Need Help With Test Results


poopedout

Recommended Posts

poopedout Apprentice

I posted quite a long time ago and I decided to have genetic testing by Enterolab. I have not had much help from the medical profession. I saw the GI doc and he refused to do the gene testing and grudgingly agreed to do a ttg IgA but not a total IgA. I have not had that test yet as I had to go back to eating gluten after being gluten free for six months. I have been eating gluten for almost three weeks now and I am worse on gluten but not drastically so.

The results of my gene testing is : HLA-DQB1, Allele 1 0301

HLA-DQB1, Allele 2 0602

The interpretation is that I have two copies of a gene that predisposes to gluten sensitivity but not to celiac. Since I have two copies, I am more predisposed to having gluten sensitivity and it could be more severe.

I am not sure how to interpret this. It looks like eating gluten will not harm me. It will just make me sick, but it will not cause villous atrophy or blunting or whatever. How do I know if I have gluten sensitivity since there is no test for it other than my own subjective and biased interpretation of what happens after I eat gluten?

Does anyone know if I could have celiac with these genes or if they are present in other conditions like microscopic colitis?

Please help me to solve the mystery.

That is DQ7 and DQ6.

But DQ7 differs from DQ8 by just a tiny tiny bit, and most DQ7 but not all have the 05* alpha chain.

So ou could have half the DQ2,5 gene, the 05* alpha chain.

If you try some other gene testing, they might confirm it. Those that test for alpha chains, mainly the 05* alpha chain.

It is officially a celiac gene but lesser so, and they ahve started to test for it I think about three years ago.

(but not Enterolab, and they get their testing done somewhere else, I think it is still The American Red Cross and they order the beta chains only to keep costs down)

So if I am just "gluten sensitive" I can keep eating gluten and it will not harm me.

They also mention "immunologic gluten sensitivity" which can be more severe with having two genes. Does that mean that I probably produce anti-ttG antibodies but it will not lead to villous atrophy?

nora-n Rookie

You might be celiac, or gluten sensitive.

The other gene is DQ6, which is DQ1, and there are even a couple of forums for people like that out there. Many of them are DQ1. Being DQ1 and gluten sensitive is not just gluten sensitivity light, it might be more severe than celiac.

They can react to smaller amounts of gluten than the DQ2 celiacs.

If you google hadjivassiliou, you find numerous articles about neuro issues and gliadin. He found that about 20% of his gluten ataxia patients are DQ1.

In Europe, in some north european contries celaics eat wheat starch which is specially purified but has about 50-100 ppm gluten. DQ2 celiacs toreate this just fine, but not us DQ1. I get DH rashes from that stuff.

Should my GI take these results seriously? He is the one (also my family doctor) who said I am too old to have celiac disease. I suppose he will say it is "just gluten sensitivity".

No to both questions. Some doctors would call me 'gluten sensitive' since I don't have either DQ2 or DQ8 but as you can tell by my signature the effects gluten had on me were severe.

nora-n Rookie

Actually, they found that as people get older, more are celiac!

In Finland, they found that about 3% of old people were celiac by screening, and just around 1% of young people.

There is no known answer to this. Logic would tell you that eating something that makes you feel bad must be doing something bad to you

Dr. Peter Green says in his book that there are two types of gluten sensitivity. One is patients that improve when gluten is removed from their diet and relapse on re-introduction and the other is patients with positive blood tests for celiac disease but normal intestinal antibodies. I'm not sure what he is calling intestinal antibodies and which are the positive blood tests.

He does not write about any genes for gluten sensitivity in his book that I can find. Is that well known that there are genes for gluten sensitivity?

Commonly in the US the genes that are considered to be celiac associated genes are DQ2 or DQ8. Many times none of the other celiac associated genes are even looked for. Gene science is really in it's infancy, IMHO and in other coutries other genes are considered celiac related, like mine, but here some consider them to be 'gluten sensitivity' genes. IMHO they all are celiac associated. Gene testing can not be used to rule out celiac. They can provide a part of the diagnostic process but they are not the be all and end all that some doctors consider them to be.

They know about many more genes conributing to celiac, and HLA DQ is now only regarded to contribute to celiac risk with 40%.

The greatest risk is still having a sibling or close blood relative with celiac.

