Because biliary diseases are risk factors for cholangiocarcinoma and co-occur with them in our data, we tested whether SLC30A10 Thr95Ile was still associated with these biliary diseases, and the other selected quantitative traits and diagnoses, after removing the 148 individuals with extrahepatic bile duct cancer (Supplementary Table 9, Supplementary Table 10). This evidence concerns the gene SLC30A10 and cholangiocarcinoma.
