Is Addiction Hereditary?

If a person experiences any 2 to 3 symptoms, they will be diagnosed with mild alcohol use disorder. However, a crucial disclaimer is that these markers don’t guarantee one will become a heavy drinker. The National Institute on Drug Abuse highlights a potential overlap between genes related to alcoholism and opioid misuse. Notably, genes related to pain sensation collaborated with neural channel and excitation genes, vital for neuroscience communication. The study highlighted genes with silent mutations affecting alcohol use and emphasized the significance of studying gene groups over individual genes. Alcohol use disorder has become a prevalent problem that affects even the youth.

These factors make people resilient even though they are in a high-risk environment. The home environment, particularly during formative years, can significantly influence one’s relationship with alcohol. Children deprived of consistent parental guidance or those subjected to abusive households are at an increased risk of turning to alcohol, potentially leading to substance abuse later in life. Research shows that genetics and gene variations can increase alcoholism risk.

Genetics Of Alcoholism

Recent estimates indicate that 5.6% of individuals meet criteria for a past year AUD [2], resulting in significant social, economic and public health costs [3,4]. Some genes may contribute to an increased susceptibility to addictions
in general. Genetics of Alcoholism Importins are involved in transport of proteins and RNA
between nucleus and cytoplasm, and serotonin has been implicated in many neural
processes; HTR1A agonists reduce the anxiety-like behavior induced by repeated
ethanol withdrawals in rats79.

It’s difficult to determine the precise contribution of gene and environmental interactions in alcohol use disorders. However, the environment tends to have a stronger influence on the development of alcohol and drug abuse than genetics. If you have a family history of alcoholism or other forms of substance abuse, then you have a higher risk of developing a substance use disorder yourself. 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). Other mutants include slowpoke, which encodes a large-conductance calcium-activated potassium channel (Cowmeadow et al. 2005, 2006), and the transcription factors hangover (Scholz et al. 2005) and dLmo/Beadex.

Genetic Predisposition For AUD

There are many cases of AUDs running in families from one generation to the next, or ones that are potentially genetic but not hereditary.

Reciprocal drinking is common early in relationships, and it is often hard to discern if someone is not aware of the signs. However, as the relationship progresses and you get to know each other better, if you notice that the drinking behaviors are problematic and don’t say anything, your inaction is enabling the problem to continue. No, you are not destined to become an alcoholic just because your parents were an alcoholic.

For example, San Diego’s Renaissance Treatment Center has helped over 1,200 people overcome addiction and embrace a sober lifestyle. Even more prevalent than these factors is engaging in enabling and sympathetic drinking with a significant other who is abusing alcohol.

The genetics of alcohol dependence

An experiment using rats at Linköping University in Sweden discovered that those with reduced expression of the gene GAT-3 become addicted to alcohol. This brain chemical is widely thought to be involved in alcohol dependence. People with enzyme variants that allow for the fast buildup of acetaldehyde from alcohol (ethanol) are at less risk for addiction compared to those who metabolize alcohol efficiently to acetate.

  • In addition to affecting alcohol addiction risks, these genetic factors may lead to increased alcohol consumption and heighten the risk of alcohol-related diseases, including certain cancers.
  • Is alcoholism genetic is a question many families ask after seeing one or more family members spiral in addiction.
  • As it relates to alcoholism, genes, environment and social interaction can all affect a person’s risk level for alcohol addiction.
  • They have seen behaviors of adults who have had alcohol and may be desensitized to drinking because of their environment.
  • Acute effects are characterized by agitation and sedation, whereas long-term effects result in induction of tolerance and addiction.

According to a review from 2016, genes that promote alcohol metabolism and the production of enzymes, such as alcohol dehydrogenase and aldehyde dehydrogenase, can be protective against AUD. The more genetic factors you have, the higher your risk may be of having AUD. That doesn’t mean you’ll absolutely develop AUD if you have a family member living with the condition. You may have a higher genetic predisposition, but the underlying causes of AUD are multifaceted and complex. By the same measure, those who choose not to drink alcohol at all during their lives will not develop AUD, even if they are unknowingly at high risk, genetically speaking.
