This study aimed to evaluate the association of factor V Leiden (FVL), Janus kinase 2 (JAK2), prothrombin, and methylene tetrahydrofolate reductase (MTHFR) mutations with primary BCS.
The prevalence of the FVL and prothrombinG20210A mutations were compared between patients with Budd-Chiari syndrome or PVT without cirrhosis and healthy individuals (controls) and between patients with cirrhosis, with and without PVT.
The inherited deficiencies of protein C, protein S, antithrombin III, factor V Leiden mutation, prothrombin gene polymorphism, and antiphospholipids were studied in 53 Budd-Chiari syndrome (BCS) and 33 portal vein thrombosis (PVT) cases and compared with 223 age- and sex-matched controls.
