People with a family history of alcoholism are more likely to develop addiction themselves. This suggests that there is an inherited component to alcoholism, where certain genes that predispose individuals to addictive behaviors are passed down through generations. While it might be true that genetic factors contribute significantly to AUD risk, they do not determine your fate.
Your Own Risk and How to Manage It
However, it is important to note that genetics alone do not determine whether an individual will become an alcoholic. Environmental factors, such as social influence and exposure to alcohol, also play a significant role. Genetic predisposition refers to the increased risk of developing a certain condition or disease based on an individual’s inherited genetic makeup. When it comes to alcoholism, certain genes have been identified that increase the susceptibility to developing an addiction.
- COGA is one of the few AUD genetics projects that includes a substantial number of participants of African ancestry.
- This means that about half of AUD risk can be attributed to genetic influences, while the remainder is shaped by environmental factors.
The ALDH Gene and Alcohol Metabolism
This metabolic switch channels excess metabolic energy into the synthesis of fatty acids and contributes to the development of fatty liver syndrome during excessive alcohol consumption. In addition to the behavioral similarities between invertebrate and mammalian models, invertebrates use similar neurotransmitter systems, neuropeptides, synaptic proteins, channels and signaling processes to mediate ethanol-induced behaviors 46. In vertebrates, neuropeptide Y (NPY) signaling plays a role in alcohol intake and dependence 61, 62.
Mental Health Treatment
While genetics can increase susceptibility, exposure to certain environmental triggers, such as stressful life events or peer pressure, can further contribute to the development of alcohol abuse. Additionally, comorbid mental health disorders, such as depression or anxiety, can interact with genetic factors to increase vulnerability to alcohol abuse. One key aspect of the genetic component of alcoholism is the heritability of the disease. Studies have shown that alcoholism tends to run in families, indicating a strong genetic influence. This suggests that certain genes or combinations of genes contribute to a person’s vulnerability to alcohol addiction.
Blood tests on subjects displaying this effect showed increased levels of acetaldehyde, a breakdown product of Drug rehabilitation alcohol, which resulted in an uncomfortable sensation of warmth in the skin, palpitations and weakness. By the 1980s investigators traced the reaction to an enzyme involved in alcohol metabolism, aldehyde dehydrogenase, and eventually to the gene that encodes it, ALDH1. The enzyme breaks down acetaldehyde, but slight variations in the gene’s DNA code in these subjects caused the enzyme to work more slowly. When these individuals ingested alcohol, the acetaldehyde–which may be toxic in high doses–was building up in their bodies. “The study of only one group of genetically similar individuals (for example, individuals of shared European ancestry) could worsen health disparities by aiding discoveries that will disproportionately benefit only that population.” The researchers analyzed genetic data from the 3 million 23andMe research participants, focusing on three specific little snippets of DNA known as single-nucleotide polymorphisms, or SNPs.
- By integrating holistic therapies, individuals can receive a comprehensive treatment plan that addresses all aspects of their well-being, leading to a higher chance of sustained recovery.
- NADPH is a necessary cofactor for the biosynthesis of fatty acids along with acetyl-CoA, generated by the metabolism of ethanol.

- By understanding the genetic basis of alcoholism, researchers can work towards developing more effective interventions and treatment options for individuals who are genetically predisposed to the disease.
Decide in advance how many days a week you’ll drink and how many drinks you’ll have on those days. Imagine your dad enjoys a glass of wine with dinner and maybe a beer during weekend barbecues. On the other hand, your mom has faced multiple stints in rehab and still struggles to maintain sobriety. The contrast between your parents shows how alcohol use can vary dramatically even between spouses. Where you live, who you is alcoholism a genetic disease hang out with, and what you believe can also affect how you use alcohol.
