Eating Disorders (ED)

Workgroup Chairs: Cynthia Bulik and Gerome Breen

ED Data Access Portal

The eating disorders workgroup has been a part of the PGC since 2013. During that time, our membership has grown to include investigators from over 20 countries spanning North America, Europe, Asia, and Australasia. Our group focuses on the study of anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Drs. Cynthia Bulik (University of North Carolina at Chapel Hill and Karolinska Institutet, Stockholm, Sweden) and Gerome Breen (King’s College London, UK) chair our group. Our interdisciplinary membership includes graduate and postdoctoral trainees in psychiatric genetics as well as distinguished faculty in psychiatry, biostatistics, genetics and related fields. We are currently working toward uniting researchers and clinicians from around the world to create the largest collection of DNA from individuals with AN in the world. Our current goals are to rapidly increase sample size and conduct an adequately powered GWAS of anorexia nervosa. We aim to identify causal loci for this often lethal disorder in order to understand the underlying biology and ultimately to effect better treatment.

Members of the workgroup stay connected through regular conference calls on the first Thursday of every month and via our workgroup listserve. Please contact Virpi Leppä if interested in learning more about the conference calls. If you are a member of the eating disorders workgroup and have questions about a specific analysis or if you are interested in joining an ongoing approved secondary analysis project, please contact the investigator leading that project.

We are an open and welcoming group. If you have samples from patients with eating disorders and would like to join the group and have your samples genotyped, please contact us. If you are interested in hearing more, please contact either or
