The Anorexia Nervosa Genetics Initiative (ANGI), an initiative of The Klarman Family Foundation, was at the time the largest and most rigorous genetic investigation of eating disorders ever conducted. Dr. Cynthia Bulik at the University of North Carolina at Chapel Hill was the lead investigator of ANGI with collaborators from Karolinska Institutet, Stockholm, Sweden (Dr. Mikael Landén), Aarhus University, Aarhus, Denmark (Dr. Preben Bo Mortensen), and Berghofer Queensland Institute for Medical Research, Brisbane, Australia (Dr. Nick Martin) with assistance from the University of Otago, Christchurch, New Zealand (Drs. Martin Kennedy and Jenny Jordan).

ANGI represented a global effort to detect genetic variation that contributes to this potentially life-threatening illness. In total, ANGI collected biological samples and clinical information from 13,363 individuals with anorexia nervosa as well as healthy controls who were matched by ancestry and geography.

Recruitment for ANGI is currently closed. A series of blog posts describes the results and meaning of the ANGI study.

The ANGI team is grateful to all participants worldwide, to the research teams in the USA, Europe, and Australasia who helped create this unprecedented resource, and to all of the clinicians, researchers, bloggers, journalists, family members, advocates, and individuals with lived experienced who joined us in our collaborative effort to make ANGI a reality.
