Genetics Question?

Okay guys, I got my Enterolab results yesterday. I ordered Enterolab before I could get into the GI doctor, so I was desperate. My GI doctor did an endoscopy last week, which showed damage in my small intestines (full results aren't here yet) and that was after 8 weeks of gluten-free diet. My GI said there were probably enough goodies to suggest Celiac. Here's the Enterolab:

A) Gluten Sensitivity Stool and Gene Panel Complete *Best test/best value

Fecal Anti-gliadin IgA 19 Units (Normal Range is less than 10 Units)

Fecal Anti-tissue Transglutaminase IgA 7 Units (Normal Range is less than 10 Units)

Quantitative Microscopic Fecal Fat Score 900 Units (Normal Range is less than 300 Units)

Fecal Anti-casein (cow

I'm new here too, so I can't comment on many of your questions, but regarding dairy, you are probably lactose intolerant due to the intestinal damage, you may not necessarily be sensitive to casein, the protein in milk. If you do OK with yogurt and lactose-free milk, it's just lactose intolerance and it may go away after you heal your gut. I've been gluten-free for 2 weeks, and after feeling GREAT at first, i'm now suffering from extreme mental fogginess and sleepiness. I suspect it's gluten withdrawl. The diarrhea initially improved a bit, but now it seems to be getting worse. I hope this turns around soon!

That high fecal fat score means you have a lot of villi damage.

The Enterolab tests do not count much with ordinary doctors and are only designed to be so sensitive that they pick up early gluten and other issues.

ttg is a marker of gut damage and if you are gluten free the damage of course is reversing so that the ttg levels go down.

Being off gluten makes it harder to get a diagnosis, but you have the Enterolab tests with very high fecal fat scores and the antibodies to confirm there is an issue.

Maintream testing is designed to not to pick up any false positives, it looks like they are very afraid of that. With false positives they also mean symptoms but nor a lot of gut damage upon endoscopy.

It took me 7 months totally off gluten and I woke up one morninge and I was not so awfully fatigued.

Have you gotten any b-12 ? It is said to hel cell regeneration or things like that. Some even think taking b-12 can be the cause of positive blood tests and negative biopsies, that it causes false negatives. Just a theory. (steroids do that)

Your endoscopy and feeling better off gluten is enough for you to be reasonably sure some degree of gluten intolerance is at least part of your problem. Your genetic results with DQ2 are consistent with celiac/gluten intolerance. I assume your GI took a biopsy. Once you get those results you'll know a little more.

Given the fact that your doc said he saw visible damage after EIGHT WEEKS of being on a gluten free diet, and even without the lab work being back yet, combined with the low scores, would suggest to me that you need to have him run a total serum IgA. You may be IgA deficient which would make any IgA based antigen tests worthless. This would also mean you would have no easy way other than dietary response or repeat biopsies to verify your compliance with a gluten free diet. So it would be good to know if you are IgA deficient.

Hi Zizzle,

If someone is IgA deficient you can't use IgA response to Casein or any other IgA measurements as a guide. See my response above.

Thanks for the tips. I'm definitely on B12, as well as a boatload of other fun stuff. I'm hoping that once my absorption gets better I won't feel so tired :)

Hi Skylark, I was hoping you would comment on the genetics portion. You are very informative on genetics!! Yes, my GI took biopsies. My Enterolab results said, "having one celiac gene and one gluten sensitive gene, means that each of your parents, and all of your children will possess at least one copy of a gluten sensitive gene." So, I got it from both sides? Gene analysis was performed by the American Red Cross (strange, I didn't know they did that type of stuff).

Hi Korwyn, I'm pretty sure my GI got a total serum from me last week. Would Celiac Plus cover that? My doctor sent me to a specialty lab within a hospital that would draw & handle the blood properly to send to Prometheus. I hope it was the right panels? It should be, I think it was 11 vials. My endo drew blood a few months back with a negative Celiac diagnosis, but my new GI thinks he can pull enough info from both to get the answers he's looking for, plus the biopsy.

Glad to be helpful. :)

I disagree a little with the way Enterolab calls genes "gluten sensitive". Just about any genotype can end up biopsy confirmed celiac; however, some genotypes carry much higher risk. 99% of people with celiac disease are either DQ2 or DQ8 with 80-90% of celiacs having a form called DQ2.5. Enterolab labels everything but DQ4 as potentially gluten-sensitive, without explaining that genes other than DQ2 or DQ8 are actually fairly low risk, or that DQ2.5 is higher risk.

Your 0201 allele is high risk. It is usually inherited as part of DQ2.5 (Enterolab didn't test for DQA1 to be sure) so chances are better than 99% that you are DQ2.5. This means that at least one of your parents is also at risk for celiac and your children would have a 50% chance of getting the gene from you. In a study where people were tested for HLA-DQ and anti-endomysial antibodies, 9% of the people with one copy of DQ2.5 had celiac serology so it would be wise for your parents to at least get a blood test.

