ABSTRACT
<p><b>OBJECTIVE</b>To investigate possible association between the single nucleotide polymorphisms (SNPs) of transforming growth factor beta3 (TGF-beta3) gene and essential hypertension (EH) in Chinese.</p><p><b>METHODS</b>The promoter region, exons, as well as part of the introns of TGF-beta3 gene were sequenced by a fluorescent labeling automatic sequencing method to detect and characterize the SNPs in 24 DNA samples from a Chinese population. Then we conducted a case-control study using 396 patients with hypertension (case) and 214 nomortensive subjects (control). The three SNPs including Thr63Asn, SS5608219 and SS5608220 were genotyped by PCR-RFLP or real-time allele-specific PCR in subjects studied.</p><p><b>RESULTS</b>Seven SNPs in the exons, introns and 3'untranslated region (3'UTR) of TGF-beta3 gene were identified. Among them, 2 SNPs were found to be novel genetic variants and one of the two located in the exon 1 and produced substitution of amino acid. However, no differences were found between hypertensives and nomortensives in genotype distribution and allele frequency of SS5608219, Thr63Asn or SS5608220 polymorphisms.</p><p><b>CONCLUSIONS</b>Two novel SNPs of TGF-beta3 gene were identified in Chinese. One of them produces a threonine to asparagines substitution in codon 63 (Thr63Asn). But no association was found between TGF-beta3 gene polymorphisms and EH in Chinese.</p>
