and from 20 patients who had hepatic vein thrombosis (HVT). The study has identified JAK V617F mutation in six patients among 32 with PVT and four among the 20 patients with HVT.