So is it only Enterolab who calls these genes gluten sensitivity genes and tests for them?

Jestgar Rising Star

Gene science is really in it's infancy,

The Raven is right. I do 'gene science' for a living and there are very few genes that have been found to directly correlate to a disease state. celiac disease is not among them. You can restate your question as many ways as you want, the bottom line is, there is no absolute answer. You can have none of the studied genes, and still have celiac disease, or you can have both of the studied genes and not have celiac disease. Gluten intolerance is so poorly studied, that any speculation on associated genes is purely just that, speculation.

I know you want answers, but right now, the hard answers you want don't exist.

My question is about the difference between the genes for celiac disease and the genes for gluten sensitivity. I did not know that there were different genes for gluten sensitivity and I have not found anyone else talking about them except on the Enterolab website. Is this just an Enterolab disctinction or is this something that is commonly held to be true?

Jestgar Rising Star

There are no 'genes for celiac disease', or 'genes for gluten sensitivity'. Period. There are genes that are associated with these conditions.

My problem is that I have received this report stating that each of my children has inherited a gluten sensitivity gene from me. I need to tell my sons about this but I do not know if this is bogus science or if it is real.

Jestgar Rising Star

I don't know the exact wording Elab uses, but there are only genes associated with different responses to gluten. There are no genes defined as causative.

What they say is that I have two copies of a gene that predisposes to gluten sensitivity so that means that each of my children will have one copy of the gene. What I am not sure of is whether there is a gene that predisposes to gluten sensitivity. I cannot find any information about it except on the Enterolab website.

nora-n Rookie

Aboout what to tell the children:

It is not so simple, or straight-forward.

Well, one must explain it is just about risk.

Not celiac genes, just risk.

As of now, the HLA DQ genes (which only contribute to celiac with about 40% anyway) which are most often found in celaics are HLA DQ2 and HLA DQ8.

DQ2 is 0501 0201 or trans by combining DQ2,2-0202 and 05* alpha which is in DQ7 (0301

DQ8 is 0301 0302

Then, there are half genes, the 05* alpha chain in DQ7

Then, DQ1 which 20% of gluten ataxia patients have.

DQ1 is split into DQ5 and DQ6

And then, there are diagnosed DQ9, especially in Japan where ther are a lot of DQ9 and few DQ2.

So that leaves only DQ4, double DQ4 which have not been found to be celiac or gluten sensitive.

To sum it up, DQ1 is DQ5 and 6

DQ2 is just DQ2 but there are DQ2,5 and DQ2,2

DQ3 is DQ7,8 and 9

then there is DQ4

So what Dr. Fine at Enterolab says, that all these except DQ4 are either celiac or gluten sensitive genes, is right.

In real life, 6% of celiacs test negative for DQ2 or DQ8.

But in these 6%, most have half a gene, meaning they have the the 05* alpha chain or just the 0201 beta chain. A few have DQ6 or DQ9(japan) Those are those who are officially diagnosed celiacs.

Then there is DH, and they do not have to have the DQ2 or DQ8 genes, and gluten ataxia, which can be DQ1....

If you go and google Ford Gluten, there are more, way more issues from gluten than just the small intestine celiac thing.

So if you get better from totally avoiding gluten, it is really better to stay off it.

All celiac testing is only about the shape of small intestine villi and crypt height and stuff.

Not about the antibodies that attack the brain.

Personally, I have gotten hashimotos triggered by gluten antibodies, and DH rash, and negative celiac tests because when I went back on the gluten challenge, they tested me too soon. And I went gluten free one week after the biopsy since I could not feel where my feet were. That is antigliadin attacking my brain.

google hadjivassiliou and read the papers on gluten ataxia.

What I am not sure of is whether there is a gene that predisposes to gluten sensitivity. I cannot find any information about it except on the Enterolab website.

Enterolab has found that some genes are more highly associated with gluten sensitivity. I believe they base their definition of gluten sensitivity on the production of antigliadin antibodies produced in the gut and found through stool testing. What they don't have is associated clinical data saying that people who produce these antibodies feel better when they stop eating gluten. What you will find, if you search this board, is that a lot of people got gs results from Elab,stopped eating gluten, and felt better.

