The genetics of alcoholisms and related disorders.
The inheritance of alcohol abuse and other psychopathology in 862 men and 913 women adopted by non-relatives, was studied. Both male and female adoptees were at greater risk to develop alcohol abuse if their biological, but not their adoptive, parents were alcoholic. Three types of families with alcoholism were distinguished that differed in frequency of alcohol abuse, somatoform disorders in women and in relation to antisocial behaviour in male adoptees. The combination of both genetic and environmental risk factors was necessary for the development of alcoholism in the most common, milieu-limited type of alcoholism. In families with a less common, male-limited, type of vulnerability, alcohol abuse was highly heritable in men, but women had multiple somatic complaints and seldom abuse. In a third type of family the common vulnerability was expressed as antisocial behavior with violent criminality and recurrent alcohol abuse in males, but as high frequency somatization in female relatives.
