Hi Sylvia

Which mutation does he have two of? C677t or the other one A???

My son also positive for one mutation of the C677t.

The C677t is the bodies ability to convert and use Folic Acid and the B12. If he cant convert it, they are not used, and can be toxic sitting in the body, additionally, hes not getting any of those necessary nutrients. His labwork will show HIGH B12 levels but specialists know what other labs to look at (counter with low of something else on the lab work-I cant recall the name at the moment)

Keep in mind, and look up low B12. It can cause Depression. Folic acid has its issues also.

I know of TWO FANTASTIC doctors who are well skilled with this:
Dr Melanie Alarcio, Pediatric Neurologist, in Arizona and Dr David Berger, Pediatrician, Wholestic Pediatrics in Tampa Florida. Both of these doctors states, "Lets clean up the labs and see what we have left". I LOVE that approach, no band aids, no drugs to treat symptoms. They are both great at getting to the source and treating the source.

If he has a two copy mutation, you really need to follow up on this! For starters he will most likely be put on methylcobabullin (converted form of B12)injections and an MTHF supplement.

I hope this helps
