A versatile team of doctors and scientists at the Center for Celiac Research at Massachusetts General Hospital, MassGeneral Hospital for Children, and the Celiac Program at Harvard Medical School created the CDGEMM study to learn more about each of the many factors that contribute to the development of celiac disease. This long-term, multi-center study will follow infants from birth through childhood with visits that can be conducted at your local pediatrician’s office. Infants can even be enrolled before birth!
