The Environmental Polymorphisms Registry (EPR) is a long-term research project to collect and store DNA from up to 20,000 North Carolinians in a biobank. By donating blood to the project, you will help scientists discover changes in our genes as a result of environmental exposures that may increase or decrease our risk for common diseases, such as diabetes, heart disease, and cancer.

A study is being conducted for individuals with the autoimmune disease polymyositis or dermatomyositis. The goal of this research study is to better understand the environmental risk factors that may result in these diseases.
