Gallstones have a significant hereditary component estimated at 25–30%. Genes affecting cholesterol metabolism and bile salt transport are implicated.
How Genetic Is Gallstones?
Genetics plays a meaningful role in Gallstones, with heritability estimated at around 25%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Gallstones: ABCG8,ABCB11,LITH1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
