Abstract
BACKGROUND Gallstone disease (GD) is common but remains asymptomatic in most cases. However, gallstones can lead to complications like choledocholithiasis or gallbladder cancer. In this study, we analyse the common genetic risk factor for GD, the p.D19H variant in the sterol transporter ABCG8, in Polish patients with gallstones and gallbladder cancer. METHODS Three adult cohorts were prospectively recruited: 65 patients with gallbladder cancer, 170 obese individuals scheduled for bariatric surgery and 72 patients who underwent endoscopic retrograde cholangiopancreatography due to recurrent choledocholithiasis. The control cohort consisted of 172 gallstone-free adults. The ABCG8 p.D19H (rs11887534) polymorphism was genotyped using TaqMan assays. RESULTS The minor allele frequency (MAF) of the ABCG8 p.D19H polymorphism was significantly (p = .02) higher among cases with either gallstones or gallbladder cancer (MAF = 8.4%) as compared to controls (MAF = 4.0%). The highest frequency of the risk allele was detected in patients with gallbladder cancer (18.5%) and obese patients with GD (17.5%), followed by individuals with choledocholithiasis (13.9%). Notably, the p.19H variant was associated with an increased risk of developing gallbladder cancer (OR 2.76, 95% CI 1.16-6.54, p = .01) and an increased risk of GD in obese individuals scheduled for bariatric surgery (OR = 2.70, 95% CI 1.05-6.49, p = .03), but did not significantly affect the risk of choledocholithiasis. CONCLUSIONS The ABCG8 p.D19H common risk variant increases the risk of developing gallbladder cancer in Central Europeans and enhances the risk of gallstones in the obese. Carriers of the p.D19H variant might benefit from personalized preventive strategies, particularly regarding gallbladder cancer.
