While genetics do play a role in why alcoholism runs in families, it’s important to realize this isn’t the only reason, nor is it always the case. As was noted above, about 50 percent of the risk of becoming an alcoholic is genetic, but that means the other 50 percent has nothing to do with genetics. There are some underlying genetic issues that can lead to alcoholism or increase the likelihood of drinking becoming a problem, which is why people say alcoholism runs in families. While alcoholism itself isn’t considered a choice by most medical professionals, it’s important to note, particularly when alcoholism runs in the family, that taking the first drink is a choice. When someone decides to drink for the first time, particularly if alcoholism runs in their family, they are putting themselves at risk of becoming an alcoholic. The signs of an AUD might be clear as day to friends and family, but alcoholics can have a difficult time admitting there is a problem and continue their lives in denial.
Mental illness increases the likelihood of developing alcoholism by 20% to 50%. Our hereditary behaviors interact with our environment to form the basis of our decisions. 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. Healing Spring Ranch’s peaceful setting only an hour north of a Dallas alcohol rehab and northeast of DFW airport includes 50 acres of Texas quarter horse ranch land. Contributions to the literature regarding the role and function of TM6SF2 have been slow with the gene function remaining elusive.
Alcohol use disorder and problematic drinking are genetically correlated with substance use, certain psychiatric illnesses and other neuropsychiatric traits, according to a study involving Vanderbilt University Medical Center researchers. As I said, to learn more about this devastating disorder, we will need much larger studies and studies that include many more populations around the world. We are working toward assembling such studies and encouraging others to begin studying more populations. When we have discovered more genes that affect risk, the next step will be to study the mechanism through which they work, and that might lead to new treatments and better matching of individuals to a treatment more likely to work for them. The study was carried out by a working group of the Psychiatric Genomics Consortium Use Disorder, a worldwide collaboration among many groups and individuals. It is the largest study to date that looks at risk genes of alcohol dependence. Below, Edenberg describes more about their findings and what they’re studying next.
The expression of the top-scoring genes in IASPSAD in mouse brain correlates with handling-induced convulsions, anxiety-like behavior, and acute functional tolerance to ethanol, respectively. Several studies have integrated GWAS and gene expression or gene network data to cross-validate behavioral genetic findings . These pathways included histone methylation, neural signaling, and immune genetics of alcoholism pathways . Mamdani et al. reversed this type of analysis by testing for significant enrichment of previously identified GWAS signals in gene networks from their study. Additional approaches have taken human GWAS significant results for AD and provided additional confirmation by showing that expression levels for such genes showed correlations with ethanol behaviors in rodent models .
Family History Of Problem Drinking
The two enzymes that are responsible for alcohol metabolism are encoded by different genes, and which enzymes a person carries influences their risk for developing alcoholism. ADH metabolizes alcohol to acetaldehyde, which is a highly toxic substance and well-known carcinogen. Second, acetaldehyde is further metabolized into another, less active byproduct, Sober living houses which is known as acetate. Acetate is then broken down into water and carbon dioxide where it is eliminated from the body. Alcohol metabolism is controlled by a number of genetic factors, such as variations in the enzymes that break down alcohol; and environmental factors, such as the amount of alcohol an individual consumes and their overall nutrition.
The pace with which alcohol is converted to acetaldehyde is determined in part by differences in the alcohol dehydrogenase gene ADH1B. There are variations in ADH1B that speed up the conversion of alcohol to acetaldehyde, which can cause unpleasant reactions, such as nausea and flushing. That will generally reduce the chances that the person will drink heavily. Our study identified a strong protective effect of such variants on alcohol dependence. But despite being one of the strongest common genetic effects in psychiatry, these variants explain only a small portion of the overall genetic risk and a smaller proportion of overall risk. The results suggest many additional variants across the genome contribute to the risk of alcoholism, but their contributions are expected to be small, so very large sample sizes will be needed to identify them.

Their findings were unique, because they found the problem areas are located in genetic regulatory regions, not coding regions, as many researchers previously expected. This means that it is possible to carry the genes associated with addiction, and those genetic regulators can be switched “on” or “off”, depending on outside influences. For hundreds of years, people have suspected that alcoholism and other types of addiction may be heritable. In recent years, however, science has begun to show us – overwhelmingly, in fact – that if your parent has a drinking problem, there’s a good chance you may develop a problem with alcohol, too. Keep track of your daily basis, ask yourself – are my drinking habits safe or risky? It’s tricky to spot the difference between alcohol addiction and having a drink every once in awhile. ‘Harmful drinking’ happens when there is a pattern of drinking which can cause damage to your health.

These are things that we can remain mindful of as we continue to develop an understanding of alcoholism on a personal basis. According to the American Academy of Child & Adolescent Psychiatry, children of alcoholics are four times more likely than other children to become alcoholics.

