Confused With Gene Test Results

I got my HLA DQ2 and DQ8 tests and I'm not sure what they mean. I do have an appt. with my GI doc. next week but I thought I'd ask here first.

Even though DQ2 and DQ8 were requested, the tests listed say HLA-DQB1 02 (DQ2)

HLA-DQB1 05 (DQ5)

Both have a * after them which indicates 'out of range'. There is no range given.

What is that ? I've waited 3 weeks for this?

I'm guessing I don't have either gene so it didn't register on their test??

Anyone else get results like this? These tests were blood tests pulled at a local lab and run by Quest Diagnostics in VA.

It appears as though you have the DQ2 (a celiac gene) and DQ5 (a/k/a DQ1, subtype 5.) The DQ1 is not one of the main genes predisposing to celiac disease, but many here have it (or have 2.) Enterolab calls DQ1 a "gluten sensitivity" gene. There is no "range" for gene results. They just tell you which 2 copies you have, as above.

I found this in Dr Green's book.

HLA-DQ2 is encoded by alleles DQA1*05 and DQB*02.

DQ8 is encoded by alleles DQB1*0302 and DQA1*03.

I hope this helps.

Are you saying these were the results or the tests requested?

Those were the results. I've done a bunch of reading and I guess I have the DQ2 and DQ5. I know the DQ2 is for Celiac and I'm not sure what the DQ5 is about. Don't you have to have BOTH DQ2 and DQ8 to be celiac disease? It's all so confusing :(

And by the way, my total IgA was normal......

No, you only need one and there are a small percentage that don't even need one. DQ2 is the more common one and just because you have it, doesn't mean that you have (or will get) Celiac Disease. It means you are genetically at risk - but so is about 39% of the population (based on my son's gene test).

      Guinness, can you drink it?

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease. While it's fascinating to hear anecdotes from other coeliacs who can drink it without immediate issues, this is a risky exception rather than the rule. The core issue is that Guinness is brewed from barley...

      Gluten Issues and Vitamin D

      Interestingly, this thought occurred to me last night. I did find that there are studies investigating whether vitamin D deficiency can actually trigger celiac disease. Source: National Institutes of Health https://pmc.ncbi.nlm.nih.gov/articles/PMC7231074/

      Guinness, can you drink it?

      Before being diagnosed coeliac I used to love Guinness. Being made from barley it should be something a coeliac shouldn’t drink. But taking to another coeliac and they can drink it with no ill effects and have heard of others who can drink it too. is this everyone’s experience? Can I drink it? I get dermatitis herpetiformis and don’t get instant react...

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      Guinness, can you drink it?

      By Scott Adams · Posted

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease. While it's fascinating to hear anecdotes from other coeliacs who can drink it without immediate issues, this is a risky exception rather than the rule. The core issue is that Guinness is brewed from barley, which contains gluten, and the standard brewing process does not remove the gluten protein to a level safe for coeliacs (below 20ppm). For someone like you who experiences dermatitis herpetiformis, the reaction is particularly significant. DH is triggered by gluten ingestion, even without immediate gastrointestinal symptoms. So, while you may not feel an instant stomach upset, drinking a gluten-containing beer like Guinness could very well provoke a flare-up of your skin condition days later. It would be a gamble with a potentially uncomfortable and long-lasting consequence. Fortunately, there are excellent, certified gluten-free stouts available now that can provide a safe and satisfying alternative without the risk.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
