Summary

Solute carrier organic anion transporter family member 1B1 (SLCO1B1) is an important hepatic uptake transporter that can transport a wide variety of endogenous compounds, including thyroid hormones and prostaglandin E2. Dysregulation of thyroid hormones and prostaglandin E2 plays a role in the development of hypertension, suggesting that SLCO1B1 might contribute to the aetiology of essential hypertension (EH). In this study, we selected five single nucleotide polymorphisms (SNPs) at the SLCO1B1 gene promoter or coding regions and performed a case-control association study involving 731 unrelated Uyghur subjects, including 374 hypertensive and 357 normotensive individuals, to investigate the potential genetic contribution of SLCO1B1 to the aetiology of EH. Of the five polymorphisms, only one (i.e., rs4149014) showed correlation with EH. The minor allele of SNP rs4149014 at the SLCO1B1 promoter showed association with increased risk for EH (adjusted OR 1.88; 95% CI 1.36–2.60; P= 1.22 × 10−4). This study provides preliminary genetic evidence for the role of variant of SLCO1B1 in the susceptibility to human EH in Uyghurs.
