Does Type/amount Of Genes Make A Difference?

I have been trying to look up a question on the internet but cannot get an answer.

The people on this site seem to have more knowledge of celiac than anywhere else you hopefully you can help.

Does it make a difference to the likelihood of having celiac if you have certain combinations of the DQ2 and DQ8 genes?

If my son has both DQ8 genes and both DQ2 genes does that make him any more likely to have celiac than say someone with only one, or a combination of 2 genes??

Just curious.

Thanks,

Peta

Read this. :) You'll probably find it elucidating. :)

The HLA-DQ2 Gene Dose Effect in Celiac Disease is Directly Related to the Magnitude and Breadth of Gluten-Specific T-Cell Reponses

Combinations of DQ2 and DQ8, or DQ2 and DQ2, or DQ8 and DQ8, are all high susceptibility factors for celiac disease. Your son would have a higher chance of getting celiac disease, and the potential for a more severe dietary reaction to gluten. I'm not sure if this answers your question, but I hope it helps.

Thankyou for your responses.

I have SOOOO many questions that I wish I could connect my computer directly into your brains and extract all that wonderful information....as I'm hesitant to drive you all mad on this site by asking my hundreds of mindless questions!

Ask all the questions you want.

When a question gets asked someone pulls up another article I haven't read yet. So you help so many people in the long run.

      Scott, I am mostly asymptomatic. I was diagnosed based on high antibodies, low ferritin (3) and low vitamin D (10). I wasn't able to get in for the biopsy until 3 months after the blood test came back. I was supposed to keep eating gluten during this time. Well why would I continue doing something that I know to be harmful for 3 more months to just get...

      Supplements for those Diagnosed with Celiac Disease

      I was undiagnosed for decades. My ferritin when checked in 2003 was 3. It never went above 10 in the next 20 years. I was just told to "take iron". I finally requested the TTgIgA test in 2023 when I was well and truly done with the chronic fatigue and feeling awful. My numbers were off the charts on the whole panel. they offered me an endoscopic biopsy ...

      Is it gluten?

      Scott, I agree with everything you said except the term "false negative". It should be a "true negative" just plain negative. I actually looked up true/false negative/positive as it pertains to testing. The term "false negative" would be correct if you are positive (have anti-bodies) and the test did not pick them up. That would be a problem with the "test...

      IBS-D vs Celiac

      I realized it is actually important to get an official diagnosis because then insurance can cover bone density testing and other lab work to see if any further damage has been done because of it. Also, if hospitalized for whatever reason, I have the right to gluten-free food if I am officially celiac. I guess it gives me some legal protections. Plus, I have...

      Scott, I am mostly asymptomatic. I was diagnosed based on high antibodies, low ferritin (3) and low vitamin D (10). I wasn't able to get in for the biopsy until 3 months after the blood test came back. I was supposed to keep eating gluten during this time. Well why would I continue doing something that I know to be harmful for 3 more months to just get this test? So I did quit gluten and had the biopsy. It was negative for celiacs. I continued gluten free with iron supps and my ferritin came back up to a reasonable, but not great level of around 30-35.  Could there be something else going on? Is there any reason why my antibodies would be high (>80) with a negative biopsy? could me intestines have healed that quickly (3 months)?  I'm having a hard time staying gluten free because I am asymptomatic and i'm wondering about that biopsy. I do have the celiacs gene, and all of the antibody tests have always come back high. I recently had them tested again. Still very high. I am gluten free mostly, but not totally. I will occasionally eat something with gluten, but try to keep to a minimum. It's really hard when the immediate consequences are nil.  with high antibodies, the gene, but a negative biopsy (after 3 months strict gluten-free), do i really have celiacs? please say no. lol. i think i know the answer.  Asa

      I have had a long year of testing unfortunately still not diagnosed , although one thing they definitely agree I'm gluten intolerant, the thing for me I have severe back troubles they wouldnt perform the tests and I couldn't have a full MRI because I'm allergic to the solution , we tryed believe me  I tryed lol , another was to have another blood test after consuming gluten but it makes me so bad I tryed it for only a week, and because I have a trapped sciatic nerve when I get bad bowels it sets that off terribly so I just take it on myself now , I eat a gluten free diet , I'm the best I've ever been , and if I slip I know it so for me i have my own diagnosis  and I act accordingly, sometimes it's not so straight forward for some of us , for the first time in years I can plan to go out , and I have been absorbing my food better , running to the toilet has become occasionally now instead of all the time , i hope you find a solution 🤗

I finally requested the TTgIgA test in 2023 when I was well and truly done with the chronic fatigue and feeling awful. My numbers were off the charts on the whole panel.  they offered me an endoscopic biopsy 3 months later, but that i would need to continue eating gluten for it to be accurate. so i quit eating gluten and my intestine had healed by the time i had the biopsy (i'm guessing??). Why else would my TTgIgA be so high if not celiacs? Anyway, your ferritin will rise as your intestine heals and take HEME iron (brand 4 arrows). I took 20mg of this with vitamin c and lactoferrin and my ferritin went up, now sits around 35.  you will feel dramatically better getting your ferritin up, and you can do it orally with the right supplements. I wouldn't get an infusion, you will get as good or better results taking heme iron/vc/lf.

I actually looked up true/false negative/positive as it pertains to testing. The term "false negative" would be correct if you are positive (have anti-bodies) and the test did not pick them up. That would be a problem with the "test" itself. If you were gluten-free and got tested, you more than likely would test "true" negative or just negative. This means that the gluten-free diet is working and no anti-bodies should be present. I know it sounds confusing and if you don't agree feel free to respond.

If I really do have it then they may have increased risk.
