Abstract
- Hypertension is an important risk factor for chronic kidney disease. The kidney, in turn, has an important role in the regulation of blood pressure (BP). On the basis of a genome-wide association study, single-nucleotide polymorphisms in the uromodulin (UMOD) promoter region had been considered to influence both renal sodium reabsorption and BP. In this study, we asked whether common variants across the UMOD gene influence BP in a community-based Chinese cohort. We screened seven common variants across the UMOD locus in a community-based population from Beijing, including 1000 individuals with 48% males and an average age of 63.7±9.0 years. The urinary UMOD concentration was measured by enzyme-linked immunosorbent assay. We then analyzed the association of common variants of UMOD with BP. The UMOD promoter common variant rs13333226 G/A is associated with diastolic BP (DBP), and G allele carriers have higher DBP compared with A/A homozygotes (P=0.035). The variant rs6497476 C/T predicted the DBP level, with C homozygotes having a higher DBP compared with CT heterozygotes and T homozygotes (P=0.025). Urinary UMOD excretion was correlated with urinary sodium excretion (R=0.239, P=0.656*10(-13)). We determined that common variants of UMOD are associated with DBP level in a community-based Chinese cohort.
