How are mthfr mutations and chiari malformation related? should i get tested if i have chiari? (and high b6 levels, for no good reason)

Forgive my frankness: One lab is promoting testing for mthfr mutations despite the fact that they merely identify folks who may be at slightly extra risk for this-and-that and who need to be extra-sure they get enough nutrients. A majority of people carry at least one 'mutant mghfr' and this is generating all kinds of scares. No relatioship to your chiari.
