Would You Help Me Figure Out What My Genetic Test Results Mean?

[SiandAshs Mom]

Hello all, 

I recently ordered a genetic celiac test and got the results back. It says, "This patient has a genetic predisposition to celiac disease." But then one part says my risk factor is below the average population - and I have no idea what DQ I am or what that even means... Here's what it says...

 

Locus                         AG1                                      AG2

DQB1                         03:XPFJ                               03:XPFJ

Ser. Equiv                   DQ3                                    DQ3

Allelic results         a whole string of DQB1 plus a bunch of numbers I can post if needed...

DQA                           03:MN                                  05:CMM

Ser. Eqiv                    no corr. antigen                   no corr. antigen

Allelic results              DQA1*03:01/02/03              DQA1*05:05/09/11   

 

 

What does this mean? I really have no idea! And I already had a attg iga blood test done that came back negative (if that makes any difference). Thanks

Anyone? It has a part that explains my genetic risk profile. It says I am DQX.5 which means my risk ratio is 1:1842 which is significantly less risk than the general population. Does this mean celiac disease is highly unlikely for me? If my husband passed on a celiac gene to our kids and they got the gene from me as well is their risk significantly increased? I'm assuming risk is related to the gene they would receive from my husband, right? Also, could the gene I carry cause non-celiac gluten sensitivity? Is there any info on that anywhere? Sorry for all the questions - I really didn't get a lot of info from the company that did the testing so I'm just trying to make sense of it all.

I think you got no answers because this looks like an incomplete report? What company did this test? Genetic stuff is very hard to understand.  Just remember that - 30% of the US population have at least 1 "gene" for Celiac but only about 1% of the population have Celiac.  Just having a gene piece or two does not mean you have Celiac disease.

 

 And the TTG test - did they test total serum IGA?  Without that test,negative results don't mean much.

First, there is no known testing for Gluten Intolerance.  Second, I'm assuming you have a reason to suspect Celiac Disease?  If so then you should discuss your concerns with your Doctor.  As you know, we are not Gene Specialists here.  I really have no idea what your results mean.  These results do not show the two genes they look for in Celiac Disease, DQ2 and 8 I believe.  Maybe you can contact the test company for further explanations. 

 

Sorry I could not help you further.  Good luck.

I missed the gluten sensitivity part - no known genes for that.  no known test for that.  Current research is heading towards NCGS actually being several other "conditions" .  However, more research is needed and is ongoing.

Thanks for posting - here's the website Open Original Shared Link . This is the results that they emailed to me. They are also mailing me the report so hopefully there is more info in that. My doctor did run a total IGA and it was normal. Looks like celiac isn't the answer. I appreciate your thoughts!

Thanks Colleen. Yes, I have a lot of symptoms but no diagnosis from doctors other than IBS, depression, and iron deficiency. I have discussed my concerns and haven't gotten any answers. I've been trying to do what I can to figure things out. If the report they mail to me doesn't contain any more info then I will contact them directly. I just thought someone here may be able to shed some light on the results. I appreciate you taking the time to read and respond

If you care to discuss it further, do you have a history?   Why did you do this test instead of an antibody tests?  Were you tested for DQ2 and Dq8?  You may not have been checked for celiac at all.

 

Did you have a total IgA test alone?  The total IgA would show that you don't have low antibodies only, I believe.  This would only mean that your test would not false negative for that reason.

 

Did you try a gluten free diet?  Did you notice changes after going gluten free?

 

You do have symptoms that could be celiac.  They could be something else.  Yet, please be sure that you have been checked carefully for celiac as it is serious and often is misdiagnosed.  Better now than later.

Thanks for responding. I did have the ttg iga test done and it was negative (ttg iga is the only celiac blood test available here - they don't ever run a full celiac panel and only run the ema test if ttg iga is positive). Since I still had symptoms which improved on a gluten free diet, I wanted to have the gene test done. My kids have symptoms as well and I wanted tools to advocate for them - I knew I could rule out celiac if my genetic test came back negative. 

The company that produces this gene test is the same company that makes the biocard/celiacsure at-home attg blood test. The gene test is specifically for celiac, so I'm sure the confusion lies in my ineptitude in reading the results!

From the research I have been doing, I think I have half of a DQ2 gene and half of a DQ8 (DQ2 is apparently DQA1*05/DQB1*02 - I have the DQA1*05 allele - and DQ8 is DQA1*03/DQB1*0302 - I have the DQB1*03 allele). I don't know if I am reading this correctly, but when I get the paper copy of my results I will call them and speak to them directly. I just think their results are a little more difficult to read than others. 

I actually just did the biocard attg blood test on my little guy last night and the results were a very faint positive. I plan on taking him in to the doctor to see if he'll send him for the lab tests.

Thanks so much for your thoughts and advice. All the best
