More recently, our longitudinal design has facilitated characterizations of remission and recovery in AUD (e.g., References 31, 32, 33). A detailed description of these findings is outlined in the accompanying review (2. Sample and Clinical Data). Are some people more predisposed to Alcohol Use Disorder alcoholism (clinically known as alcohol use disorder) due to their genes? This question has been a topic of interest and debate among researchers and individuals struggling with addiction.
Alcohol Misuse Is Influenced by Environmental and Genetic Factors
The genes with the clearest contribution to the risk for alcoholism andalcohol consumption are alcohol dehydrogenase 1B (ADH1B) andaldehyde dehydrogenase 2 (ALDH2; mitochondrial aldehydedehydrogenase), two genes central to the metabolism of alcohol (Figure 1)20. Alcohol is metabolized primarily in the liver, although thereis some metabolism in the upper GI tract and stomach. The first step in ethanolmetabolism is oxidation to acetaldehyde, catalyzed primarily by ADHs; there are 7closely related ADHs clustered on chromosome 4 (reviewed in20). The second step is metabolism of theacetaldehyde to acetate by ALDHs; again, there are many aldehyde dehydrogenases,among which ALDH2 has the largest impact on alcohol consumption20. Several transcription factors have been implicated in alcohol sensitivity and/or induction of tolerance in flies. The hangover gene encodes a transcription factor that contributes to the induction of alcohol tolerance 90.

- When you first start drinking alcohol, you may feel happy, confident, friendly, and euphoric after a few drinks.
- If there’s a history of alcoholism in the family, you have a higher risk of developing AUD.
- Recently, in a sample of criminal alcoholics, it has been shown that the effect of testosterone on aggression and alcoholism is contingent upon MAOA–LPR genotype 85.
- Since then, there have been significant advances in techniques available for mapping genes and as a result considerable changes in outlook have occurred.
- Our ability to develop iPSCs from individuals with different genetic loading is producing insights into properties of cells derived from persons with archival electrophysiological and behavioral phenotyping, and how the cells differentially respond to ethanol exposure.
What Percentage of Someone’s Genetic Background May Contribute to Alcohol Dependency?
- Alcoholism, or alcohol use disorder (AUD), is characterized by an inability to control alcohol consumption despite the negative impact it has on one’s life.
- Rather, in AUD, only about fifty percent of the risk appears to be attributed to our genes.
- This work was supported by grant AA (TFCM and RRHA) from the National Institutes of Health.
- We respect individual employees for their unique potential and hold ourselves accountable for helping them to achieve their goals.
- As mentioned earlier, individuals with a family history of alcoholism are at a higher risk of developing the condition themselves.
What this means for family members of alcoholics is that you are not necessarily going to misuse alcohol yourself. Factors like your environment and ability to handle situations triggering dependency are just as important as genetics. These are things that we can remain mindful of as we continue to develop an understanding of alcoholism on a personal basis. Whether alcoholism is genetic or triggered by other factors, treatment is essential for overcoming alcohol addiction. At 12 South Recovery, we offer a range of treatment options tailored to meet each client’s individual needs.
Are You at Risk of Becoming an Alcoholic?
Today, studies have demonstrated that genes could predispose a person to alcohol dependence. Research like this could help identify people who have a higher risk of misusing alcohol so it can be mitigated and treated appropriately. Other intermediate phenotypes predict diatheses that include alcoholism as well as other psychiatric diseases. Relevant phenotypes in this regard include electrophysiological, psychological, neuroendocrinological and, more recently, neuroimaging why is alcoholism genetic phenotypes.
Whole-genome association
Our clients come from all walks of life, demonstrating that addiction doesn’t discriminate based on social status, education, or background. Our experience shows that heavy binge drinking can accelerate the addiction process significantly. The brain adapts more quickly to large quantities of alcohol, leading to faster tolerance development and dependency.
