I am double DQ2.  Yes, I consider myself super sensitive to gluten.  That is about all I know about it.

Do doctors usually test for this DQ2 gene or do you have to request it?  I am really sensitive to gluten.  If I eat a cookie I feel like I have the flu within 45 minutes.  If I have my girls tested for the DQ2 gene will that mean they will eventually have Celiac Disease too?

Yiu can request a gene test for HLA-DQ genes associated with celiac. If you have the gene there is a 50/50 chance that you kids have it too since they take one copy from each parent and each parent has two copies of HLA-DQ genes. If your kids test positive on the gene it doesnt mea they have celiac or thay they would definitely get celiac it just means that they are at a greater risk to get it than someone who doesnt have these genes especially if hey have double copies of celiac genes like my mom and aunt.

Which DQ2 genes do you have double DQ2.5 or DQ2.5 and DQ2.2 ?

Thanks PersianCeliac, does your mom and aunt have celiac?

Thanks PersianCeliac, does your mom and aunt have celiac?  

Yes both were diagnosed around 9 months ago. My aunt who is 47 years old is very very thin and never gains weight and had a problem with chronic diarrhea for 16 years ! And lots of gas build up and GI symptoms until this doc sent her for celiac panel. Her numbers were off the chart ! And her biopsy showed total atrophy. I read about the disease and found it its genetic so decided to test my mom. My mom had no symptoms but her blood work came back waaaay off the chart ! It was a shock. Her bippsy showed subtotal atrophy.

When were you diagnosed ?

That is the best I can do.  That is all of my genetic results.  USA may not get so detailed results.

You dont have double copies of DQ2 you have DQ2 and DQ8 which also means you could be very sensitive since you have both celiac genes.

Thanks.  I was diagnosed about 3 1/2 years ago.

This is interesting.  I wonder if this is why I get so sick.  I don't eat anything containing gluten but when I did before I would get very sick. 4 months after being diagnosed I decided to eat a donut and became very ill.   In a way it's good how sick I get because it keeps me from cheating.

      Going Low-Gluten May Harm Good Gut Bacteria, Researchers Warn

      Researchers are working on T cell modification therapy that could one day let celiacs eat gluten.

      Going Low-Gluten May Harm Good Gut Bacteria, Researchers Warn

      It's like a double edged sword.......we do one thing to improve a problem and cause another problem. I'd like to think the ultimate cure might be something that would train or modify the body to prevent the damage that gluten causes.

      GI DX celiac despite neg serology and no biopsy

      Celiac disease requires both genetic potential and a triggering stress event to activate the genes. Otherwise it remains dormant and only a potential problem.

      Yes, i pulled raw ancetry data and saw i have 2/3 markers for DQ2.2 but have heard from friends in genetics that this raw data can be wildly innacurate

But if you don't have the genes, the symptoms are likely being caused by something else.

      Shingles - Could It Be Related to Gluten/ Celiac

      By Ginger38 · Posted

      Thanks, I’m still dealing with the pain and tingling and itching and feeling like bugs or something crawling around on my face and scalp. It’s been a miserable experience. I saw my eye doc last week, the eye itself was okay, so they didn’t do anything. I did take a 7 day course of an antiviral. I’m hoping for a turnaround soon! My life is full of stress but I have been on / off the gluten free diet for the last year , after being talked into going back on gluten to have a biopsy, that looked okay. But I do have positive antibody levels that have been responsive  to a gluten free diet. I can’t help but wonder if the last year has caused all this.

      I don't think any apps are up to date, which is exactly why this happened to you. Most of the data in such apps is years old, and it doesn't get updated in real time. Ultimately there is no substitution for learning to read labels. The following two lists are very helpful for anyone who is gluten sensitive and needs to avoid gluten when shopping. It's very important to learn to read labels and understand sources of hidden gluten, and to know some general information about product labelling--for example in the USA if wheat is a possible allergen it must be declared on a product's ingredient label like this: Allergens: Wheat.
