The 3111T/C polymorphism of the CLOCK gene confers a predisposition to a lifetime lower body weight in patients with anorexia nervosa and bulimia nervosa: a preliminary study.
These findings, although preliminary, suggest that the 3111T/C polymorphism of the CLOCK gene does not play a major role in the genetic vulnerability to AN and BN, but it seems to predispose eating disorders (EDs) patients to a more severe lifetime body weight loss.
