This is because people with acetaldehyde buildup are more likely to have troublesome reactions. There are also countless environmental factors (work, stress, relationships) that may lead to alcoholism. There isn’t one single “alcohol use disorder gene.” Rather, there are many different genes that Genetics of Alcoholism may influence whether someone develops an alcohol use disorder. Many people with alcohol use disorder hesitate to get treatment because they don’t recognize that they have a problem. An intervention from loved ones can help some people recognize and accept that they need professional help.
Analyses of RNA expression in lymphoblastoid cell lines suggested that SNPs
within this region on chromosome 5 had cis-acting regulatory
effects on the expression of HTR1A or
IPO11. Several of the candidate risk genes for alcohol dependence identified in these studies contribute https://ecosoberhouse.com/article/psychological-dependence-on-alcohol-physiological-addiction-symptoms/ to alcohol-related behaviors in animal models. Orthologs of PKNOX2, SEMA5A,
USH2A, DSCAML1, NR4A2, DDC, SGOL1, DTWD2 and NDST4 show differential expression in brains from alcohol-drinking mice compared to controls; (Mulligan et al. 2006, 2011; Wolstenholme et al. 2011).

A genetic predisposition or genetic susceptibility refers to an increased likelihood that you’ll develop a disease based on your genetic makeup. This information helps explain why drinking problems tend to run in families and why rates of alcohol abuse have historically been higher or lower in certain populations. Take our free, 5-minute alcohol abuse self-assessment below if you think you or someone you love might be struggling with substance abuse. The evaluation consists of 11 yes or no questions that are intended to be used as an informational tool to assess the severity and probability of a substance use disorder. The test is free, confidential, and no personal information is needed to receive the result.
- In addition, the postsynaptic density protein Homer plays a role in regulation of synaptic plasticity and neuronal development (Foa and Gasperini 2009) and alcohol sensitivity, in both flies and mammals (Urizar et al. 2007; Cozzoli et al. 2009).
- If you feel that you sometimes drink too much alcohol, or your drinking is causing problems, or if your family is concerned about your drinking, talk with your health care provider.
- If you are living with alcohol use disorder, know that you are not alone and that there are treatment options.
- Additionally, about 1.7% of adolescents ages 12 to 17 were reported as having alcohol use disorder in 2019.
Consider talking with someone who has had a problem with drinking but has stopped. Just as risk factors increase your chance of experiencing a condition, protective factors lower your risk. Some protective factors, such as natural optimism, may remain fixed over time. Other factors, such as friend groups and level of financial security, may be subject to change.
Is Alcohol Genetic – Am I Doomed?
In fact, some studies found that approximately 45% to 65% of risks related to alcoholism may be caused by genetic factors. These studies show that children with a family history of alcohol addiction are twice as likely as the general population to suffer from alcohol-related issues. Furthermore, flies exposed to ethanol undergo physiological and behavioral changes that resemble human alcohol intoxication.
This isn’t to say that people who have experienced the above will definitely develop alcohol use disorder. These factors may just make some people more likely to develop the condition. The world around you also can play a significant role in opening a door that leads to problematic substance use, notes Dr. Anand. About half of your susceptibility to developing a substance use disorder (SUD) can be hereditary.
