ReviewCardiovascular genomics, personalized medicine, and the National Heart, Lung, and Blood Institute: part I: the beginning of an era.
The inaugural issue of Circulation: Cardiovascular Genetics arrives at a remarkable time in the history of genetic research and cardiovascular medicine. Despite tremendous progress in knowledge gained, cardiovascular disease(CVD) remains the leading cause of death in the United States,1 and it has overcome infectious diseases as the leading cause of death worldwide.2 In addition, rates of CVD remain higher in black and Hispanic populations in the United States.1 The recent Strategic Plan of the National Heart, Lung,and Blood Institute (NHLBI) emphasizes research areas to fill the significant knowledge gaps needed to improve the diagnosis,treatment, and control of known risk factors and clinically apparent disease. ⋯ The National Institutes of Health (NIH) and the NHLBI are supporting a portfolio of large-scale genetic and genomic programs in diverse US populations with the longer-term objective of translating knowledge into the prediction, prevention, and preemption of CVD, as well as lung, sleep, and blood disorders. Underlying this portfolio is a strong commitment to make available participant-level data and aggregate research results to the broad community of investigators, while protecting the privacy and confidentiality and respecting the informed consent of study participants.

Genome-wide association analysis of high-density lipoprotein cholesterol in the population-based KORA study sheds new light on intergenic regions.
High-density lipoprotein cholesterol (HDLC) is a strong risk factor for atherosclerosis and is assumed to be under considerable genetic control. We aimed to identify gene regions that influence HDLC levels by a genome-wide association analysis in the population-based KORA (Cooperative Health Research in the Region of Augsburg) study. ⋯ The present genome-wide association study identified 2 interesting HDLC-relevant regions upstream of CETP and downstream of LIPG. This draws attention to the importance of long-range effects of intergenic regions, which have been underestimated so far, and may impact future candidate-gene-association studies toward extending the region analyzed. Furthermore, the present study reinforced CETP and LPL as HDLC genes and thereby underscores the power of this type of genome-wide association approach to pinpoint associations of common polymorphisms with effects explaining as little as 0.5% of the HDLC variance in the general population.
