Gene Test Results Negative


gatita

Recommended Posts

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%?

ravenwoodglass belongs in that 3%. You can find out what it did to her :wacko:

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

OK answering some of my own questions here :) . It looks like the Hla-Dqb1 -- 0303 is the same as DQ9? Is that right? And DQ9 is now possibly linked to a "pre-disposure" to celiac and/or gluten intolerance:

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.

      The anti-endomysial antibody test is an old test that is generally reported as positive or negative - a lab technician looks down a microscope to check for fluorescence of the sample. It is less sensitive but more specific for coeliac disease than IgA tTG2. Hence, it is not "barely positive" - it is positive. People diagnosed in childhood recover much more quickly than adults.  I would look at testing all 1st degree relatives - parents, siblings.

      What about digestive enzymes that I hear help? I take align 5x probiotics daily.

      thank you RMJ! That is very helpful advice. Good to know we aren’t crazy if we don’t do the endoscopy. We are going to try the gluten free and see how symptoms and levels improve.    thank you Wheatwacked (love the username lol) that is also reassuring. Thankfully she has an amazing and experienced pediatrician. And yesss I forgot to mention the poop! She has the weirdest poop issues.    How long did it take y'all to start seeing improvement in symptoms?

      My son was diagnosed when he was weaned in 1976 after several endoscopies.  Given your two year old's symptoms and your family history and your pediatrition advocating for the dx, I would agree.  Whether an endoscopy is positive or negative is irrelevant.   That may happen even with endoscopy.  Pick your doctors with that in mind. In the end you save the potential trauma of the endoscopy for your baby.   Mine also had really nasty poop.  His doctor started him on Nutramigen Infant because at the time it was the only product that was hypo allergenic and had complete nutrition. The improvement was immediate.

      So her tissue transglutaminase antibody is almost 4x the upper end of the normal range - likely a real result. The other things you can do besides an endoscopy would be: 1.  Genetic testing.  Unfortunately a large proportion of the population has genes permissive for celiac disease, but only a small proportion of those with the genes have it. With family history it is likely she has the genes. 2.  Try a gluten free diet and see if the symptoms go away AND the antibody levels return to normal. (This is what I would do). Endoscopies aren’t always accurate in patients as young as your daughter. Unfortunately, without an endoscopy, some doctor later in her life may question whether she really has celiac disease or not, and you’ll need to be a fierce mama bear to defend the diagnosis! Be sure you have a good written record of her current pediatrician’s diagnosis. Doing a gluten challenge for an endoscopy later in life could cause a very uncomfortable level of symptoms.   Having yourself, your husband and your son tested would be a great idea.
