OK Sorry I am not +/+ for both of those I am +/+ for 2 MTRR SNP's below is what Heartfixer has to say. I need read this carefully but it seems he suggests Hydroxy and Methyl B12
I would appreciate any explanations that may make his statement clearer to me. I have a hard time understanding this
stuff. My intuition tells me that I have been missing a piece of my puzzle and given that I have 2 of these seems like something I need to pay attention to.
MTRR: Methionine Synthase Reductase
A66G
+/- (A/G) +/+(A/A)
A substituted for G at site 66.
H595Y
+/- (H/Y) +/+(H/H)
H substituted for Y at site 595.
Function
Generates the Methyl-B12 used by MTR to convert 5-Methyl-THF into Methionine.
Findings
Homocysteine levels will likely be elevated.
Problem
Methyl-B12 cannot be generated to allow MTR to convert Homocysteine and 5-Methyl-THF into Methionine. Homocysteine toxicity will occur as well as impaired formation of S-Adenosyl Methionine (SAMe) such that methylation in general will be impaired
Treatment
1. Supplement with B12, Hydroxy-B12 if Methyl groups are in excess or Methyl-B12 if they are not, or a combination of the above.
2. Supplement the backdoor Homocysteine to Methionine pathway (via BHMT) with TMG (trimethylglycine), phosphatidylserine, or phosphatidylcholine. Avoid dimethylglycine (DMG) which would actually slow down the Homocysteine to Methionine conversion.
Monitoring
None except Homocysteine levels if elevated pre-treatment
Modifier
MTR – if abnormal will need even more B12, as this is an up regulation, increasing the demand for Methyl-B12 (see graphic below).
Modifier
COMT: if +/+ or +/- there will be delayed breakdown of Dopamine via Methylation so there will be extra Methyl groups available so we would tend to use Hydroxy rather than Methyl-B12
VDR Bsm/Taq: -/- is normal and allows for higher levels of dopamine and higher methyl group status, so here you would tend to use Hydorxy-B12, while +/+ VDR status leads to lower dopamine and Methyl status such that Methyl-B12 would be more appropriate than the hydroxyl-B12 form. So if you are (+) for COMT and (-) for VDR you will have high dopamine levels and lots of Methyl groups, while is you are COMT (-) and VDR (+) you will have low dopamine levels and lower levels of available Methyl groups so you would tend to use Methyl-B12 to help overcome the defect in MTRR.
