Carriers of the CG genotype of ABCG8rs11887534 had higher risk of biliary stones [odds ratio (OR) = 2.3, 95% confidence interval (CI) 0.82-6.5), gallbladder cancer (OR = 4.3, 95% CI 1.7-10.4) and bile duct cancer (OR = 1.94, 95% CI 0.64-5.91), compared with carriers of the GG genotype.
We observed that in our population the ABCG8 DH genotype frequency was significantly higher in GBC patients [P=0.011; odds ratio (OR)=1.79; 95% confidence interval (CI)=1.1-2.8].
