What can at-home genetic tests tell you about heart-related risks?

At-home genetic tests such as 23andMe and Ancestry Health are unlikely to help predict a person’s odds of heart disease. The results reveal only limited information about a person’s risk for abnormally high cholesterol (a condition known as familial hypercholesterolemia) or harmful blood clots (known as hereditary thrombophilia). Most cases of coronary artery disease, the most common form of heart disease, are polygenic, meaning they result from changes in multiple genes.
