This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goal of this project is to contribute to our understanding of the genetic basis of hypertension(HTN) in African-Americans(AA). Hypertension disproportionately affects AA and its complications contribute immensely to health disparity experienced by AA through increased morbidity from stroke,heart failure, kidney failure and coronary heart disease. It is now accepted that HTN results from a complex interplay between genetic and environmental factors.However, the environmental risk factors, which include lifestyle, dietary and psycho-social factors, have been better characterized than the genetic ones. Linkage and candidate gene studies have so far provided limited success across studies and population groups. Building on the success of a previously funded study of the genetic epidemiology of AA families in the Washington DC metropolitan area, we propose to enroll a population sample of HTN cases and unaffected controls, genotype a panel of ancestry informative markers(AIM) in the sample and utilize the admixture mapping approach to identify genomic regions associated with HTN.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 这个项目的目标是帮助我们了解非洲裔美国人AA高血压 HTN的遗传基础。高血压对AA的影响不成比例，其并发症通过增加中风、心力衰竭、肾衰竭和冠心病的发病率，极大地促进了AA所经历的健康差异。高血压病是遗传因素和环境因素相互作用的结果，但环境因素（包括生活方式、饮食和心理社会因素）比遗传因素更易被发现。连锁和候选基因研究迄今为止在研究和人群中取得的成功有限。 基于先前资助的华盛顿DC大都市区AA家族遗传流行病学研究的成功，我们建议招募HTN病例和未受影响的对照人群样本，对样本中的一组祖先信息标记物AIM进行基因分型，并利用混合物作图方法鉴定与HTN相关的基因组区域。
