Genetic Test Results Are Confusing!

I've had these results for a bit and find that I still really don't understand them. In talking to medical professionals, they talk about my set of genes as predisposing me to neurological problems rather than classic GI symptoms. I also thought that they said a minority of patients in Dr. H's (long named gluten researcher) studies had celiac with this gene set, but I'm not sure of that.

I have full access to medical research, journals, etc. and would love to learn more. However, I don't get the lingo enough to research properly. The summary indicates two copies of gluten intolerant genes and that they are not the classic celiac combo. Can someone help interpret please?

Thanks so much. That is great info. I remember reading an article where a small minority were not DQ2 and DQ8. Where several members in a confirmed small celiac group had other genes. I have to find that again!

Found it! Here's a quote from the article.

Open Original Shared Link

"Eight of the 122 celiac disease patients lacked both the heterodimer and the DRB104 alleles; therefore, we further screened the DQB1 locus to investigate if other alleles were present in association to celiac disease (2)(14). Two of these eight celiac disease patients showed the DQ2 molecule (DQB10201 allele in heterozygosis); but one of them carried also the DQB10501 allele, also found in Sardinian patients to be associated to celiac disease (15); four showed the DQ7 molecule (DQB10304 or DQB10301 alleles). Another patient carried the DQ8 molecule encoded by the DQB10302 allele, and the remaining patient had the haplotype DQB10501 in homozygosis (15). The DQ8 molecule seems to be an alternative to DQ2 in influencing susceptibility towards celiac disease, being present in up to 20% of celiac patients not bearing of DQ2 in the Mediterranean area (2)(14)(16). Our data do not support an earlier finding that HLA-DQ7 is a nonsusceptible molecule (2). In fact, DQ7 was present in 50% of our celiac disease patients in the absence of the heterodimer and of the DRB104 alleles. Because the DQ7 molecule is very similar to the DQ8 molecule, it could alternatively present similar gluten-derived peptides to restricted T cells (17). DQ7 has been detected in a few celiac disease cases in the absence of DQ2 but in association with the DRB104 alleles (18)."

      Does anyone here also have Afib

      By Scott Adams · Posted

      If black seed oil is working for his Afib, stick to it, but if not, I can say that ablation therapy is no big deal--my mother was out of the procedure in about 1 hour and went home that evening, and had zero negative effects from the treatment. PS - I would recommend that your husband get an Apple watch to monitor his Afib--there is an app and it will take readings 24/7 and give reports on how much of the time he's in it. Actual data like this should be what should guide his treatment.

      Covid caused reoccurrence of DH without eating gluten

      By Jacki Espo · Posted

      This happened to me as well. What’s weirder is that within a couple hours of taking paxlovid it subsided. I thought maybe I got glutened but after reading your post not so sure.

      New Celiac Mama in My 30s

      By Mari · Posted

      Hi Tiffany. Thank you for writing your dituation and  circumstancesin such detail and so well writte, too. I particularly noticed what you wrote about brain for and feeling like your brain is swelling and I know from my own experiences that's how it feel and your brain really does swell and you get migraines.    Way back when I was in my 20s I read a book by 2 MD allergist and they described their patient who came in complaining that her brain, inside her cranium, was swelling  and it happened when she smelled a certain chemical she used in her home. She kept coming back and insisting her brain actually swelled in her head. The Drs couldn't explain this problem so they, with her permission, performed an operation where they made a small opening through her cranium, exposed her to the chemical then watched as she brain did swell into the opening. The DRs were amazed but then were able to advise her to avoid chemicals that made her brain swell. I remember that because I occasionally had brain fog then but it was not a serious problem. I also realized that I was becoming more sensitive to chemicals I used in my work in medical laboratories. By my mid forties the brain fog and chemicals forced me to leave my  profession and move to a rural area with little pollution. I did not have migraines. I was told a little later that I had a more porous blood brain barrier than other people. Chemicals in the air would go up into my sinused and leak through the blood brain barrier into my brain. We have 2 arteries  in our neck that carry blood with the nutrients and oxygen into the brain. To remove the fluids and used blood from the brain there are only capillaries and no large veins to carry it away so all those fluids ooze out much more slowly than they came in and since the small capillaries can't take care of extra fluid it results in swelling in the face, especially around the eyes. My blood flow into my brain is different from most other people as I have an arterial ischema, adefectiveartery on one side.   I have to go forward about 20 or more years when I learned that I had glaucoma, an eye problem that causes blindness and more years until I learned I had celiac disease.  The eye Dr described my glaucoma as a very slow loss of vision that I wouldn't  notice until had noticeable loss of sight.  I could have my eye pressure checked regularly or it would be best to have the cataracts removed from both eyes. I kept putting off the surgery then just overnight lost most of the vision in my left eye. I thought at the I had been exposed to some chemical and found out a little later the person who livedbehind me was using some chemicals to build kayaks in a shed behind my house. I did not realize the signifance  of this until I started having appointments with a Dr. in a new building. New buildings give me brain fog, loss of balance and other problems I know about this time I experienced visual disturbances very similar to those experienced by people with migraines. I looked further online and read that people with glaucoma can suffer rapid loss of sight if they have silent migraines (no headache). The remedy for migraines is to identify and avoid the triggers. I already know most of my triggers - aromatic chemicals, some cleaning materials, gasoline and exhaust and mold toxins. I am very careful about using cleaning agents using mostly borax and baking powder. Anything that has any fragrance or smell I avoid. There is one brand of dishwashing detergent that I can use and several brands of  scouring powder. I hope you find some of this helpful and useful. I have not seen any evidence that Celiac Disease is involved with migraines or glaucoma. Please come back if you have questions or if what I wrote doesn't make senseto you. We sometimes haveto learn by experience and finding out why we have some problems. Take care.       The report did not mention migraines.

      My only proof

      By Mari · Posted

      Hi Jmartes71 That is so much like my story! You probably know where Laytonville is and that's where I was living just before my 60th birthday when the new Dr. suggested I could have Celiacs. I didn't go on a gluten challange diet before having the Celiac panel blood test drawn. The results came back as equivical as one antibody level was very high but another, tissue transaminasewas normal. Itdid show I was  allergic to cows milk and I think hot peppers. I immediately went gluten free but did not go in for an endoscopy. I found an online lab online that would do the test to show if I had a main celiac gene (enterolab.com). The report came back that I had inherited a main celiac gene, DQ8, from one parent and a D!6 from the other parent. That combination is knows to sym[tons of celiac worse than just inheriting one main celiac gene. With my version of celiac disease I was mostly constipated but after going gluten-free I would have diarrhea the few times I was glutened either by cross contamination or eating some food containing gluten. I have stayed gluten-free for almost 20 years now and knew within a few days that it was right for me although my recovery has been slow.   When I go to see a  medical provide and tell them I have celiacs they don't believe me. The same when I tell them that I carry a main celiac gene, the DQ8. It is only when I tell them that I get diarrhea after eating gluten that they realize that I might have celiac disease. Then they will order th Vitamin B12 and D3 that I need to monitor as my B12 levels can go down very fast if I'm not taking enough of it. Medical providers haven't been much help in my recovery. They are not well trained in this problem. I really hope this helps ypu. Take care.
