The Role Genetics Play in Alcoholism

The Role Genetics Play in Alcoholism

In other words, individuals are considered legally too drunk to drive if their BAC is 0.08 percent or higher. If you have a genetic risk of developing an alcohol addiction and have exhibited signs of this disorder, it’s important to seek treatment as soon as possible. Counseling and support can help tackle social and environmental factors that could contribute to an alcohol problem in the future. If you or a loved one has already developed a problem, there are outpatient and inpatient programs that can help. It is believed that some people are genetically predisposed to having higher levels of tolerance and preference for alcohol, which may make them more likely to become dependent on it.

It makes the inevitability of familial alcoholism seem guaranteed when studies have shown a wide range of outcomes, including some individuals who never develop any symptoms or risks at all. Similarly, while there is a genetic component to alcohol tolerance, there have been largely inconclusive results about an alcohol dependence gene being hereditary. While the answer is not cut-and-dry, those with alcoholic parents show an increased risk of alcohol use disorders and developing an addiction to alcohol. Family studies have consistently demonstrated that there is a substantial
genetic contribution to alcohol dependence.

Genetics Of Alcoholism

Instead, hundreds of genes inside your DNA can potentially amplify your risk of developing an alcohol use disorder. Experts are attempting to identify these genes, but it proves difficult. So, no one knows just how big a factor genetics plays in the development of alcoholism.

Is there an addiction gene?

Scientists will never find just a single genetic change that causes addiction. Like most other diseases, substance use disorder is a complex trait. It's influenced by variations in multiple genes, plus factors from the environment. Every person inherits a unique combination of gene variations.

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. The alcohol research
community has begun to form larger consortia for sober house meta-analyses and it is anticipated
that with the resulting increase in sample size the number of robust associations
will increase. A second approach that will likely benefit the alcohol research
community will be greater examination of pathways or gene sets. These approaches
have been quite fruitful for some studies and need to be employed in analyses of
alcohol-related traits and phenotypes.

Family History as Verification

No, you are not destined to become an alcoholic just because your parents were an alcoholic. Alcoholism is a progressive disease that worsens with the continued use of alcohol but is not present at all if an individual abstains completely from alcohol. The test was conducted on specially-bred rats, and those with less of the protein produced by the gene were increasingly anxious and showed a marked preference for alcohol. At Pinnacle we offer drug and alcohol rehab facilities in Arizona that improve peoples lives and make healing possible. We take a comforting approach to healing those who are struggling with addiction.

  • Heavy drinking is defined as eight or more drinks per week for women and 15 or more drinks per week for men.
  • Concerns about alcohol consumption should be addressed by a medical professional.
  • If you have these genes, you might be prone to keep drinking when others might stop.
  • Other research has revealed that the same variation in the same gene as occurs in Europeans also influences risk in people of Asian descent, but that data was not included in this study.
  • We take a comforting approach to healing those who are struggling with addiction.

Can children inherit genetic materials from their parents that increase their vulnerability to alcohol? Several notable studies have been conducted to answer this question. At Family First Intervention, we have worked hard to educate families on alcoholism and recovery from alcohol addiction. We have decades of experience in helping families take the difficult yet necessary first steps toward alcohol recovery.
