What Is the MTHFR Gene and Should You Get Tested?
The MTHFR gene has become one of the most talked-about genetic markers in wellness and functional medicine. But what does it actually do—and should you
Cerebral folate deficiency (CFD) is a condition linked to autism spectrum disorders, affecting folate metabolism in the brain. Understanding this connection can help families take proactive steps toward supporting neurological health. At Methylation Test Canada, we provide advanced genetic insights to guide personalized interventions.
Many families begin by exploring how folate metabolism affects B12, folate, and choline levels to understand potential genetic contributors.
The “Autism Folate Trap” occurs when folate fails to enter the cerebrospinal fluid despite normal blood levels. This can lead to:
Understanding these pathways highlights the importance of genetic testing to guide personalized support.
DNA methylation and related genes influence folate processing and neurological function. Some key genes include:
| Gene | Function | Impact on Autism / Neurodevelopment |
| MTHFR | Folate conversion | Influences homocysteine and methylation |
| DHFR | Folic acid reduction | Supports methylation cofactor production |
| FOLR1 | Folate receptor transport | Critical for brain folate levels |
| COMT | Neurotransmitter breakdown | Modulates stress response and mood |
Proper interpretation of these genes through testing helps identify intervention strategies.
Methylation testing provides actionable insights for families and clinicians:
For those seeking broader health insights, advanced genetic testing can combine folate metabolism analysis with other metabolic pathways for a complete picture.
Families can use methylation insights to:
