Increased frequency of rare damaging variants in PLIN4 in patients with anorexia nervosa

Background

Anorexia nervosa (AN) is a severe psychiatric disorder characterized by pathological fear of weight gain, persistent restriction of energy intake, and pervasive body image disturbance. Although AN is substantially heritable, the rare coding variants contributing to susceptibility remain incompletely defined. Pedigree-based whole-exome sequencing studies can help to identify rare, high-effect protein-coding variants and thereby elucidate disease mechanisms.
