Brief Summary

The Anorexia Nervosa Genetics Initiative (ANGI) is the largest and most rigorous genetic investigation of eating disorders ever conducted. Researchers in the United States, Sweden, Australia, and Denmark will collect clinical information and blood samples from over 13,000 individuals with anorexia nervosa and individuals without an eating disorder. ANGI represents a global effort to detect genetic variation that contributes to this potentially life-threatening illness. The goal of the research study is to transform knowledge about the causes of eating disorders to work toward greater understanding and ultimately a cure. If you have suffered from anorexia nervosa at any point in your life, you can help us achieve this goal. Your contribution would include a brief questionnaire and a blood sample. If you have never had anorexia nervosa, but still want to contribute, we invite your participation as well.

Biospecimen

Retention: SAMPLES WITH DNA

The blood sample participants provide will be used to identify biological characteristics and other biological "markers." Some analyses will include genetic analyses which are measured using DNA and can look at places in DNA, and others can analyze most of the genome. Other analyses measure a large number of proteins. Still others assess the messenger substance (called RNA) that transfers information from DNA to protein. Investigators plan to store the blood specimens and data indefinitely. Investigators will be collecting DNA to permit immediate and future genetic analyses and analyses of immune, endocrine, and proteins. All blood will be biobanked indefinitely to allow for assays that may become available in the future analyses.
