One key benefit of participating in the PGP is the opportunity to help researchers learn more about diseases that have a genetic component, including muscular dystrophy, sickle cell anemia, Huntington's disease, diabetes, addictions, obesity, mental illnesses, Down syndrome, and many more. The data that the PGP will gather hold the promise for better diagnosis, therapy, and prevention of these diseases. Although individual participants will not receive clinical data or medical advice, their participation in the project may mean better medical care in the future for thousands of people afflicted with genetic diseases.
