Brief Summary

To investigate the genetics of C reactive protein in families with myocardial infarction.

Detailed Description

BACKGROUND:

Coronary artery disease (CAD) and myocardial infarction (MI) are the leading causes of death in the Western world. Numerous epidemiological studies have demonstrated the impact of various risk factors, such as arterial hypertension, hypercholesterolemia and diabetes mellitus. While these risk factors are partly under genetic control, a positive family history remains an additional independent predictor of CAD, suggesting the presence of as yet unidentified susceptibility loci. Given the enormous public health burden of CAD, there is significant interest in identifying its specific genetic foundations. As intensive experimental investigations continue, the inflammatory component of the disease process leading to atherosclerosis evolves as a key aspect in the disease process. Recent evidence demonstrates that systemic markers of inflammation such as C reactive protein (CRP) can predict those at high risk of coronary events. CRP emerges with much attention as both a diagnostic marker and therapeutic target with serum levels determined to a significant extent by genetic factors.

DESIGN NARRATIVE:

To elucidate the genetic basis of the inflammatory component of myocardial infarction and the regulation of C reactive protein, a gene function oriented evaluation of candidate genes will be conducted. Therefore the specific aims are as follows, 1. Identify positional candidate genes within regions identified for MI and CRP which are functionally related to inflammation and inflammatory processes. Sequence variation in selected candidate genes will be identified. 2. Evaluate the effect of these variants with regard to MI and CRP in two different ethnic populations: a family set of European Caucasians and a population-based, Hispanic family dataset. The role of CRP will be evaluated as a predictor of cardiovascular events in the study populations. Since clinical follow up data are available on both study populations, the extent to which CRP contributes to an increased risk for cardiovascular events will be analyzed.