You won't find anything about gs genes anywhere else, because no one else studies it. This doesn't mean it's not real, it just means it's hard to study.

So you tell your kids that you have two copies of a gene that's associated with problems eating gluten. They may want to consider cutting gluten out of their diet, if they have current health problems, or being aware that it may be the cause of future health problem. gs is a poorly studied disorder, and you hope that if they do develop health issues from gluten, they will have access to better information than you have.

Thanks for the great answer. That was just the kind of information I was looking for. I don't have any ataxia, but my husband might say my brain is missing something. I seem to have the genes that are commonly found in people with microscopic colitis. My symptoms fit that and microscopic colitis responds to a gluten free diet.

Thank you for the reply. You have answered my questions about the gluten sensitivity genes and now I know why I can't find information about them except from Enterolab. I did stop eating gluten before I knew anything about Enterolab and I was better but still had diarrhea. I am only back on gluten because I am having a tTG Iga test soon and I want to give it my best shot. I now have lots of evidence that going gluten free again is my best option.

nora-n Rookie

Actually, a few experts have banded together and formed some loose association or whatever on the topic of gluten sensitivity.

I think it is this site:

Open Original Shared Link

Open Original Shared Link

and some doctors have their own websites, like Dr. Ford, Dr. Lewey,

and some others have other websites: Open Original Shared Link

and there should be some more too.

Reminds me, I should make a list and put them in my google bookmarks.

      Raising you vitamin D will increase absorption of calcium automatically without supplementation of calcium.  A high PTH can be caused by low D causing poor calcium absorption; not insuffient calcium intake.  With low D your body is not absorbing calcium from your food so it steals it from your bones.  Heart has priority over bone. I've been taking 10,000 IU D3 a day since 2015.  My doctor says to continue. To fix my lactose intolerance, lots of lactobacillus from yogurts, and brine fermented pickles and saurkraut and olives.  We lose much of our ability to make lactase endogenosly with maturity but a healthy colony of lactobacillus in our gut excretes lactase in exchange for room and board. The milk protein in grass fed milk does not bother me. It tastes like the milk I grew up on.  If I drink commercial milk I get heartburn at night. Some experts estimate that 90% of us do not eat Adequite Intake of choline.  Beef and eggs are the principle source. Iodine deficiency is a growing concern.  I take 600 mcg a day of Liquid Iodine.  It and NAC have accelerated my healing all over.  Virtually blind in my right eye after starting antihypertensive medication and vision is slowly coming back.  I had to cut out starches because they drove my glucose up into the 200+ range.  I replaced them with Red Bull for the glucose intake with the vitamins, minerals and Taurine needed to process through the mitochodria Krebs Cycle to create ATP.  Went from A1c 13 down to 7.9.  Work in progress. Also take B1,B2,B3,B5,B6. Liquid Iodine, Phosphatidyl Choline, Q10, Selenium, D and DHEA.     Choline supplemented as phosphatidylcholine decreases fasting and postmethionine-loading plasma homocysteine concentrations in healthy men +

      @catnapt, Wheat germ has very little gluten in it.  Gluten is  the carbohydrate storage protein, what the flour is made from, the fluffy part.  Just like with beans, there's the baby plant that will germinate  ("germ"-inate) if sprouted, and the bean part is the carbohydrate storage protein.   Wheat germ is the baby plant inside a kernel of wheat, and bran is the protective covering of the kernel.   Little to no gluten there.   Large amounts of lectins are in wheat germ and can cause digestive upsets, but not enough Gluten to provoke antibody production in the small intestines. Luckily you still have time to do a proper gluten challenge (10 grams of gluten per day for a minimum of two weeks) before your next appointment when you can be retested.

