Can't thank you enough. I've placed the Amazon order and will do all you suggested.

This variant showed up in the whole exome test I took and was right at the top of the variant list. 23andme also tested and shows the SNP, but it's a crapshoot what variants they put in reports (when they were allowed).

Children aren't an issue as neither of my sisters nor I have been fruitful and multiplied. My one sister who also took the 23andme test has the variant as well.

The biochemistry is just baffling to me, so I appreciate your take on it.

Will report back after I've been on the regimen a bit. So glad you're feeling better!
