Later, a larger study focusing on half-siblings from families of alcoholics and controls reported on 154 subjects, finding that adverse alcohol outcomes in offspring related more closely to alcoholism in a biological parent than alcohol problems in the parents of upbringing (Schuckit et al., 1972). This article was published at about the same time as several large adoption studies from the United States, Denmark, and Sweden, which confirmed the three-fold or higher increased risk for alcoholism in sons of alcoholics adopted away and raised by nonalcoholics, although less conclusive evidence was found for daughters of alcoholics (Goodwin et al., 1973, 1974, 1977). One investigation compared alcohol-related outcomes in sons of bepotastine alcoholics raised in their original families with outcomes for their brothers who had been adopted out, finding similar rates of alcohol problems in both brothers (Goodwin et al., 1974). Studies of twins were also useful in distinguishing between genetic and environmental influences in alcoholism. This approach takes advantage of the fact that although identical twins share 100% of their genes, fraternal twins share only 50% (the same as any full siblings). Because twin pairs are usually raised together in the same homes and experience the same childhood life events at the same ages, a higher level of similarity for a diagnosis among identical compared with fraternal twins indicates that genetic factors were likely to have contributed to the development of the disorder, not just childhood environment. Twin studies were carried out in the United States, Finland, Olaparib purchase Sweden, and the United Kingdom (Gurling et al., 1984; Hrubec and Omenn, 1981; Kaji, 1960; Kendler et al., 1994; Murray et al., 1983; Partanen et al., 1977), and almost all supported a genetic influence in alcoholism with an estimated proportion of the risk explained by genes of about 60% (Edenberg, Y-27632 cell line 2011; Kendler et al., 2012). Similar studies with similar results were seen for other drug-related problems (Bierut, 2011; Tsuang et al., 1996). Investigators next turned to methods for identifying specific genes that contribute to the risk for these conditions. An important step was to identify some genetically influenced characteristics, or phenotypes, through which the genes were likely to operate. One such intermediate phenotype was associated with a decreased risk for AUDs but was unrelated to SUDs: an intense skin flush after drinking related to several variations in alcohol metabolizing enzymes that were associated with an enhanced sensitivity to alcohol. This phenomenon had been observed for centuries in Asian drinkers (Japanese, Chinese, and Koreans), and the enzymes involved were identified in the 1970s (Bosron et al., 1980; von Wartburg, 1980). The second intermediate phenotype, one that related to an enhanced risk for both AUDs and SUDs, was the long-known association between substance-related problems and impulsive behaviors (Dick et al.
