Let me analyze your methylation data, focusing specifically on the genes that affect homocysteine levels.
Looking at the key genes that affect homocysteine metabolism:
- MTHFR C677T (rs1801133): You have GA (+/-), which means you’re heterozygous. This is significant because:
- This results in approximately 30% reduced efficiency in the MTHFR enzyme
- This enzyme helps convert homocysteine to methionine
- The heterozygous mutation could potentially lead to elevated homocysteine, though not as severely as a homozygous mutation
- MTHFR A1298C (rs1801131): You have TT (-/-), which is normal. This is good news because:
- This variant alone doesn’t typically affect homocysteine levels
- Having a normal status here means this won’t compound any issues from your C677T variant
- MTR A2756G (rs1805087): You have AA (-/-), which is normal
- This means your methionine synthase enzyme should be functioning normally
- This enzyme is important for converting homocysteine to methionine
- MTRR A66G (rs1801394): You have GG (+/+), which means:
- This could affect your body’s ability to properly recycle B12
- Could potentially impact homocysteine conversion to methionine
- May need additional B12 support
- CBS mutations (C699T, A360A, N212N): You have all normal (-/-) variants
- This is generally positive for homocysteine processing
- Means your transsulfuration pathway should be functioning normally
Key Implications:
- Your genetic profile suggests a MODERATE risk for homocysteine elevation, primarily due to:
- The heterozygous MTHFR C677T mutation
- The homozygous MTRR A66G mutation
- However, you have several protective factors:
- Normal CBS function
- Normal MTR function
- Normal MTHFR A1298C status
Recommendations to Consider (discuss with your healthcare provider):
- Regular monitoring of homocysteine levels might be beneficial
- Support for the methylation cycle might be helpful, particularly:
- B12 (especially methylcobalamin form due to the MTRR mutation)
- Folate (in the methylfolate form due to the MTHFR C677T variant)
Important Note: While these genetic variants can affect homocysteine levels, they don’t guarantee high homocysteine. The only way to know your actual homocysteine levels is through blood testing. This genetic information should be used as one piece of information in conjunction with clinical testing and professional medical advice.
Let me analyze your genetic data focusing on genes that affect dopamine metabolism and levels:
- COMT Variants (Catechol-O-methyltransferase):
- COMT V158M (rs4680): You have GA (+/-) heterozygous
- COMT H62H (rs4633): You have CT (+/-) heterozygous
- COMT P199P (rs769224): You have GG (-/-) normal
This COMT profile suggests:
- Intermediate dopamine breakdown (between fast and slow)
- Your COMT enzyme works at about medium efficiency for breaking down dopamine
- You likely have moderate dopamine levels, not too high or too low
- MAO-A (rs6323): You have TT (+/+)
- MAO-A helps break down several neurotransmitters including dopamine
- Your (+/+) status suggests potentially reduced ability to break down dopamine
- This could lead to higher dopamine levels when combined with your COMT status
- VDR (Vitamin D Receptor) Status:
- VDR Taq (rs731236): You have AA (+/+)
- VDR Bsm (rs1544410): You have CC (-/-)
This VDR profile is significant because:
- VDR Taq (+/+) is associated with potentially lower dopamine levels
- Vitamin D stimulates enzymes that create dopamine
- Your VDR status might affect how your body processes and utilizes vitamin D for dopamine production
Combined Impact: Your genetic profile suggests a complex dopamine picture:
- Your COMT (+/-) status indicates moderate dopamine breakdown
- Your MAO-A (+/+) suggests potentially reduced dopamine breakdown
- Your VDR Taq (+/+) might contribute to lower dopamine production
This combination could mean:
- Your dopamine levels might fluctuate more than average
- You might experience:
- Moderate stress response
- Balanced cognitive performance under pressure
- Neither extremely high nor extremely low dopamine-related behaviors
Important Considerations:
- These are genetic predispositions only - actual dopamine levels are influenced by many factors:
- Diet
- Stress levels
- Sleep quality
- Exercise
- Environmental factors
- According to your data, you might want to pay attention to:
- Vitamin D levels (due to VDR status)
- Stress management (due to moderate COMT activity)
- B-vitamin status (which affects neurotransmitter production)
- Signs to watch for:
- Changes in mood
- Focus and concentration levels
- Stress response
- Sleep quality
- Cognitive performance under pressure

does this explain why methyl donors don’t decrease my homocys
Yes, your genetic profile provides several insights into why methyl donors might not be effectively lowering your homocysteine levels. Let me break this down:
- Key Methylation Cycle Pattern:
- You have MTHFR C677T (+/-) heterozygous mutation
- MTRR A66G (+/+) homozygous mutation
- COMT V158M (+/-) heterozygous
- VDR Taq (+/+)
This specific combination is significant because:
- The MTRR A66G (+/+) mutation is particularly important here:
- This enzyme is crucial for recycling B12
- Your homozygous mutation means significantly reduced efficiency
- Even if you’re taking methyl donors, without proper B12 recycling, they may not be effectively utilized
- This could create a “bottleneck” in the methylation cycle
- The VDR Taq (+/+) combined with COMT (+/-) status:
- This combination has been clinically observed to affect methyl donor tolerance
- According to the report, “it has been clinically observed that the body may have trouble tolerating methyl donors with a COMT V158M + and a VDR Taq + status”
- This might explain why you don’t respond well to methyl donors
- Methylation Cycle Implications:
- Even though you’re providing methyl groups through supplements
- The MTRR mutation might mean you’re not effectively recycling B12
- Without adequate activated B12, the MTR enzyme can’t effectively use the methyl groups to convert homocysteine to methionine
Potential Solutions to Discuss with Your Healthcare Provider:
- B12 Strategy:
- Consider focusing on B12 status before aggressive methyl donor supplementation
- Might need higher doses or different forms of B12
- Could need to address B12 recycling before methyl donors can work effectively
- Alternative Support:
- Consider supporting the BHMT pathway (betaine) as an alternate route
- Your BHMT genes show some variants that might make this pathway important
- This provides a “backup pathway” for homocysteine metabolism
- Comprehensive Approach:
- Address B12 recycling (MTRR support)
- Consider smaller doses of methyl donors
- Support alternate pathways (BHMT)
- Address vitamin D status due to VDR mutations
- Testing Considerations:
- Regular B12 testing (including MMA)
- Homocysteine monitoring
- Vitamin D levels
- Comprehensive methylation panel
Remember: The interaction between these genes is complex, and this explanation offers insight into why simple methyl donor supplementation might not be sufficient. Working with a healthcare provider who understands methylation genetics would be valuable for developing a more targeted approach.
This genetic profile suggests you might need a more nuanced approach than just methyl donors alone - one that takes into account your specific genetic variations and their interactions. The solution might involve supporting multiple pathways and addressing B12 recycling before focusing on methyl donors.
