These results suggest that the JAK2-V617F mutation occurs after the onset of monoclonal haematopoiesis; thus the V617F mutation of JAK2 may not be the primary event in the induction of BCS.
We report the case of a young patient with a coagulation disorder secondary to a mutation of factor V Leiden, who presented with upper digestive bleeding as the first manifestation of Budd Chiari syndrome and who also was associated with myocardial infarction in his past medical history.
Factor V Leiden was the most common risk factor, i.e., 14 of 53 (26.4%) in BCS cases followed by protein C, as compared with PVT cases, i.e., 2 of 33 (6.06%) and controls, i.e., 5 of 223 (2.3%).
Associations of coagulation factor V Leiden and prothrombin G20210A mutations with Budd-Chiari syndrome and portal vein thrombosis: a systematic review and meta-analysis.
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.
Here, a 22 year old female with angiographically proven BCS secondary to JAK2/V617F positive Polycythemia vera on therapeutic warfarin presented with acute liver failure (ALF).
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.
By resolving the sensitivity bias of the JAK2 mutation with the results of BM histology and clonality assay, CMPD was diagnosed in 53% of patients with EHPVO or BCS.
A clonal mutation in JAK2 tyrosine kinase (JAK2V617F) occurs in a high proportion of patients with MPD and is of use in the characterization of latent MPD in BCS.
Determination of the JAK2V617F mutation may be useful to recognize patients with Budd-Chiari syndrome with or at risk for the subsequent development of overt myeloproliferative diseases.
The purpose of this study was to use JAK2V617F analysis to re-evaluate the validity of elevated Epo levels as a PV-exclusion criterion in patients with hepatic vein thrombosis [Budd-Chiari syndrome (BCS)].
The incidence and clinical outcomes of JAK2 mutations, novel ten-eleven translocation 2 (TET2) mutations, and the 46/1 haplotype in BCS are unknown for liver transplantation (LT).
The cause of the BCS still being unknown, in October 1996 we performed extensive laboratory investigations concerning states of thrombophilia and found moderately elevated IgG anticardiolipin antibodies (19.7 U/ml) and a resistance against activated protein C caused by heterozygosity for a point mutation of the factor V gene (1691G-->A; factor V Leiden).
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.
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.
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.
