Recent studies have shown that a variant TATA\u2010box in the promoter region of the UDP\u2010glucuronosyltransferase 1A1 (UGT1A1) gene is associated with the development of cholelithiasis. The coding region mutation (G71R) of the UGT1A1 gene was higher in Asians than those in Caucasians. The relationship between the variant UGT1A1 promoter and coding region gene and cholelithiasis in \u03b2\u2010thal\/Hb E subjects were investigated.<\/jats:p><jats:p><jats:bold>Methods:\u00a0<\/jats:bold> One hundred and seventeen \u03b2\u2010thal\/Hb E subjects entered this study. The TATA\u2010box and G71R mutations were analyzed by fragment size analysis and restriction fragment length polymorphism methods, respectively.<\/jats:p><jats:p><jats:bold>Results:\u00a0<\/jats:bold> The incidence of cholelithiasis was higher in heterozygous (68.3%) and homozygous (100%) subjects compared with normal UGT1A1 haplotype (61.4%). Total bilirubin level (6.0\u2003\u00b1\u20032.03\u2003mg\/dL) in the homozygous group was significantly higher than that of wild type (3.31\u2003\u00b1\u20031.83\u2003ng\/dL). Prevalence of cholelithiasis increased with age (OR\u2003=\u20031.1, 95% CI\u2003=\u20031.03\u20131.12, <jats:italic>P<\/jats:italic>\u2003&lt;\u20030.001).
