Abstract

The eating disorders are severe psychiatric illnesses with significant morbidity and mortality that exhibit statistically significant familial risk and heritability, providing support for a molecular genetic approach toward defining etiological factors. An emerging candidate gene literature has concentrated on serotinergic and dopaminergic candidates. With the financial support of the Price Foundation, a group of investigators initiated an international multi-center collaboration (Price Foundation Collaborative Group) in 1995 to study the genetics of anorexia and bulimia nervosa by collecting and analyzing phenotypes and genotypes of individuals and their relatives affected with eating disorders. The first sample of families collected by this collaborative group, known as the Price Foundation Anorexia Nervosa Affected Relative Pair (AN-ARP) dataset, was ascertained on an proband affected with Anorexia Nervosa (AN), with relative pairs affected with the eating disorders AN, Bulimia Nervosa or Eating Disorders Not Otherwise Specified [1]. Biognosis U.S., Inc. was founded to identify and characterize candidate susceptibility genes for anorexia and bulimia nervosa phenotypes in the Price Foundation eating disorder datasets. During 2000-2001, Biognosis U.S., Inc. developed and implemented a research program with a focus on the analysis of candidate genes nominated by neurochemical characteristics of eating disorder patients [2], serotonergic and dopaminergic candidate gene polymorphisms [3], neuroendocrine regulation of appetite [4], and by a positional hypothesis from a linkage analysis of the AN-ARP dataset [5]. This report reviews the anorexia nervosa candidate gene literature through 2001, the candidate gene research program implemented at Biognosis U.S., Inc. and selected candidate gene findings in the AN-ARP dataset derived from that research program.
