title: The genetics of eating disorders.
abstract: The eating disorders anorexia nervosa and bulimia nervosa traditionally have been viewed as sociocultural in origin. However, recent behavioral genetic findings suggest substantial genetic influence on these disorders. Molecular genetic research of these disorders is in its infancy, but initial results are promising. This article reviews findings from family, twin, and molecular genetic studies that support substantial genetic influences on disordered eating and highlights additional areas for future research.
