<<Disclaimer: Verify this information before applying it to your situation.>> In a recent summary posting there was a reference to "one person recommended Promethius labs for this as "they are the only one that looks for the third gene which to date has been positive in all biopsy-diagnosed Celiacs who tested negative on the two more common genes," I may very well be in that category, I do not have either HLA DQ 2 or 8 but am definitely gluten intolerant. Will the person who wrote this, or anyone else who has information, please e-mail me what this third gene is. Many thanks Pat * Send administrative questions to [log in to unmask] *
