Separate heritability of alcoholism and psychotic symptoms
BL Cook and G Winokur
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.
