Dq8 - Results?

I was just wondering if any of you knew why just having the DQ8 gene is so rare? My doc said that you normally see DQ2 along with it but I only have the one. Does anyone know the significance of this and what it could mean for my sons? I have 2 that are displaying classic celiac symptoms. Although one of them keeps having green and black stools. (food dyes have not been ingested). Should I get the dna tested on them? Any help would be greatly appreciated.

I don't know. DQ2 and/or DQ8 predispose to gluten sensitivity/intolerance. Out of the four of us in my family tested, one has DQ8, one has DQ2 & DQ8, one has two DQ2, and one has one DQ2. From enterolab DQ2 or DQ8 are celiac genes but they don't go into just the 8 being rare alone. If you only have the one celiac gene than you're offspring has a 50% chance of that gene being passed on to them. My daughter has the DQ8 and my son has both DQ2. She also has a gene that predisposes to gluten sensitivity, so one of each. I'll be curious to see what combo my baby has. We will get him tested when we scrape the funds together. We know he'll have at least one celiac gene. The following is what enterolab had to say about my daughter.

Interpretation Of HLA-DQ Testing: HLA gene analysis reveals that you have one of the main genes that predisposes to gluten sensitivity and celiac sprue, HLA-DQ2 or HLA-DQ8. Each of your offspring has a 50% chance of receiving this gene from you, and at least one of your parents passed it to you. You also have a non-celiac gene predisposing to gluten sensitivity (DQ1 or DQ3 not subtype 8). Having one celiac gene and one gluten sensitive gene, means that each of your parents, and all of your children (if you have them) will possess at least one copy of a gluten sensitive gene. Having two copies also means there is an even stronger predisposition to gluten sensitivity than having one gene and the resultant immunologic gluten sensitivity or celiac disease may be more severe.

I dont recall ever hearing or reading that DQ8 is rare without DQ2. :unsure: I think lots of people here have DQ8 by itself.

I googled DQ8 and found that only 5 to 10% possess that gene. Maybe it means the symptoms are more disturbing to life since almost everyone who messages here has it.

I never heard anyting rare about having only the DQ8 either. My grandson has it and the doctors at children's hospital in Pittsburgh never made any comment.

I haven't heard much about this lab, but we used the Kimball Genetics Lab. My son has 1/2 of the DQ2 allele and they claim that it is possible for him to have celiac even with only half---but rare.

Anyone know any more?

I only have DQ8 not DQ2. I also have a gluten sensitivity gene.

Do not be misled into thinking that DQ1 is "only" a gluten sensitive gene. It is as bad or worse than DQ2 or DQ8. If you read the book Dangerous Grains it goes into the gluten sensitivity and really portrays it as worse than celiac as it the umbrella that celiac disease is under.

re the son that has DQ8 & symptoms, I would bet that he also has one DQ1.

There are only two labs in the U.S. that test for DQ1, enterolab.com is one & I do not know the other one.

I have DQ1...I also have alot of damage....malabsorption was almost severe and I'm still suffering multiple intolerances. I've heard that this is a very bad gene with regards to gluten sensitivity. I dont have either DQ2 or DQ8....no Celiac genes. Along with the DQ1 I have DQ3. I've read Dangerous Grains...however, I dont recall mention of the DQ1 gene.

I'd like to know where I might find some articles on DQ1....particularly with regards to severity of symptoms. The Braintalk board was a good resource but I'm hearing its closed now. Are you from that board?

Hi Rachel, yes I am from that board, geez, are they not going to get it going again? That would be a shame if they do not. If they do not, they need to move their posts to the list serv.

There were a lot of us DQ1 people on there. I have read that board everyday for the past 2 years. I am in withdrawal :blink:

& yes, DQ1 comes with the potential for a lot of damage. I was under the impression that DQ3 is a celiac gene. Also there are a couple of celiac genes that they know are out there because of people that have a biopsy diagnoses but do not have DQ1, DQ2, DQ8 or DQ3

Unfortunately I lost my hard drive early this year & I lost all my links :angry:

You could start a DQ1 thread, if there is not one already. I have not learned how to search on here etc.

I have a lot of intolerances "allergies" myself, it is worse than the no gluten, which is no problem for me because I was severely "allergic" to barley & oats since I was 25 (& that was a long time ago :lol: ) Which meant that I could not eat any wheat thing that was bought because everything has barley malt in it & I mean everything, I made my own bread etc. Then 12 years ago I met a woman that had celiac & was gluten-free & migrain free, she told me if I would quit eating wheat that my other food allergies would get better. well I resisted for awhile, but I was getting desperate ( had a bladder infection every month & was living on antibiotics) so thinking allergies, I went mostly wheat free (I was already oat & barley free). I would go to my sons house every few months & cheat - get sick, thinking allergy I would go back on my regular diet., Did this over & over for 10 years, until 2 years ago, when I was looking up Hemochromatosis. which runs in the Irish side of our family, I had just found out from a relative that we had found. From Hemochromatosis I got to celiac & what an eye opener that was. I knew I had celiac & could pick it out in my grandchildren & my family & my mother that I now know had mental issues & she died from stomach or intestinal cancer.