If the disorder is serious, attempts to stop heavy drinking very suddenly may lead to serious complications, including withdrawal syndrome and seizures. Some individuals may need to reduce the drug in a hospital or rehabilitation setting to medically manage acute withdrawal. After detox, an individual may choose to attend either residential treatment facilities or outpatient treatment programs. Speaking with a medical physician is a good first step to genetics of alcoholism treat alcoholism. A physician may be able to tell you if you need assistance, work with you to put together an addiction treatment plan, possibly including medication, and/or refer you to a support group or counseling. E. Morton Jellinek, a pioneer in the study of alcohol abuse and dependence, suggested the “progressive phases of alcoholism” which came to be known as the Jellinek curve in 1950, which is still widely used today with modifications.
It should not be used in place of the advice of your physician or other qualified healthcare provider. Worsening symptoms can lead a person to drink even more, creating a vicious cycle. That’s why individuals struggling with substance use disorders and co-occurring mental health conditions require treatment for both conditions. The most effective treatment approach addresses addiction and co-occurring disorders simultaneously. Unfortunately, the strategy often worsens symptoms of alcoholism and co-occurring disorders. According to Mayo Clinic, drinking increases the likelihood of depression, mood swings, violence and suicide among people with bipolar disorder.
Alcoholism is frequently referred to as a family disease, and this is for many complex reasons. First, there is the overall impact living with an alcoholic can have on an entire family. “This suggests that somehow GABA reception might be involved in these behavioral effects,” Dick says.
The transition back to life outside of rehab is fraught with the potential for relapse. Aftercare resources such as 12-step groups, sober living homes and support for family and friends promote a life rich with rewarding relationships and meaning.

- There are also countless environmental factors that may lead to alcoholism.
- In contrast, the largest functional enrichment groups unique to Aliceblue were related to actin-based filaments and cardiac function .
- Although gene expression in brain tissue has been studied in AD humans , these studies are often difficult to conduct and interpret, due to lack of control over experimental variables and small sample sizes.
- While ADH1B and other genes can provide some limited insights into who might be at risk, whether or not someone develops alcoholism is the result of a complex network of genetic and environmental factors.
- Having a close relative, such as a parent or sibling, who struggles with alcohol use disorder increases the chances that a person will also struggle with the same addiction.
Entrepreneur Keir Weimer created a system called the Live Free Lifestyle to give purpose to his life after realizing he had a serious problem with alcohol. A tragic accident that claimed the life of Weimer’s friend and landed Weimer in prison for 3 and a half years was the beginning of Weimer’s motivation to live differently.

Overcoming Stigma As A Pathway To Recovery
In contrast, carriage of the wildtype allele promotes secretion of triglycerides and cholesterol into the circulation, protecting the liver at the expense of greater dyslipidaemia. This results in an increased risk of atherosclerosis and cardiovascular disease. Another unifying feature across these mega-modules, except Aliceblue, was significant functional enrichment for pathways that regulate gene expression. Specifically, these pathways were related to chromatin organization, RNA splicing, and translation- and transcription-related processes .
“But we don’t know exactly how, so we can’t tell what the pathway might be that leads from GABA receptor genes to alcoholism.” ADH and ALDH also determine if a person will get facial flushing when they consume alcohol. If there is too much acetaldehyde in the body as a result of an ALDH deficiency, a person will most likely have facial flushing. This is demonstrated in gene differences between European and East Asian populations. Up to 85% of East Asians have facial flushing, compared to up to 29% of Europeans. Other consequences of an ALDH deficiency include rapid heartbeat, headache, nausea and vomiting.
Genetics And Alcoholism
If a provider is unable to assist with a particular need they are committed to providing direction and assistance in finding appropriate care. When someone becomes dependent on alcohol, they can experience withdrawal symptoms when they’re unable to drink, such as anxiety, fatigue, nausea and vomiting, and headaches. No matter what addiction you are struggling with, there is a treatment program out there for you. If you’re struggling with drug addiction, help is out there from professional treatment providers. Benzodiazepines, or Benzos, are some of the most commonly prescribed medications in the world despite significant addiction risk. Verywell Mind uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
If a person takes disulfiram and then drinks, the result is flushing, nausea, and heart palpitations. This progression, continuing until the individual hits the bottom with excessive drinking and then moves back up to rehabilitation, is called the Jellinek curve. As the disease progresses, genetics of alcoholism an individual will usually need to consume larger quantities to get the desired effect. If alcohol is not available, the individual may go through withdrawal syndrome. Worldwide, the ratio of men to women who drink alcohol is 3.8, with 54% of men and 32% of women reporting being drinkers.
