If you are homozygous then you would have two copies of the gene mutation
Regardless, treatment would be the same, you just might not need as high of a supplementation.
I need to hone in on this post, I've not been this board in a long time, but came to see this post, but saw your reply and need to say that treatment is not the same. Very misleading.
Treating the different snp's, mutations, enzymes and pt's symptoms will all very much result in different treatments.
I've very knowledgeable about
MTHFR since I've done most of Dr Lynch's seminars and I am also April's LLNP (Lyme Naturopath).
My suggested for EVERYONE with Lyme is; get tested for MTHFR if you're not healing and find a good practitioner to help out and also, do Dr Lynch's seminar. The info is invaluable.
