Is There an Inherited Family Alcohol Gene?

It’s also not guaranteed, as about half of the risk is due to factors aside from genetics. High levels of stress in the environment, a lack of family support and engagement, and peer pressure can make a person more susceptible to engaging in patterns of problematic drinking that can lead to alcoholism. One of the most common forms of research into the family link for alcoholism comes in the form of identical twin studies https://ecosoberhouse.com/ and study of the human genome, or genomic medicine.

• “These genes are for risk, not for destiny,” stressed Dr. Enoch Gordis, director of the National Institute on Alcohol Abuse and Alcoholism.
• According to the 2021 National Survey on Drug Use and Health, AUD affects approximately 29.5 million people in the United States.
• If you have multiple relatives with alcohol addictions or other substance use disorders, you may have inherited the genes that put you at risk.
• Children of parents with AUD are about four times as likely to develop drinking problems than the general population.

This may reflect boththe limited sample sizes and is alcoholism inherited the clinical and genetic heterogeneity of thedisease. As noted above, the functional ADH1B polymorphism isnot represented on GWAS platforms; GABA-receptor genes are often nominallysignificant but well below genome-wide significance in these studies. Thus, thegenes and SNPs found through GWAS have had little overlap with previous findingsbased on candidate genes/pathways and linkage analyses. Alcohol is widely consumed, but excessive use creates serious physical,psychological and social problems and contributes to many diseases.

What Environmental Factors Affect Alcoholism?

If you are living with alcohol use disorder, know that you are not alone and that there are treatment options. Because of this, people with the genes ADH1B and ALDH2 might be less likely to develop the condition than those without it. If exposed to alcohol at a young age, you’re more likely to develop AUD, especially if you start drinking at 15 or younger. Your genetics don’t only increase your risk of AUD — they may have protective elements as well. Researchers at the University of California at San Francisco (UCSF) are using fruit flies to find the genetic causes of alcoholism. According to scientists, drunken drosophila fruit flies behave the same way humans do when they are drunk.

Can alcohol use disorder be genetic?

Your socioeconomic status is made up of economic and societal factors such as your income, level of education, employment, location of residence, and available resources. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition, text revision (DSM-5-TR), a clinical diagnostic guidebook, indicates that AUD often runs in families at a rate of 3–4 times higher compared with the general population. According to the 2021 National Survey on Drug Use and Health, AUD affects approximately 29.5 million people in the United States. More than 800,000 of the people affected are children between the ages of 12 and 17 years.

Are You at Risk of Becoming an Alcoholic?

In a recent study, HOTAIR induction in immune cells was required for the pro-inflammatory response 44. Upregulated HOTAIR expression is involved in CNS disorder pathogenesis by sponging miRNA, inducing apoptosis, activating microglia and neuroinflammation, and inhibiting BDNF transcription 43. These findings reinforce evidence that neuroinflammation plays a crucial role in the development and persistence of SUDs. While alcoholism itself is a legitimate medical condition referred to by clinicians as an alcohol use disorder, it’s important to note that taking the first drink is a choice, particularly when alcoholism runs in the family. When someone decides to drink for the first time, particularly if alcoholism runs in their family, they are putting themselves at risk of becoming addicted.

For example, a review of 12 different adoption and twin studies found that genetics explain roughly 50% of alcohol use disorder developments, showing a strong link between alcoholism and genetics. Mixing alcohol with other drugs can also compound the risk of developing alcohol dependence. Drinking in moderation and limiting your alcohol consumption can help to decrease the odds of developing alcohol dependence and also for alcoholism. As with most aspects of a person’s life, one’s propensity toward alcoholism is governed by a complex interplay of nature and nurture. While neither genes nor environment alone can predict alcoholism, both interact in complex ways to increase or decrease a person’s risk. What this indicates is that your family history can heavily influence your propensity for alcoholism.

The role of a person’s environment in AUD shows differences when comparing people with parents addicted to alcohol versus other family members. Growing up around people with an alcohol addiction makes someone more vulnerable to developing AUD, but not all children of alcoholic parents develop AUD. This could be because not everyone inherits their parent’s genes linked to AUD. Environmental factors, such as upbringing, can also increase the risk of AUD.
