Dh Without Celiac Gene?

Does anyone who does not have a major celiac gene have confirmed DH? I have a friend who is gluten "sensitive" but does not have the classic celiac gene. He recently cheated and three days later woke up with bumps that look like little bug bites with a water blister at the head. (The genetic test looked only for the classic "celiac" genes and not any for those for gluten intolerance.) I'm just wondering if DH is even a possibility to consider.

DH usually shows up faster - my DH pops up within 30 minutes (which is handy, as I don't eat too much of the bad stuff!) I was told by my doctor that it is possible to have DH and not have the Celiac gene. I was diagnosed purely through the skin biopsy, nothing internal, and since I've been gluten-free for almost a year now, they don't want to go messing with my diet.

Also, DH is usually symmetrical - if it pops up on one elbow, it doesn't take long to pop up on the other. If it would make him feel better knowing for sure, he should make an appointment with a dermatologist and eat some wheat before he goes in to make sure he will be nice and rashy when he goes to see the doctor.

Yep. Me. I had it severely for many long miserable years. In my childhood I was told I had poison ivy 'in my blood stream' to explain why I would be covered summer and winter. After I went gluten free I would get the kind of breakouts you describe. At first they would appear in hours but after a couple of years gluten-free it now takes me about 3 to 4 days to get the one or two little blisters I now get. After folks have been gluten-free for a bit the antibodies leave the skin and the reaction can take longer to show up.

Me too-- I am DQ6 and DQ7. I have confirmed DH and it pops up within an hour, I would say, of getting glutened. I can pop up anywhere-- if it is on an arm, say, I can actually watch it form.

Since the research has a ways to go regarding genetic sequences, the answer must be yes.

(And of course, the above posts show same)

Just last month, a study was published saying they'd found 7 more genetic "areas of interest" for celiac disease.

It is also interesting to know that many people who are diagnosed as celiac (via biopsy or dietary response or bloodwork) do not get the genetic test done and do not know what their genes are. If more people who are sick got the test, I think the ideas about the DQ2 and DQ8 genes, as well as the reported percentages, would change drastically.

Maybe your friend can get a biopsy with next rash and therefore a diagnosis. I was told that DH is considered a definitive celiac diagnosis.

I just read at the www.thefooddoc.com site that some labs miss the celiac genes because they do not test the apha chains, thus missing the half DQ2 genes that some have there. He lists which labs do the whole test.

      Inflammation and Menier’s disease link?

      By trents · Posted

      How long have you been strictly gluten free? Certainly, it would be good to look into vitamin and mineral deficiencies and supplementation. The B vitamins, magnesium and D3 are all very important to neurological health. Unfortunately, it can be difficult to reverse gluten-induced neurological damage damage if it has gone on for a long time.

      Thanks Trents I'm strict with my gluten-free diet now. I just don't feel any better. I'm going to get tested for vitamins and minerals to see if I need some supplements. For sure I got some damage that doctors call Menier's and the only way they treat it is with medicine that does damage my body more than it helps.

      Hypothetical question about antibodies

      By Zuma888 · Posted

      Thank you Scott for your helpful response! Based on this, would you say someone who is on a gluten-free diet - but not strict about cross-contamination and occasional cheating - and tests negative for tTg-IgA while having normal total IgA is not likely to have celiac, even if they have been 'gluten-free' for years?

      Hypothetical question about antibodies

      By Scott Adams · Posted

      That’s a really insightful observation about antibody testing and the gluten challenge! You’re absolutely right that antibody levels can remain elevated for months or even years after going gluten-free, especially if there’s ongoing cross-contamination or occasional slip-ups. The immune system doesn’t reset overnight—it can take time for antibodies like tTG-IgA to normalize, which is why many doctors recommend waiting at least 6–12 months of strict gluten-free eating before retesting. For someone who’s been gluten-free for less than two years or hasn’t been meticulous about avoiding cross-contact, there’s absolutely a chance they’d still test positive, since even small amounts of gluten can keep antibodies elevated. This is partly why the gluten challenge (where you eat gluten before testing) exists—it’s designed to provoke a measurable immune response in people who’ve been gluten-free long enough for antibodies to drop. But you raise a great point: the challenge isn’t perfect, and false negatives can happen if the timing or amount of gluten isn’t sufficient to trigger a strong antibody response. This is why diagnosis often combines antibody tests with other tools like genetic testing or endoscopy. Your question highlights just how nuanced celiac testing can be! For people with celiac disease hidden gluten in their diets is the main cause of elevated Tissue Transglutaminase IgA Antibodies (tTG-IgA), but there are other conditions, including cow's milk/casein intolerance, that can also cause this, and here is an article about the other possible causes:

      Chest pain from celiac

      Thank you for your response! I have considered starting a food diary in the past, I suppose this is as good a time as any to start.
