Wernicke-Korsakoff syndrome is caused primarily by thiamine deficiency often due to alcohol use. Genetic variants affecting thiamine metabolism increase susceptibility.
How Genetic Is Wernicke-Korsakoff Syndrome?
Genetics plays a meaningful role in Wernicke-Korsakoff Syndrome, with heritability estimated at around 25%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Wernicke-Korsakoff Syndrome: TKTL1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
