title: Linkage disequilibrium analysis of the renin-angiotensin system genes.
abstract: The genes of the renin-angiotensin system (RAS) are important candidates to confer susceptibility to cardiovascular diseases. A large number of association studies between cardiovascular traits and the polymorphisms in RAS have been conducted, although inconsistent results are often reported. The patterns of linkage disequilibrium in RAS genes have also been reported in different populations. However, our understanding of the genetic architecture underlying the RAS is still limited despite rapid progress in empiric studies regarding the patterns of the human genome as a whole. In this review, the linkage disequilibrium among the polymorphisms within the four RAS genes and current association analyses involving the RAS are discussed, as well as some of the gaps of knowledge and possible solutions.
