Genetic Polymorphisms Associated With CAD

Status Active, not recruiting

Clinical Trial Summary

The design and purpose of the current study is to expand and validate previous findings that the IL-1 gene cluster composite genotype patterns potentiate the risk for coronary artery disease (CAD) and cardiovascular events mediated by OxPL and Lp(a). A secondary objective is to validate other, non IL-1 genetic variants associated with CAD.

Clinical Trial Description

The conclusions from an earlier study indicate that the contribution of OxPL/apoB and Lp(a) on angiographically documented CAD and CAD events is conditional on proinflammatory IL-1 genotypes. This novel paradigm links the etiology of atherogenesis attributed to OxPL and Lp(a) from genetics to clinical expression of CAD. ILI has also identified the functional IL-1 gene variations that regulate the IL1B gene in a haplotype context and appear to explain over-expression of IL-1β, as well as the expression of other inflammatory biomolecules that are downstream of IL-1β. The functional IL-1 variants have been combined into patterns that have been associated with risk for more severe periodontal disease across multiple ethnic/racial populations. It is also important to test this functional genetic pattern for similar interactions with OxPL and Lp(a) biomarker levels in association with angiographically documented CAD and CAD events. DNA has been extracted from previously obtained subject blood samples (1173 subjects; 18 years to 90 years at entry (coronary angiography)) at the University General Hospital of Ioannina, Greece study site. DNAs will be labeled by anonymized subject ID # (de-identified), and shipped to ILI for genotyping and genetic analysis. Phase II will determine whether other gene variations (SNPs) previously shown in the literature to be associated with CAD and/or CAD-related secondary events can be validated in this study population. ;
