Identification of atherosclerosis-modifying genes: pathogenic insights and therapeutic potential.
Atherosclerosis is a common, complex trait, with genetic variation in many genes and the environment contributing to risk for this condition, which has multiple and highly variable phenotypic manifestations. Progress has been made in the identification of atherosclerosis-modifying genes in both human studies and through the use of animal models. In the future, it may be possible to administer a genetic test for variation in a handful of the most common atherosclerosis-modifier genes, and thus predict if a patient is likely to develop atherosclerosis and ischemic heart disease. These patients could then be treated aggressively to lower their low-density lipoprotein cholesterol levels and other risk factors, including counseling to make adjustments in their lifestyle. This review will summarize the methods and results thus far in the identification of atherosclerosis-modifier genes.