I have a 10 year old grandson that also has two DQ1 genes, one from my son & one from my d-i-l- who has dyslexia & her mom has IBS, osteoporosis, & a ton of other celiac symptoms - but I am the only one on the gluten-free diet. My son has had it since he was a baby but is in total denial & took his kids off the gluten-free diet after I had them on it for 6 months, well mostly - he would take them to the movies & feed them hotdogs :huh:

well this has gotten long, that is about all of my "story".

      Newly diagnosed mam to coeliac 11 year old

      By trents · Posted

      Welcome to the celic.com community @Dizzyma! I'm assuming you are in the U.K. since you speak of your daughter's celiac disease blood tests as "her bloods".  Has her physician officially diagnosed her has having celiac disease on the results of her blood tests alone? Normally, if the ttg-iga blood test results are positive, a follow-up endoscopy with biopsy of the small bowel lining to check for damage would be ordered to confirm the results of "the bloods". However if the ttg-iga test score is 10x normal or greater, some physicians, particularly in the U.K., will dispense with the endoscopy/biopsy. If there is to be an endoscopy/biopsy, your daughter should not yet begin the gluten free diet as doing so would allow healing of the small bowel lining to commence which may result in a biopsy finding having results that conflict with the blood work. Do you know if an endoscopy/biopsy is planned? Celiac disease can have onset at any stage of life, from infancy to old age. It has a genetic base but the genes remain dormant until and unless triggered by some stress event. The stress event can be many things but it is often a viral infection. About 40% of the general population have the genetic potential to develop celiac disease but only about 1% actually develop celiac disease. So, for most, the genes remain dormant.  Celiac disease is by nature an autoimmune disorder. That is to say, gluten ingestion triggers an immune response that causes the body to attack its own tissues. In this case, the attack happens in he lining of the small bowel, at least classically, though we now know there are other body systems that can sometimes be affected. So, for a person with celiac disease, when they ingest gluten, the body sends attacking cells to battle the gluten which causes inflammation as the gluten is being absorbed into the cells that make up the lining of the small bowel. This causes damage to the cells and over time, wears them down. This lining is composed of billions of tiny finger-like projections and which creates a tremendous surface area for absorbing nutrients from the food we eat. This area of the intestinal track is where all of our nutrition is absorbed. As these finger-like projections get worn down by the constant inflammation from continued gluten consumption before diagnosis (or after diagnosis in the case of those who are noncompliant) the efficiency of nutrient absorption from what we eat can be drastically reduced. This is why iron deficiency anemia and other nutrient deficiency related medical problems are so common in the celiac population. So, to answer your question about the wisdom of allowing your daughter to consume gluten on a limited basis to retain some tolerance to it, that would not be a sound approach because it would prevent healing of the lining of her small bowel. It would keep the fires of inflammation smoldering. The only wise course is strict adherence to a gluten free diet, once all tests to confirm celiac disease are complete.

      Newly diagnosed mam to coeliac 11 year old

      Hi all, I have so many questions and feel like google is giving me very different information. Hoping I may get some more definite answers here. ok, my daughter has been diagnosed as a coeliac as her bloods show anti TTG antibodies are over 128. We have started her  on a full gluten free diet. my concerns are that she wasn’t actually physically sick on her regular diet, she had tummy issues and skin sores. My fear is that she will build up a complete intolerance to gluten and become physically sick if she has gluten. Is there anything to be said for keeping a small bit of gluten in the diet to stop her from developing a total intolerance?  also, she would be an anxious type of person, is it possible that stress is the reason she has become coeliac? I read that diagnosis later in childhood could be following a sickness or stress. How can she have been fine for the first 10 years and then become coeliac? sorry, I’m just very confused and really want to do right by her. I know a coeliac and she has a terrible time after she gets gluttened so just want to make sure going down a total gluten free road is the right choice. thank you for any help or advise xx

      Severe severe mouth pain

      By Russ H · Posted

      Hi Charlie, You sound like you have been having a rough time of it. Coeliac disease can cause a multitude of skin, mouth and throat problems. Mouth ulcers and enamel defects are well known but other oral conditions are also more common in people with coeliac disease: burning tongue, inflamed and swollen tongue, difficulty swallowing, redness and crusting in the mouth corners, and dry mouth to name but some. The link below is for paediatric dentistry but it applies to adults too.  Have you had follow up for you coeliac disease to check that your anti-tTG2 antibodies levels have come down? Are you certain that you not being exposed to significant amounts of gluten? Are you taking a PPI for your Barrett's oesophagus? Signs of changes to the tongue can be caused by nutritional deficiencies, particularly iron, B12 and B9 (folate) deficiency. I would make sure to take a good quality multivitamin every day and make sure to take it with vitamin C containing food - orange juice, broccoli, cabbage etc.  Sebaceous hyperplasia is common in older men and I can't find a link to coeliac disease.   Russ.   Oral Manifestations in Pediatric Patients with Coeliac Disease – A Review Article
