Rs11887534

rs11887534, a SNP in the hepatic cholesterol transporter ABCG8 gene, has been implicated in gallstone disease, a process known formally as cholelithiasis. The common allele, rs11887534(G), encodes the aspartic acid (D), while the minor (C) allele encodes histidine (H).

In a study of ~1,000 German patients, the overall odds ratio associated with rs11887534(C) carriers was 2.2 (CI: 1.8-2.6, p=1.4x10-14), and for (C;C) homozygotes, 7x. Up to 10% of the population attributable risk for gallstones may be accounted for by this SNP.