      Hello, @asaT, I'm curious to know whether you are taking other B vitamins like Thiamine B1 and Niacin B3.  Malabsorption in Celiac disease affects all the water soluble B vitamins and Vitamin C.  Thiamine and Niacin are required to produce energy for all the homocysteine lowering reactions provided by Folate, Cobalamine and Pyridoxine.   Weight gain with a voracious appetite is something I experienced while malnourished.  It's symptomatic of Thiamine B1 deficiency.   Conversely, some people with thiamine deficiency lose their appetite altogether, and suffer from anorexia.  At different periods on my lifelong journey, I suffered this, too.   When the body doesn't have sufficient thiamine to turn food, especially carbohydrates, into energy (for growth and repair), the body rations what little thiamine it has available, and turns the carbs into fat, and stores it mostly in the abdomen.  Consuming a high carbohydrate diet requires additional thiamine to process the carbs into energy.  Simple carbohydrates (sugar, white rice, etc.) don't contain thiamine, so the body easily depletes its stores of Thiamine processing the carbs into fat.  The digestive system communicates with the brain to keep eating in order to consume more thiamine and other nutrients it's not absorbing.   One can have a subclinical thiamine insufficiency for years.  A twenty percent increase in dietary thiamine causes an eighty percent increase in brain function, so the symptoms can wax and wane mysteriously.  Symptoms of Thiamine insufficiency include stunted growth, chronic fatigue, and Gastrointestinal Beriberi (diarrhea, abdominal pain), heart attack, Alzheimer's, stroke, and cancer.   Thiamine improves bone turnover.  Thiamine insufficiency can also affect the thyroid.  The thyroid is important in bone metabolism.  The thyroid also influences hormones, like estrogen and progesterone, and menopause.  Vitamin D, at optimal levels, can act as a hormone and can influence the thyroid, as well as being important to bone health, and regulating the immune system.  Vitamin A is important to bone health, too, and is necessary for intestinal health, as well.   I don't do dairy because I react to Casein, the protein in dairy that resembles gluten and causes a reaction the same as if I'd been exposed to gluten, including high tTg IgA.  I found adding mineral water containing calcium and other minerals helpful in increasing my calcium intake.   Malabsorption of Celiac affects all the vitamins and minerals.  I do hope you'll talk to your doctor and dietician about supplementing all eight B vitamins and the four fat soluble vitamins because they all work together interconnectedly.

      Hi Jane: You may want to try the D3 I now take. I have reactions to fillers and many additives. Sports Research, it is based in the USA and I have had no bad reactions with this brand. The D3 does have coconut oil but it is non GMO, it is Gluten free, Soy free, Soybean free and Safflower oil free.  I have a cupboard full of supplements that did not agree with me -  I just keep trying and have finally settled on Sports Research. I take NAKA Women's Multi full spectrum, and have not felt sick after taking 2 capsules per day -  it is a Canadian company. I buy both from Amazon. I wish you well in your searching, I know how discouraging it all is. Florence.

      highly unlikely  NOTHING and I mean NOTHING else has ever caused me these kinds of symptoms I have no problem with dates, they are a large part of my diet In fact, I eat a very high fiber, very high vegetable and bean diet and have for many years now. It's considered a whole foods plant based or plant forward diet (I do now eat some lean ground turkey but not much) I was off dairy for years but recently had to add back plain yogurt to meet calcium needs that I am not allowed to get from supplements (I have not had any problem with the yogurt)   I eat almost no processed foods. I don't eat out. almost everything I eat, I cook myself I am going to keep a food diary but to be honest, I already know that it's wheat products and also barley that are the problem, which is why I gradually stopped eating and buying them. When I was eating them, like back in early 2024, when I was in the middle of moving and ate out (always had bread or toast or rolls or a sub or pizza) I felt terrible but at that time was so busy and exhausted that I never stopped to think it was the food. Once I was in my new place, I continued to have bread from time to time and had such horrible joint pain that I was preparing for 2 total knee replacements as well as one hip! The surgery could not go forward as I was (and still am) actively losing calcium from my bones. That problem has yet to be properly diagnosed and treated   anyway over time I realized that I felt better when I stopped eating bread. Back at least 3 yrs ago I noticed that regular pasta made me sick so I switched to brown rice pasta and even though it costs a lot more, I really like it.   so gradually I just stopped buying and eating foods with gluten. I stopped getting raisin bran when I was constipated because it made me bloated and it didn't help the constipation any more (used to be a sure bet that it would in the past)   I made cookies and brownies using beans and rolled oats and dates and tahini and I LOVE them and have zero issues eating those I eat 1 or more cans of beans per day easily can eat a pound of broccoli - no problem! Brussels sprouts the same thing.   so yeh it's bread and related foods that are clearly the problem  there is zero doubt in my mind
