title: Linkage analysis of five candidate genes and essential hypertension in 106 Chinese nuclear families.
abstract: Five candidate genes including the lipoprotein lipase, leptin, leptin receptor, alpha-adducin and beta3 adrenergic receptor were selected to examine their possible contribution to essential hypertension (EH) in a Chinese population. On each side of the candidate gene loci, one to two highly polymorphic microsatellite markers were genotyped in 474 subjects recruited from 106 hypertension nuclear families in Shanghai. Both parametric and nonparametric linkage analyses were carried out using GENEHUNTER (version 2.0) after genotyping. Extended transmission disequilibrium testing (ETDT) was also conducted to detect preferential transmission of alleles to affected offspring. We failed to find the linkage between all these loci and EH by either parametric or nonparametric analysis, nor did we detect any significant transmission disequilibrium by ETDT. Our findings provide no support for a significant contribution of these five genes to the pathogenesis of EH among Shanghai people.
