Some people are more sensitive to stress, making it harder to cope with an unhealthy relationship or a fast-paced job. Some people experience a traumatizing event and turn to alcohol to self-medicate. Even though genetics influence such things, it remains unknown which variants are to blame as well as how they contribute. While genes definitely point toward a greater likelihood toward abuse, there is no gene solely responsible for alcoholism.

Genes Contributing To The Risk Of Alcohol Dependence

Environmental factors such as relationships, stress, and work can drive you to abuse alcohol. Your behavioral genes interact with your environment to form how you make decisions. You might be sensitive to stress, which makes it difficult for you to cope with a fast-paced job.

Lack of awareness can increase the chances of alcoholism developing. In the survey, the children who did not know of their higher risk drank three times as much and seven times as often as those who knew they might not develop alcoholism. Those who were not aware of the link were more likely to drink to intoxication than those who knew their risk. Factors like environment and your ability to handle stress and situations that may trigger dependency are also important. It is likely that, as with most complex diseases, alcohol dependence is due to variations in hundreds of genes, interacting with different social environments.

Get Alcohol Detox To Stop Drinking

Research has shown a close link between alcoholism and biological factors, particularly genetics and physiology. While some individuals can limit the amount of alcohol they consume, others feel a strong impulse to keep going. For some, alcohol gives off feelings of pleasure, encouraging the brain to repeat the behavior. Repetitive behavior like this can make you more vulnerable to developing alcoholism. A 2018 study also showed that genetic factors account for 40 to 60 percent of the reason people develop AUD.14 Since that study, specific genes were identified that link with the development of the disorder. Individuals can develop an alcohol use disorder even if they are not genetically disposed to do so. A person’s environment can strongly influence the development of an alcohol use disorder.

Study Reveals Genes Associated With Heavy Drinking And Alcoholism

AUD is a complex genetic disease, and research shows that many genes can affect a person’s risk. Mutations of the GABRB1 gene can increase the risk of AUD, while the ADH1B and ALDH2 genes protect against it. People who have inherited a likelihood of developing coronary artery disease alcoholism genetic statistics can take precautions. Likewise, those at risk of developing alcoholism can learn to recognize the potential problems and modify their behavior accordingly. Genes that affect alcohol consumption may increase the overall risk by increasing drinking, or reduce risk by reducing drinking.

  • For studies of rare variants, families are quite valuable for sorting out true positives from the background of individual variations that we all harbor.
  • If their body reacts poorly to moderate amounts of alcohol, they are less likely to develop AUD.
  • The gene is the main physical unit that passes inheritance from a parent to their child.

There was at least one chronic alcoholic parent in each family. From birth, each subject presented predetermined beta-endorphin levels. However, children of this population group aged between 6 months and 10 years old, registered lower beta-endorphin levels than other children of the same age. «These levels were even lower in children whose both parents were alcohol abusers», the researcher states. Children of people with AUD have a significantly higher risk of developing the disorder themselves. However, not everyone with alcoholic parents develops AUD.

Genetics And Alcohol Tolerance

Less than half of the children of people with an alcohol use disorder will develop an alcohol use disorder. However, having a genetic predisposition for alcohol addiction does not automatically mean someone will go on to have this condition. There are a number of preventative things that can be done to reduce the risk of alcohol abuse and addiction. At Healing Springs Ranch in Tioga, Texas, skilled trauma therapists are ready to help you or the person you love to gain freedom from alcohol addiction.

One of the most significant genetic factors in determining someone’s risk of developing AUD is tolerance. ADH1B — This gene causes someone to feel hot and sweaty, develop a face and body flush, and increase feelings of sickness when they consume alcohol. This gene affects the liver’s ability to metabolize alcohol.

Certainly, genetics are passed down through families, but family history also includes the environment in which one was raised. Childhood abuse, parental struggles, and mental illness in close family members all contribute to the risk of developing an addiction to drugs or alcohol. Also, behavioral genes influence your tendency for destructive behavior. Mental illness is also common in people with alcohol use disorder because they use alcohol to cope. If your family has a history of mental health issues, then those genes further increase your risk for alcoholism. Scientists are still trying to determine exactly how the genetics of alcoholism work.

Can Our Genes Affect Alcohol Treatment?

When the person drinks alcohol, for example, they may feel relaxed and happy compared to the stress they feel when they are sober. This reinforces the desire to use alcohol as a coping mechanism for stress. Those who have mental illnesses, especially anxiety, depression, bipolar disorder, and schizophrenia are very likely to struggle with co-occurring alcohol use disorder. Women are at risk of developing AUD faster than men due to differences in body mass, hormones, and metabolism. Variations in genes that affect the metabolism of alcohol in the body have been studied as factors that can increase or decrease the risk of alcohol use disorder.

Parent alcoholism impacts the severity and timing of children’s externalizing symptoms. Beta-Klotho — Those who have this gene can control their drinking. Someone without this gene is less likely to control their urge to keep drinking alcohol. To learn more about whether alcoholism is genetic, contact a treatment specialist today. Let’s look at the connection between alcoholism and genetics. There is a growing body of scientific evidence that alcoholism has a genetic component. Verywell Mind articles are reviewed by board-certified physicians and mental healthcare professionals.

The debate between nature versus nature in the development of diseases like alcoholism rages on. Specific genes are being mapped today to try and pinpoint the “addiction gene,” and whether or not there is one gene that will prove to be connected to all people struggling with alcoholism. It believed that genetic, environmental, social, and behavioral factors all contribute to the onset of addiction and alcoholism. Frequent exposure to alcohol and other substances can increase the risk of addiction. In particular, early exposure can heighten the risk of gaining a physical dependency on alcohol, especially in a familial setting. However, scientists also argue that genetics play a significant role in the risk of developing alcoholism and the likelihood of hereditary effects. Being born to a mother who drank during pregnancy or having other alcoholic family members increases your risk of alcoholism.

Is There An Alcoholic Gene?

Scores from the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) screenings and AUD diagnoses were obtained from the same population to conduct the GWAS for the two traits. The researchers also analyzed other data from health records to look for correlations between genes and diseases, as well as other non-alcohol related traits. Chronic heavy alcohol use can also cause long-term problems affecting many organs and systems of the body. Long-term overuse of alcohol also increases the risk of certain cancers, including cancers of the mouth, throat, esophagus, liver, and breast. Alcohol use in pregnant women can cause birth defects and fetal alcohol syndrome, which can lead to lifelong physical and behavioral problems in the affected child. Alcohol use disorder is a broad diagnosis that encompasses several commonly used terms describing problems with drinking.

If you produce fewer endorphins naturally, it can make it harder for you to feel happy without alcohol and, therefore, increases the desire to drink bigger quantities more often. This compounds the risk of problematic drinking, alcohol dependence, and addiction. A lack of naturally occurring endorphins is hereditary and can contribute to alcoholism. A person is then less likely to resort to patterns of regular and problematic drinking. In this way, ADH1B and ALDH2 are hereditary factors that actually reduce the risk of developing alcoholism.

Similar to environmental factors, your genetic disposition is considered to be another contributing factor that makes you more or less prone to addiction than other people. If you answered ‘yes’ to any of these questions, it’s likely you may have a higher risk of developing alcoholism. If you are not currently drinking, make sure you are cautious if you want to start socially drinking. You may want to avoid drinking altogether to avoid the risk. It’s important to understand that alcoholism is a disease and not a choice. Even with genetic markers, treatment can help you find sobriety. These are only 3 out of hundreds of different genes that impact the development of alcoholism.
