Genetic Factors
Genetic factors play a significant role in alcoholism and may account for about half of the total risk for alcoholism. The role that genetics plays in alcoholism is complex, however, and it is likely that many different genes are involved. Recent research suggests that alcohol dependence, and other substance addictions, may be associated with genetic variations in 51 different chromosomal regions.
