Less intense response to alcohol sheds light on genetic tracing of alcohol dependence

mpact alcohol metabolism can cause a more intense response to this drug and a subsequent lower alcoholism risk.

Also, some families pass along a characteristic called impulsivity, which is influenced by genes as well as environment. "If a family carries a high risk of impulsivity and it is passed on to a child, that child is at high risk for alcoholism, drug dependence, gambling and violence," said Dr. Schuckit. He estimates that 20 percent of alcoholics carry their risk through the impulsivity characteristic.

Dr. Schuckit concluded, "The more we understand about the causes of alcohol dependence and the contributing genes, the more likely we will be able to identify tailored preventions and better evaluate treatments once alcoholism develops."
