  4. Study Overview

The Environmental Polymorphisms Registry 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.

Who Can Participate?

  • Adults and children 8 years of age or older

What Is Required?

  • Small blood sample (approximately 1 tablespoon)
  • Periodically update contact information
  • Agree to volunteer for follow-up studies based upon your genotype, health, or disease status
  • You can receive up to $20 for participating

Who Is Running the Study?

The study is run by physicians at the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health in collaboration with exercise scientists at UNC.

Interested in Hosting Recruitment Events?

If you are a corporation, church, community group or other organization of any type, and would like to host a recruitment event, please contact Jamie R. Glover at 919-287-4382. If your organization holds employee health fairs, it would be a good opportunity for employees to learn more about environmental diseases and participate in research.
