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.
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 presence of JAK2V617F in both ECs and hematopoietic cells belonging to BCS patients with PV indicates that ECs from these patients are involved by the malignant process and that in this subpopulation of patients the disease may originate from a cell common to hematopoietic and endothelial cells.
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.
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.
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.
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)].
