Hepatic vein obstruction often associated with myeloproliferative disorders. JAK2 V617F mutation is found in ~40% of cases.
How Genetic Is Budd-Chiari Syndrome?
Genetics plays a meaningful role in Budd-Chiari Syndrome, with heritability estimated at around 30%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Budd-Chiari Syndrome: JAK2. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
