If the gluten free diet helps you, I hope it works out like it did for me. I used to have 2-4 lung infections a year. Ex-doctor never thought twice about it. But I have them no more took me about a year to realize that the infections had gone missing!!! Frueden tag!!! Same with the sinus infections. My Pollen and mold allergies are much better, too. Was that really due to me maybe having DQB1*0301? I don't know yet.
Where does one find out the different risk associations with the different alleles? I'd like to know what else I can look forward to in the future! I have also had several scary lung infections in the last 10 years and suffered from recurrent tonsilitis as a child. I suppose I can blame my alleles for that too
Studying the biomedical factors of gluten sensitivity leads down many rabbit holes and time sinks. Dont stress over it. There may be a clearinghouse information of DQ and other alleles, but I dont know yet. I searched Celiac.com for "genetics" -- if there was any resource other than overviews of DQ2 and DQ8, I missed it. But this is new stuff [suggestion!]
If you know all you need to about your diet and run out of other things to do, you could search the internet for DQB1*0301 with whatever symptom or condition you are wondering about. Be prepared for reading technical papers. Thats how I study. I see that others some others do, too. I think gluten sensitivity and geekiness travel together.
I weeks ago I looked at what Wikipedia has now about HLA-DQ. There is a list of alleles and links articles on the related serotypes., e.g., DQ6 and DQ7.
I liked the discussion on Understanding DQ Haplotypes and DQ isoforms on the "DQ2" wiki page, explaining wide ranges of severity of sensitivity.
If you want to read more technical materials and fewer commercial sites, search the internet for gliadin instead of gluten. But this can take up a lot of time and may raise false or premature worries. The main thing I got out of all the reading is confirmation of how non-intestinal symptoms can associate with gluten instead of taking someones word to the contrary.
