What is the MTR Gene?
You might have come across the term MTR gene and wondered what is MTR?
The MTR gene gives your body instructions to make a protein called methionine synthase. This protein plays a crucial role in processing vitamin B12 and supporting your body’s methylation cycle which affects everything from energy to brain health and even your DNA repair systems.
In short, the definition of MTR is:
A gene that helps convert vitamin B12 into a form your body can use, supporting important bodily functions like cell repair, brain function, and detox.
What Does the MTR Gene Do?
- The MTR gene helps make methionine synthase, an enzyme.
- This enzyme helps convert homocysteine into methionine, using vitamin B12.
- Methionine is important for making proteins, regulating mood, and keeping your liver and nervous system in check.
Without a properly working MTR gene, your body can’t use B12 effectively, even if you take supplements!
What is the MTR Gene Mutation?
Here’s what that might lead to:
- B12 doesn’t get used efficiently
- Homocysteine levels can rise (which is linked to heart problems)
- Energy issues or fatigue
- Brain fog or mood swings
- Poor detox or increased inflammation
Important: Not all MTR gene mutations cause serious problems. But they can increase your risk for certain health issues especially if combined with other genetic variants like MTHFR.
How Do You Know If You Have the MTR Gene Mutation?
At Agen Genomics, we test for MTR gene mutations through both our Comprehensive and Methylation Tests.
We recommend starting with the Comprehensive Lifestyle Test, which includes the MTR gene along with 91 others and 112 SNPs for a broader view of your genetic health.
If you’re mainly focused on methylation, the Methylation Test also covers MTR.
Both tests can help reveal important insights, such as:
- Whether you carry the MTR gene mutation
- How it may affect your methylation and B12 metabolism
- Personalized recommendations to support your body
It’s simple, saliva-based, and designed to give you insights that help you take control of your health.
Why Should You Care About the MTR Gene?
Knowing your MTR gene status can help you:
- Understand why you feel tired even with a healthy diet
- Learn why B12 supplements may not be helping
- Make smarter choices around nutrition, detox, and supplements
- Support your mental clarity and energy levels naturally
This isn’t just science, it’s about helping you feel better, long term.
MTR Gene and Other Genetic Partners
The MTR gene works closely with other genes like:
- MTHFR: Helps with folate metabolism
- TCN2: Transports B12 into cells
- MTRR: Helps “recharge” methionine synthase
Together, these genes form your methylation network, which helps your body manage toxins, brain function, and even how your genes are expressed.

What is the MTR gene in simple terms?
It’s a gene that helps your body use vitamin B12 to create energy, protect your brain, and support detox.
What does a mutation in the MTR gene mean?
It means your body might not be using B12 properly, which can affect your energy, heart, and mental health.
