We report here the results of the GENIHUSS study (GENetic Investigation of Hypertension Undertaken in Sydney Sibships)-a genome-wide scan to identify loci linked to essential hypertension (HT). Subjects were Anglo-Celtic Australian sibpairs resident in or near Sydney, Australia, with onset of HT before age 60 years (mean, 44 +/- 13 SD years). A 10-cM scan involving 400 microsatellite markers and 252 HT sibpairs was followed by fine mapping of the most promising locus using 296 HT sibpairs (481 individuals from 200 families). Multipoint and two-point nonparametric linkage analyses were performed using MAPMAKER/SIBS, GENEHUNTER II, and SPLINK. Suggestive loci were found on chromosomes 1 (4 cM) and 4 (129 cM). The chromosome 4 locus coincided with a QTL for systolic blood pressure (BP) in the Australian Victorian Family Heart Study, and the locus on chromosome 1 contains the chloride channel gene CLCNKB and tumor necrosis factor receptor 2 gene TNFRSF1B, which have each shown association with HT. Our study adds to findings of HT loci emanating from genome scans.

We previously selected a group of hypertension candidate genes by a key word search using the OMIM database of NCBI and validated 525 coding single nucleotide polymorphisms (SNPs) in 179 hypertension candidate genes by DNA sequencing in a Japanese population. In the present study, we examined the association between 61 non-synonymous SNPs and blood pressure variations and hypertension. We used DNA samples taken from 1,880 subjects in the Suita study, a population-based study using randomly selected subjects. Analyses of covariance adjusting for age, body mass index, hyperlipidemia, diabetes, smoking, drinking, and antihypertensive medication revealed that 17 polymorphisms in 16 genes (APOB, CAST, CLCNKB, CTNS, GHR, GYS1, HF1, IKBKAP, KCNJ11, LIPC, LPL, P2RY2, PON2, SLC4A1, TRH, VWF) were significantly associated with blood pressure variations. Multivariate logistic regression analysis with adjustment for the same factors revealed that 11 polymorphisms in 11 genes (CAST, CTLA4, F5, GC, GHR, LIPC, PLA2G7, SLC4A1, SLCI8A1, TRH, VWF) showed significant associations with hypertension. Five polymorphisms in five genes, CAST(calpastatin), LIPC (hepatic lipase), SLC4A1 (band 3 anion transporter), TRH (thyrotropin-releasing hormone), and VWF (von Willebrand factor), were significantly associated with both blood pressure variation and hypertension. Thus, our study suggests that these five genes were susceptibility genes for essential hypertension in this Japanese population.
