Abstract
Genes that can be implicated in hypertension in experimental animals are plausible candidates in the pathogenesis of human hypertension. A recent genome-wide search for quantitative-trait loci (QTL) in hypertensive rats revealed a strong correlation between the interleukin-6 (IL-6) locus on rat chromosome 4 and systolic, diastolic, and mean arterial pressure in this mammalian species. To investigate a possible association between genetic variations of the IL-6 gene and hypertension in humans, we identified two novel single-nucleotide sequence variations, a C/G substitution at -634 in the promoter region and a G/A substitution at 4391 in a 3' non-coding portion of exon 5, and a previous reported sequence variant, an A/T variation in the composition of the AnTn tract around -447 in the promoter region (Fishman D et al. J Clin Invest 1998; 102: 1369-1376), within a test population of 96 Japanese subjects. Allelic associations involving these variations were analyzed in 150 hypertensive and 143 normotensive Japanese women. The distribution of alleles of the three polymorphisms, as well as a dinucleotide repeat present at the IL-6 locus, was similar in the two groups. Therefore, the IL-6 gene appears to play a minimal role in the genetic etiology of essential hypertension in Japanese women.
