Did you know that about 25% of people have a variation of the COMT gene, which influences how their bodies handle stress? This gene helps break down necessary brain chemicals, like dopamine and epinephrine, essential for mood regulation. 

When mutations like Val158Met happen, they can throw off the balance of essential brain chemicals, possibly leading to mood swings, anxiety, or even more severe conditions like schizophrenia or bipolar disorder. Many people don’t realize that their genetics could factor in these issues.

In this article, we’ll explore:

  • How COMT mutations affect brain chemicals
  • Common symptoms, like mood imbalances
  • Available testing options and treatment strategies
  • The impact of diet, supplements, and lifestyle on managing COMT mutations
  • The connection between COMT mutations and mental health

An Overview of the COMT Gene

The COMT gene makes a catechol-O-methyltransferase enzyme, which helps break down chemicals like dopamine, epinephrine, and norepinephrine. These chemicals are essential for controlling mood, supporting brain function, and allowing the body to handle stress.

Variants of the COMT gene can increase enzyme activity, reduce dopamine levels in the brain, and cause mood swings and cognitive difficulties.

What is the Role of COMT Enzyme?

The COMT gene produces an enzyme, catechol-O-methyltransferase, which helps break down brain chemicals like dopamine, epinephrine, and norepinephrine. These chemicals are vital in regulating mood, supporting brain function, and managing stress. Variations in the COMT gene can increase enzyme activity, reduce dopamine levels, and cause mood and cognitive difficulties.

Effects of COMT variations on health:

  • Genetic mutations in COMT can result in higher or lower dopamine levels.
  • It is associated with anxiety due to disrupted neurotransmitter regulation.
  • This leads to mood swings and cognitive impairments, affecting memory and focus.
  • Contributes to depression and other psychological issues. 

What is COMT Mutation?

A COMT mutation happens when there are changes in the genes, which can affect dopamine metabolism and brain functions. The most common mutation, Val158Met, changes one part of the gene, which can result in different enzyme activity levels:

  • Val/Val: High enzyme activity
  • Val/Met: Intermediate enzyme activity
  • Met/Met: Low enzyme activity

COMT Mutation Symptoms

COMT mutations can affect how the body processes toxins and dopamine, leading to mood swings, anxiety, and cognitive issues. In women, they may also contribute to hormonal imbalances, including estrogen-related problems.

Detoxification Problems

COMT mutations can reduce the enzyme’s ability to break down neurotransmitters and toxins, particularly affecting the liver and detoxification processes. 

Symptoms include:

  • Fatigue
  • Hormonal imbalances
  • Sensitivity to toxins
  • Difficulty processing medications
  • Digestive problems

Dopamine Imbalances

These mutations can cause dopamine imbalances, affecting mood, cognition, and emotional regulation. These variations are linked to mood-related conditions and can lead to behavioral changes and increased stress, making individuals more vulnerable to emotional and cognitive issues.

Symptoms of dopamine imbalance:

  • Mood swings and anxiety
  • Impaired memory and focus
  • Increased sensitivity to stress levels

Mutations in the MTRR gene, like COMT mutations, can also disrupt neurotransmitter metabolism, leading to similar health challenges. To understand how these genetic variations affect overall well-being, you can explore symptoms of MTRR gene mutation more.

Estrogen Imbalances

COMT mutations can affect the enzyme’s ability to break down estrogens, especially catechol estrogens, causing estrogen to build up and disrupt hormone balance. In women, this can lead to estrogen dominance, where having more estrogen than progesterone increases the risk of various health issues.

Potential health implications:

  • Increased risk of hormone-related cancers (e.g., breast cancer)
  • Menstrual irregularities and severe PMS
  • Mood swings and anxiety
  • Endometriosis and fibroids

COMT Mutation Test: How to Diagnose

COMT mutations can be identified through genetic tests, such as the DNA Methylation Genetic Test by TruMe Labs, which evaluates neurotransmitter and hormone metabolism. Other options include 23andMe, which can provide insights into COMT-related variations.

DNA Methylation Genetic Test by TruMe Labs

TruMe Labs uses genetic sequencing to assess DNA methylation for COMT mutations, examining key markers to determine how well the enzyme breaks down neurotransmitters and hormones. This test helps identify genetic conditions and provides insights into dopamine and estrogen metabolism management.

Test results can indicate:

  • Levels of COMT enzyme activity
  • Diagnosis of COMT-related genetic conditions
  • Impact on dopamine metabolism and emotional regulation
  • Risk of estrogen-related health issues​

COMT Mutation Treatment

Managing these mutations involves genetic counseling,  dietary adjustments, and supplements like B vitamins. Reducing stress and regular exercise help balance neurotransmitters.

Genetic Counseling and Testing

Genetic counseling helps individuals and families understand COMT mutations and advises on health impacts and management. Since a COMT mutation is a genetic condition, healthcare providers develop tailored treatment plans to address specific needs. Testing offers insights into neurotransmitter function and helps adjust treatment strategies for better healthcare outcomes. 

Benefits of genetic testing for families:

  • Finds genetic conditions related to COMT mutations
  • It helps families understand their potential health risks
  • Supports patients in making informed decisions about treatment and lifestyle

Dietary Adjustments

For COMT mutations, dietary changes help with management by supporting metabolic and neurotransmitter function.

Dietary recommendations:

  • Magnesium-rich foods (leafy greens, nuts)
  • B vitamins (B6, B12, folate)
  • Antioxidant-rich foods (berries)

Supplementation Like Vitamin B6 and B12 and Omega-3 Fatty Acids

For those with COMT variations, these supplements can support enzyme function: 

  • Vitamin B6: Helps balance neurotransmitters.
  • Vitamin B12: Supports energy and methylation.
  • Omega-3s: Boost brain health and reduce inflammation.
  • Magnesium: Aids in neurotransmitter processing.

These supplements are important in improving mood, lowering anxiety, and managing stress by helping the body process neurotransmitters more effectively. Researchers are also studying through clinical trials how these supplements can provide even more support for people with COMT mutations.

Lifestyle Modifications

To manage COMT mutations:

  • Practice stress-relief practices like mindfulness or yoga.
  • Exercise moderately to support mood and dopamine regulation.
  • Get consistent sleep to maintain emotional balance.
  • Avoid caffeine and alcohol.

These changes help balance neurotransmitters, improve mood, and reduce anxiety, promoting overall well-being. 

Foods to Avoid with COMT Mutation

People with COMT mutations should avoid foods that raise catecholamine levels, like those high in tyrosine or phenylalanine, as they can disrupt dopamine balance and lead to anxiety and mood swings.

High-catecholamine Foods

High-catecholamine foods worsen neurotransmitter imbalances, leading to increased anxiety and mood swings.
