In children with cerebral folate deficiency, the cerebrospinal fluid shows low levels of 5MTHF, and a loss of white matter in the brain (leukodystrophy) may occur. As a result of the decreased levels of 5MTHF, the child experiences low levels of Vitamin B folate. [ 12 ]
The resulting enzyme is thermolabile and in homozygotes, enzymatic activity is depressed to 35% of its usual level. [10] The second variant is a milder one, caused by a homologous 1298C polymorphism. This leads to 68% of the control values of enzyme activity, [10] and it normally does not lead to low serum folate. [9]
The MTHFR nucleotide at position 677 in the gene has two possibilities: C or T . C at position 677 (leading to an alanine at amino acid 222) is the reference allele. The 677T allele (leading to a valine substitution at amino acid 222) encodes a thermolabile alternative enzyme variant with reduced activity. Both reference and alternative ...
lutants.4 Moreover, children have little or no choice about where they live or go to school. Childhood is a critical period for brain forma-tion. Researchers have shown that children ex-posed to air pollution perform worse on cogni-tive functioning tests6 and have impaired neurological function7–9 and lower IQ scores10 compared with other ...
The Methionine Synthase Reductase (MTRR) gene primarily acts in the reductive regeneration of cob(I)alamin (vitamin B12). [10]Cob(I)alamin is a cofactor that maintains activation of the methionine synthase enzyme (MTR) Methionine synthase, linking folate and methionine metabolism.

MTHFR = methelynetetrahydrofolate reductase; MTHF = Methyltetrahydrofolate. Without the effective reductase action, your body can't make enough of the folate form. You also won't have an efficient methylization cycle to clean up all kinds of junk in your body. Work with your medical doctor to test for MTHFR defects and appropriate supplementation.
