This gene-environment interaction, known as epigenetics, helps explain why people with similar genetic traits can have different outcomes. Factors like trauma, chronic stress, peer pressure, early alcohol exposure, or growing up with heavy-drinking parents can all raise heroin addiction the risk. However, there’s no “alcoholism gene,” nor does a family history of alcoholism mean you’ll have a problem with alcohol. Studies have shown that individuals with a family history of alcoholism are more likely to develop alcohol-use disorders themselves.
Health Costs of Alcohol Abuse
- She said their study opens numerous doors for future research, chasing down possible connections between the alcohol-protective alleles and conditions that have no apparent connection with alcohol consumption.
- If you have a family history of alcoholism or other forms of substance abuse, then you have a higher risk of developing a substance use disorder yourself.
- A person who tolerates higher amounts of alcohol has a higher risk of AUD over time.
- Knowing about genetic predispositions to AUD can help a person take preventive measures and make informed lifestyle choices.

Children of Alcoholics: Statistics on the Effects of Alcohol on Families
NIAAA’s “Core Resource,” although intended for health care professionals, has helpful information for the public as well. One NIAAA-supported study, the Collaborative Study on the Genetics of Alcoholism Project (COGA), explores how genes affect vulnerability to AUD, and has an easy-to-understand web resource about alcohol and genetics. These professionals can help individuals understand the implications of their genetic https://ecosoberhouse.com/ predisposition and develop strategies for managing their risk.
Understanding that there is no single “alcoholic gene” helps reduce stigma, reinforcing that AUD is a complex, treatable health condition and not a moral failing. This perspective encourages a more compassionate and scientifically informed approach to prevention and treatment. This complexity is why genetic testing is not currently used to predict who will develop AUD. Although commercial genetic tests can identify some variants in genes like ADH1B and ALDH2, this information provides an incomplete picture of a person’s overall risk.
Their collective expertise shines through in each article, offering readers valuable guidance, the latest in addiction science, and inspiring stories of healing and transformation. The Grove Editorial Team is committed to educating, supporting, and empowering individuals and families on their journey toward a healthier, substance-free life. Many people with alcohol use disorder hesitate to get treatment because they don’t recognize that they have a problem.
3. Identification of Copy Number Variations by Genetic Testing
The human genome consists of thousands of genes, and it is believed that multiple genes are involved in the genetic predisposition to alcoholism. These genes may influence various aspects of alcohol addiction, including the metabolism of alcohol, neurotransmitter levels, and reward pathways in the brain. While genes play a significant role in predisposing individuals to alcoholism, environmental factors also have a notable impact. The interplay between nature and nurture is often considered in the context of alcoholism, as it is clear that both genetic and environmental factors contribute to an individual’s susceptibility to the disease.
Over the past two decades, several genesunderlying susceptibility have been identified. Extensive study of the alcoholmetabolizing genes has demonstrated their important role in disease risk. Additionalgenes have been identified that have expanded our understanding of the genes andpathways involved; however, the number of findings to date is modest. First and perhaps foremost, most studies ofalcohol-related phenotypes have been small – hundreds or a few thousandsamples. Most robust associations that have been reported in common disease haveemployed tens of thousands of samples and are now beginning to combine severalstudies of these magnitude into even larger meta analyses.
A standard drink is defined in the US as 12ounces of beer, 5 ounces of wine or 1.5 ounces of spirits, all of which approximate14 g of pure ethanol). The GI tract is exposed to very high levels of alcohol as it passes throughthe mouth, esophagus, stomach and intestinal tract, and most ethanol passes throughthe liver before entering the circulation. Alcohol levels in common drinks rangefrom approximately 5% (1.1 M) for beer, 11-15% for wine (∼3M) and 40% for spirits (∼9 M).
