APEX1, a novel, negative regulator of aldosterone synthase activity, differentially binds to a single nucleotide polymorphism in the aldosterone synthase gene and represses transcriptional activity both in vitro and in vivo

McManus Frances , Sands William , Fraser Robert , Davies Eleanor , Connell John

Aldosterone synthesis is heritable; a single nucleotide polymorphism (SNP) in the promoter of the aldosterone synthase gene (position −344, rs1799998) has been associated with an increased plasma aldosterone levels and hypertension. However, deletion of this site has no effect on gene transcription in vitro and therefore the mechanism that links genotype with phenotype is unclear.We identified a polymorphism at position −1651 T/C (rs13...

Variation in the aldosterone synthase gene may alter gene transcription via altered transcription factor binding

McManus Frances , Sands William , Davies Eleanor , Connell John

The aldosterone synthase gene encodes the final step in the production of aldosterone. The aldoststerone synthase gene is polymorphic and variants within the gene and the regulatory region have been associated with hypertension and a phenotype of relatively higher level of aldosterone and its metabolites. However to date; none of the polymorphisms in the regulatory region of CYP11B2 have been shown to alter transcription. Seven novel polymorphisms in the promoter region of CYP...
