There is a gluten genetic section in this book, and with the report that goes along with the gene: https://geneticdetoxification.com/book/
It covers many different genes. Gluten is only a small part of the book
I’m not sure if I had true Celiac disease, and the reports I’m running are showing I’m herterozygous for the common celiac disease genes. But I did have gluten intolerance for a while and I had dermatitis herpetiformis at that time too. It turned out I had a leaky gut and since I’ve fixed that I’ve observed no issues with any food sensitivities.
I have rs2187668, CC genotype and rs7454108, CT and I was tested for Celiac but tested negative for it. I had already gone gluten free for some time and I guess you have to have been eating gluten/wheat for a while before taking it.
