I was just going to post the link Marlene posted.

I can't decide if it's surprising or not, but there's not a single doctor on that list from Maryland.

Ragtop, what is your FUT2 status? It affects the gut, B12 levels, etc...

If you don't know how to search for specific SNPs, use the search feature on the SNP ID (rsxxxxx), then just click on the results in the SNPs section.

FUT2 rs492602 G GG +/+ +/+
FUT2 rs601338 A AA +/+ +/+
FUT2 rs602662 A AA +/+ +/+

Or cheating, here are the links that will show your status. You just need to login.

I'm homozygous across the board...a non-secretor.
