Separate heritability of alcoholism and psychotic symptoms.
The authors identified 259 alcoholic probands and 507 first-degree relatives. Alcoholic relatives of probands with psychotic symptoms were significantly more likely to have psychotic symptoms than those related to probands without psychotic symptoms. This finding suggests separate genetic transmission.
