The functional role of AdipoQ in appetite control has been a major focus for biomedical research as the genetic variants in AdipoQ can be linked with modifications/abnormalities in human eating behavior (66) and notable changes in serum AdipoQ have been reported in patients with eating disorders, e.g., with elevated levels in patients with anorexia nervosa whereas the opposite is true for binge eating (67). The gene discussed is ADIPOQ; the disease is anorexia nervosa.
