The MTHFR gene is connected with the metabolism of B-vitamins. There are two known mutations of this gene. It is known that people who receive mutated genes from both parents have specific problems. What happens to people who receive a single bad gene (I.e. they are carriers of the gene) isn't as clear cut, but there are indications that having a single bad gene can be a problem
in some cases. From what I can make out, a single bad gene may or may not interact with other genetic and environmental factors to be an issue.
So -
my sister has had intractable migraine for 50 years. I told her about this gene, and that one of my kids is a carrier. The gene has a link to migraine, and migraine runs through my father's family like the red hair we all have.
So -
my sister started taking Vitamin B supplements- nothing outlandish, just the OTC supplement. Her headaches are much better.
Could be a coincidence, could be a connection. :shrug: This is a single anecdote, not peer reviewed research! It's something to talk with your doctor about.

Just about everything that can be connected to this gene can also be caused by other factors. There are people out there who will gladly take your money to tell you anything you want to hear about this gene. I'm already seeing sites featuring MTHFR gurus which weren't there a few months ago when I first looked into this.
