The study seeks to understand how levels of plant sterols in the blood differ between participants with one or zero copies of an altered sterol transporter gene. To date, over 300 Amish volunteers have provided blood samples. Our findings suggest that individuals with one copy of the changed sterol transporter gene are not at increased risk for heart disease.