Your 0603 allele, often called DQ6 is very low risk. The parent who has that allele, or a child that gets it would not be at any particular risk for celiac disease or gluten sensitivity from that allele. It doesn't rule out celiac, but you would only worry about it if they had a lot of other symptoms.

Thanks Skylark! That's exactly the explanation I was needing.

      Diagnosed celiac for 1-2 months ago and everything makes me bloated.

      By Beverage · Posted

      I had a very rough month after diagnosis. No exaggeration, lost so much inflammatory weight, I looked like a bag of bones, underneath i had been literally starving to death. I did start feeling noticeably better after a month of very strict control of my kitchen and home. What are you eating for breakfast and lunch? I ignored my doc and ate oats, yes they were gluten free, but some brands are at the higher end of gluten free. Lots of celics can eat Bob's Red Mill gluten-free oats, but not me. I can now eat them, but they have to be grown and processed according to the "purity protocol" methods. I mail order them, Montana Gluten-Free brand. A food and symptoms and activities log can be helpful in tracking down issues. You might be totally aware, but I have to mention about the risk of airborne gluten. As the doc that diagnosed me warned . . Remember eyes, ears, nose, and mouth all lead to your stomach and intestines.  Are you getting any cross contamination? Airborne gluten? Any pets eating gluten (they eat it, lick themselves, you pet them...)? Any house remodeling? We live in an older home, always fixing something. I've gotten glutened from the dust from cutting into plaster walls, possibly also plywood (glues). The suggestions by many here on vitamin supplements also really helped me. I had some lingering allergies and asthma, which are now 99% gone. I was taking Albuterol inhaler every hour just to breathe, but thiamine in form of benfotiamine kicked that down to 1-2 times a day within a few days of starting it. Also, since cutting out inflammatory seed oils (canola, sunflower, grapeseed, etc) and cooking with real olive oil, avocado oil, ghee, and coconut oil, I have noticed even greater improvement overall and haven't used the inhaler in months! It takes time to weed out everything in your life that contains gluten, and it takes awhile to heal and rebuild your health. At first it's mentally exhausting, overwhelming, even obsessive, but it gets better and second nature.

      Protein or fat?

      By Jsingh · Posted

      Hi,  I care for my seven year old daughter with Celiac. After watching her for months, I have figured out that she has problem with two kinds of fats- animal fat and cooking oils. It basically makes her intestine sore enough that she feels spasms when she is upset. It only happens on days when she has eaten more fat than her usual every day diet. (Her usual diet has chia seeds, flaxseeds, and avocado/ pumpkin seeds for fat and an occasional chicken breast.) I stopped using cooking oils last year, and when I reintroduced eggs and dairy, both of which I had held off for a few months thinking it was an issue of the protein like some Celiac patients habe mentioned to be the case, she has reacted in the same fashion as she does with excess fats. So now I wonder if her reaction to dairy and eggs is not really because of protein but fat.   I don't really have a question, just wondering if anyone finds this familiar and if it gets better with time.  Thank you.

      High Cost of Gluten-Free Foods

      By Chanda Richard · Posted

      Hello, My name is Chanda and you are not the only one that gose through the same things. I have found that what's easiest for me is finding a few meals each week that last. I have such severe reactions to gluten that it shuts my entire body down. I struggle everyday with i can't eat enough it feels like, when I eat more I lose more weight. Make sure that you look at medication, vitamins and shampoo and conditioner also. They have different things that are less expensive at Walmart.

      Frequent nausea after gluten-free diet

      By petitojou · Posted

      Thank you so much! I saw some tips around the forum to make a food diary and now that I know that the community also struggles with corn, egg and soy, the puzzle pieces came together! Just yesterday I tried eating eggs and yes, he’s guilty and charged. Those there are my 3 combo nausea troublemakers. I’m going to adjust my diet ☺️ Also thank you for the information about MCAS! I’m from South America and little it’s talked about it in here. It’s honestly such a game changer now for treatment and recovery. I know I’m free from SIBO and Candida since I’ve been tested for it, but I’m still going to make a endoscopy to test for H. Pylori and Eosinophilic esophagitis (EoE). Thank you again!! Have a blessed weekend 🤍

      Unusual bright yellow but odourless discharge

      By knitty kitty · Posted

      Yes, I, too, have osteoporosis from years of malabsorption, too.  Thiamine and magnesium are what keep the calcium in place in the bones.  If one is low in magnesium, boron, selenium, zinc, copper, and other trace minerals, ones bone heath can suffer.  We need more than just calcium and Vitamin D for strong bones.  Riboflavin B 2, Folate B 9 and Pyridoxine B 6 also contribute to bone formation and strength.   Have you had your thyroid checked?  The thyroid is important to bone health as well.  The thyroid uses lots of thiamine, so a poorly functioning thyroid will affect bone heath.
