MTHFR is an enzyme crucial for converting folic acid into an active form known as L-methylfolate, which the body can utilize. L-methylfolate plays a significant role in synthesizing neurotransmitters like serotonin, dopamine, and norepinephrine, pivotal for mood regulation.
Certain individuals possess a mutation in the MTHFR gene, impairing their capacity to produce L-methylfolate. The TenDNA health report indicates whether an individual carries genetic variations in MTHFR. This information could be valuable to healthcare providers considering folate supplementation as a treatment approach for depression. The report assesses the presence of genetic variation in MTHFR through the evaluation of the C677T polymorphism. Possessing two copies of the MTHFR gene mutation might increase the likelihood of certain health conditions, although further research is warranted to confirm this correlation. You might be unaware of the mutation unless you undergo genetic testing or experience a health concern.

SNP polymorphisms related to the topic Vitamin B9 (folic acid):
| rs10604 | |
| rs162036 | Disorders of intracellular metabolism of cobalamin. Positive effect on the efficacy of folic acid therapy in patients with hyperhomocysteinaemia. |
| rs326124 | |
| rs543703 | |
| rs651933 | May mean that folic acid cannot be transported into cells, and may indicate a need for more folic acid |
| rs744731 | |
| rs942835 | |
| rs1031326 | |
| rs1051266 | The protein encoded by the gene transports folic acid into the cell and thus plays a role in the intracellular regulation of folate concentration. In this genotype, folate absorption is worse. Folic acid requirement is higher. Alcohol consumption is more critical for the risk of vitamin B9 deficiency. |
| rs1076991 | |
| rs1532268 | |
| rs1801131 | Reduces the formation of the active form of folic acid, which is necessary for the remethylation of homocysteine and other DNA molecules. Administration of the active form of folic acid (5-MTHF or L-methyltetrahydrofolate) can significantly improve risk scores for the effects of mutations. Also a factor that moderately increases the need for vitamin B2. |
| rs1801133 | A gene fragment known as MTHFR C677T, which encodes an enzyme involved in folic acid metabolism. A break in this gene fragment results in high levels of homocysteine, low levels of B12 and folic acid. If your tests show high homocysteine levels, your doctor will likely advise you on an appropriate diet and supplementation regime. Taking varieties of the active form of B9 methylfolate (5-MTHF or L-methyltetrahydrofolate), the active form of vitamin B12, methylcobalamin, is recommended to reduce your risks. |
| rs1801394 | Polymorphism can lead to elevated homocysteine levels independent of folic acid, vitamin B12 or B6 levels. It is a risk factor for neural tube defects and Down syndrome in the setting of higher homocysteine levels. |
| rs1805087 | Moderate risk factor for hyperhomocysteinaemia. A factor that increases the body's need for folic acid and vitamin B12. |
| rs1979277 | Polymorphism of enzymes that metabolise folic acid.It is required to obtain sufficient vitamin B6 for optimal gene activity. |
| rs2236225 | Possible increased risk of fetal birth defects. A 1.5-fold higher risk for Caucasian mothers to give birth to children with DNT (neural tube defect). The association in children with this mutation with an increased risk of heart defects is greater if their mother did not get enough folic acid during pregnancy. The risk is reduced with adequate levels of folic acid and vitamin B6. |
| rs2281617 | |
| rs2287780 | Polymorphism in folic acid pathway genes causing B12 deficiency and increased homocysteine. |
| rs2295639 | Gene responsible for folate pathway abnormalities, increases likelihood of late-onset Alzheimer's disease. |
| rs3828090 | |
| rs4973216 | The breakage results in impaired ability of the protein to transport folate and thiamine into cells, resulting in reduced absorption of vitamin B1 from food. Thiamine-reactive encephalopathy, characterised by seizures responding to high doses of thiamine, may develop. |
| rs6495446 | |
| rs6495449 | |
| rs7925545 | May mean that folic acid cannot be transported into cells, and may indicate a need for more folic acid |
| rs8004018 | |
| rs8011839 | |
| rs10064631 | Methionine synthase deficiency, impairing the metabolism of folic acid B9 and cobalamin B12. |
| rs10498514 | |
| rs10923895 | |
| rs11754661 | Genetic alteration of the folate pathway affecting genomic methylation content. |
| rs12512471 | Breakdown can cause tetrahydrobiopterin (BH4) deficiency. Treatment for tetrahydrobiopterin problems usually involves some combination of supplementation with L-DOPA, 5-HTP, B4 and folic acid. |
| rs17349743 | Gene responsible for folate pathway abnormalities, increases likelihood of late-onset Alzheimer's disease. |
| rs144637717 | Deficiency of cerebral transport of folic acid. |
