Gene Test Results Negative
0

8 posts in this topic

Here are my gene test results, so it seems it is NOT celiac. Which is good news for my relatives. :) I guess this narrows what I have down to NCGI, but my GI doc is doing an endo in a couple weeks anyway....

I'm not doubting the interpretation, but can anyone decipher what this means? I get what the first two are and am lost after that.

---------------------------------

Interpretation --- The patient does not have the HLA-DQ variants associated with celiac disease.

More than 97% of celiac patients carry either HLA-DQ2(DQA1*05/DQB1*02) or HLA-DQ8(DQA1*03/DQB1*0302) or both.

Hla-Dq2 Negative

Hla-Dq8 Negative

Hla-Dqa1 -- 01

Hla-Dqa1 -- 02

Hla-Dqb1 -- 0303

Hla-Dqb1 -- 0603

Unless you are in the 3% that don't have the genes they test for?

Oh.... I didn't think of that. Maybe that's why he's doing the scope anyway. <_<

I was told if I don't have the genes, I ain't celiac (I don't have the genes). Does anyone have any information about the other 3%?

So my GI seems to be sure I am celiac negative, given my blood tests were also neg. I'm at a loss as to why he's doing the endo, plus I'm supposed to start a gluten challenge on Sunday. Why would I do a gluten challenge and biopsy if he is convinced I'm negative anyway?

I tend to think that I'm probably not in that "less than 3 percent" group -- I mean those are pretty slim odds. I have to accept that all of the most sophisticated tests say I'm not celiac. I guess the biopsy will be the last test.

I'm kind of freaking out about what to do next because I still can't eat gluten and I seem to have a wheat allergy, as in the puffy face and all. So little is known about NCGI... Are all the potential complications the same? Do I need to be as strict? I don't mind being gluten-strict in my own home, but I do sometimes feel bad giving friends and family the once-over in their own kitchens. Can I lay off them a little if I don't have celiac?? :(

Also, does anybody know what the last four gene tests mean, if anything?

Hla-Dqa1 -- 01

Hla-Dqa1 -- 02

Hla-Dqb1 -- 0303

Hla-Dqb1 -- 0603

Actually, I've read studies wherein they've found up to 6-8% (I think) being negative for both the alpha and beta chains of DQ2 and DQ8 (which includes, by default, DQ7.5), the study had a very large cohort as well. Let me see if I can dig it up...

EDIT: Here are a couple I've read a long the way.... still digging for the study that showed only 93% of the celiac cohort showed DQ2 and/or DQ8.

    • When it's that high, it almost always means Celiac.  Sure, you can have Crohns, too.  Just like you can have Celiac and diabetes, the common cold or a hang nail.  I wouldn't jump to Chrohns.  I don't think the tTg really has anything to do with Chrohns?  Where did you see that?  Sometimes, a slightly elevate tTg can be elevated from other issues, but >100 is not a " slightly elevated" reading
    • Hi! I'm new here, and I'm looking for some information because I'm having a hard time finding it.  Over Labor Day weekend I got some kind of intestinal bug. I didn't think much of it until the D persisted once a day up til now. I tried a priobiotic but that didn't help much. I have bad anxiety and began to think that I was just anxious and stressed. No fever, no pain, all bloodwork is normal, so no infection or anemia. My mother has 5 siblings and 3 have celiac. One other one had a high result on a blood test but was never officially diagnosed and insists she doesn't have it. So I went to my local health fair and got the ttg-iga test, just in case. My result came back at >100. So I have called and scheduled a visit with a GI for next week. Aside from the recent intestinal issues I have never thought that I had any signs of celiac. I do have dermatographism and have had that since I was 20 (I am 28). I have severe anxiety. I had PUPPPS when I was pregnant with my daughter and it was miserable. It looks much like the skin rashes that celiacs have. Again, didn't think much of it. Because of my anxiety I am terrified that this high blood test is from something else, like crohn's. I don't have diabetes, my liver and thyroid numbers are fine. I think it's much more plausible that this is celiac because of my family history. But my anxiety says "what if it's crohns?" Does anyone have any insight? Is it true that the ttg iga can be elevated from crohns and not celiac? Is >100 pretty definitive of celiac? I didn't know if crohns was the cause if the number would be this high.  I'm just freaked out. 
    • This does say it is for NCGS....so not  for Celiacs.  There is a drug being developed that may actually break down the gluten in the stomach before it hits the intestines.  However, that is still in clinical trials.
    • could be from your neck, or it is, literally, in your head. perhaps a scan is needed.
    • The anxiety thing is there I take teas, and supplements along with CBD oil to help with it, and long walks and exercise when I get antsy. As for the human interaction it is a mix of other mental issues, and the way I feel about people who can eat gluten. If they are not eating I have no issue talking with people. I mentioned I have issues accepting them as the same species when I see them eating. My reaction to gluten is so ingrained in me that it is not a food but a poison, that watching others eat it causes a subconscious reaction where I find myself avoiding them and looking down on them like something from another planet. I end up disgusted with them and walking away, I will go out of my way to avoid people and places where foods like this are present. This is my TRAUMA part of the gluten exposure, and one of the big things I am trying to address in my life right now. I know it is irrational to do so but I end up doing it, I have never cared about others race, religion, or looks, but if I see them eating a gluten/poison, it somehow changes how I perceive them and interact with them and I hate this part about me. It is taking a lot of mental effort to try to smile and treat them as a human, and not something to be looked down upon in disgust. I just recall that mental state that gluten puts me in with my mind and body turning against me and not doing what I will it and the fear comes back. This diet is pretty much like mine, I take Doctors best Magnesium powder in a tea that is actually brewed with st johns wort (never thought much of it) , I use Liquid Health Stress & Energy along with the Neurologic Support they have, twice-three times a day for B vitamins(along with a bunch of other supplements) . I can not digest meats or carbs well, meats it is a issue with breaking them down same with egg yolks, I literally just burp up the undigested meats hours later. I have found the only way to eat them is to boil/slow cook them til they melt then blend them into a broth and have it with digestive enzymes so only do it with turkey bacon, longhorn, and salmon in small amounts in soups or for flavoring stock for stir frys.  As for Carbs like rice and potatoes I end up getting really gassy and bloated, same with sugars in any amount greater then like the size of my thumb give or take. Oats I only have gluten-free Harvest in about a tbsp amount when tasting recipes of stuff I sell at farmers markets. So I eat mostly fats and protein from egg whites, nuts, seeds, veggies, and vegan protein powders blends balanced for complete proteins. I have at least 1-2 dried fig, dates, handful of banana chips, or a 1/4 of a small fruit with meals for fruits.  My meals are mostly egg white and veggie omelettes, stir frys, and soups, Always with lots of fats and proteins in each meal. I have found having nutritional yeast to help with my mood and energy levels also and find someway of having it in meals often. I keep my foods on rotation and keep getting updated feed back on ratios with my dietician. I also have a rather odd list of foods I can not eat due to allergies/intolerance.
