Dr. Genovese also said that repeated exposure to alcohol consumption and abuse could impact drinking behaviors later in life. Continued genetic research is needed to assist with eliminating the guesswork and help with the identification, prevention, and individualized treatment of substance use disorder.

Genetics of Alcoholism

First and perhaps foremost, most studies of alcohol-related phenotypes have been small – hundreds or a few thousand samples. Most robust associations that have been reported in common disease have employed tens of thousands of samples and are now beginning to combine several studies of these magnitude into even larger meta analyses.

There are also protective factors that reduce a person’s risk. Risk and protective factors are either environmental or biological. However, even those with a high genetic risk to substance abuse must first be driven by a nonhereditary factor to do it. The catalyst that leads to alcohol abuse is very often an environmental factor, such as work-related stress.

Alcohol is metabolized primarily in the liver, although there is some metabolism in the upper GI tract and stomach. The first step in ethanol metabolism is oxidation to acetaldehyde, catalyzed primarily by ADHs; there are 7 closely related ADHs clustered on chromosome 4 . The second step is metabolism of the acetaldehyde to acetate by ALDHs; again, there are many aldehyde dehydrogenases, among which ALDH2 has the largest impact on alcohol consumption20.

Studies suggests that triggers in your environment can alter the way your genes express themselves—effectively turning genes on or off. What’s even more interesting is that you may be Genetics of Alcoholism able to partially pass these changes on. Your life experience, and that of your family, may in some ways change your DNA.

Among identical female twins, there was a 30 percent likelihood.
