Enterolabs, What Are My Gene Types? Malabsorption?

Midwifemama5

I have been reading through here and trying to figure out what my lab results mean, what my gene types are, but the more I read, the more confused I get...

Also, I have significant malabsorption according to their results, which would be in sync with my symptoms and other problems such as problems with B12 (I take shots, they just upped me) and other s/s of malabsorption.

Here is the results:

Antigliadian IgA 6

Antitissue Transglut. IgA 8

Fecal Fat Score 721 (normal <300 units)

Cows milk IgA 6

HLA-DQB1 Allele 1 0301

HLA-DQB1 Allele 2 0503

Serologic equivalent HLA-DQ 3,1 (subtype 7,5)

I don't understand what the alleles mean, what the significance of those number would be...and are my genes 3 and 1, or are they 7 and 5?

It says that I don't have the celiac genes, but the gluten sensitivity genes, but I'm interested to know what my gene types are.

And if I have normal results in everything else, why is my fecal fat score so high? Is it still possible that it's caused by gluten or is it more likely to be caused by something else?

I did have my blood IgA levels done through quest and they were normal, not low...

Thanks for the help! I hope to understand this more as I go, I looked at wikipedia, but that confused me more, and as a masters student in nursing, I don't hold much stock in wikipedia anyway...

Sorry I don't know why I have posted this twice...just wondering if anyone can help interpret these or point me to a good source (that's easy to understand)...

Hi!

Your HLA DQ genes are BOTH 3 and 1 and 7 and 5.

The reason is that DQ1 is split into 5 and 6, and 3 is split into 7,8 and 9.

Now your fecal fat score is very very high, and you have some other tests that can point to gluten intolerance.

Enterolab does not test for the alpha chains, and DQ7 often has 05* in hte alpha chain, and this is definitely a celiac gene.

You might want to consider another gene test with any lab that tests for alpha chains or half genes.

Usually doctors say cou cannot have celiac if you are not DQ2 or 8, but 6% of celiac have this half gene only, so the labs have started testing for alpha chains too. enterolab has not started to test for the alpha chins and they say it is to keep costs down.

They also only test for ttg and antigliadin IgA and if people have low total IgA then those tests will be low or negative. Your IgA might be lowish and that might cause falsely low test results.

In that case, tissue transglutaminase IgG and antigliadin IgG blood tests might be interesting.

Something is wrong.

Thanks, that does help...so when I see people post DQ3,1 in their siggies, is that what numbers I would put? I wouldn't include the other ones, the 7 and 5?

Also, what significance do the alleles have? Do they have any significance for gluten sensitivity?

I did have the blood work, it was normal...my iga levels were OK too, I believe 167 or similar...and I also have allergy skin testing and some blood testing, the only thing that showed up food wise was chocolate (ouch, I was moderate, and I definitely have seen less headaches since I stopped chocolate)...

Hi, the DQ7 and DQ5 would be most accurate in your case.

note that there is DQ7,5 and that does not mean that person ahs both 5 and 7, but it means that that person has the 05* alpha chain and you write it as DQ7,5.

So it would be DQ7 and DQ5.

Check out the charts at wikipedia, type in HLA DQ and there is a chart there with the beta chains (that is what was tested in your case) and the alpha chains that tend to come with them and what the corresponding DQ types are.

In the case of 0501 or 0505 alpha chains, they say that this chain contributes to the celaic risk, and not only the beta chains like 0302 for the DQ8 and 0201 for the DQ2. By the way, DQ2 has 0501 in the alpha chain.

DQ2,2 has 0202 in the beta chain but if the person also has DQ7,5, the 05* alpha chain forms DQ2,5, the celiac DQ, across the genes, and it is called trans DQ2,5.

That is a reason why they do the alpha chains too in many labs nowadays. Before they did not.

I did the other blood tests and they were all normal, my IGa was also normal. The IGG testing and the tTg were negative.

So not sure what to think. I know my kids will not adhere to a gluten free diet unless we get some results that are positive. My two daughters did the blood testing and they were all normal (although my 11yo had an IGA of 67, which is right at the low range for her age group so not sure if that causes the others to be low and her IGG was a bit high, normal is under 10 and hers was 17...)

I looked up more info on the Gene types 7 and 5, plus my alleles and haven't really found anything to point to celiac (although I did find the info about the possibility of a 1/2 gene on the 7 if I understand it correctly).

Since some of the info I am reading says it can take up to a year to see a difference after going gluten free, my family is very resistant to the change idea. It would be easier if we say immediate results, but we did do a month of gluten free before with really no improvement noted.

However, if anyone has more info about the gene types and alleles, that would be great. I find wikipedia hard to understand (and I'm in a masters program for nursing, so I would think it would make more sense)...and the info that enterolabs sent to me seems to be a form letter and doesn't make sense.

Are there others who are on here with those gene types, the 7 and 5? I would interested in learning more about your test results and diet results...

thanks!

There ahve been several postings here from people with 7&5.

And Dr. Lewey has had some patients with negative gene tests, and the patients have positive biopsies , and he did suspect half genes.

He said he had contacted the labs about that, that they probably were missing the half genes.

And, about half a year later people started to post here with both alpha and beta chains..

Enterolab never started to test for the alpha chains, nor did they tell people that if they had DQ2,2 and DQ7, this probably makes up DQ2,5 by trans.

(Even DQ2,2 alone is a bit celiac-predisposing)

About the DQ5: This is DQ1, amda up by DQ6 and 5. There are two forums out there about gluten sensitivity and anurological problems, and several there have DQ1.

Now if you google hadjivassiliou, you see that about 20% of his glutan atacia patients have DQ1, the rest DQ2 or 8.

I tried doing a search for DQ7 but I can't get the search engine to really narrow it down for me...

I'm confused how DQ5 is really DQ1? I'm sorry, I feel a bit stupid but I'm not understanding that? I had read about DQ1 causing neurological problems, but havent' see it explained about DQ5 being DQ1? Can you elaborate?

thanks for much for your help Nora, I really appreciate it.

I did find a study that linked DQ7 to milk intolerance, which is interesting....I've been trying to do some internet searches, but haven't found what I am looking for.

I will try to do another search for DQ7 and 5 on here and see if I can find anything...

      Food Allergies

      By Ginger38 · Posted

      So I recently had allergy testing for IGE antibodies in response to foods. My test results came back positive to corn, white potatoes, egg whites. Tomatoes, almonds and peanuts to name a few.  I have had obvious reactions to a few of these - particularly tomatoes and corn- both GI issues. I don’t really understand all this allergy versus celiac stuff. If the food allergies are mild do I have to avoid these foods entirely? I don’t know what I will eat if I can’t  have corn based gluten free products

      Bread choice for a newbie

      By Kris2093u4 · Posted

      Geography makes a difference.  I'm in the West and Trader Joe's gluten-free bread tastes great and is a better price than most gluten-free breads sold elsewhere in my area.

      7yo struggling!

      By JForman · Posted

      We have four children (7-14 yo), and our 7 year old was diagnosed with NCGS (though all Celiac labs were positive, her scope at 4 years old was negative so docs in the US won't call it celiac). We have started her on a Gluten Free diet after 3 years of major digestive issues and ruling out just about everything under the sun. Our home and kitchen and myself are all gluten-free. But I have not asked my husband/her dad or her other siblings to go completely gluten-free with us. They are at home, but not out of the home. This has led to situations when we are eating out where she has to consistently see others eating things she can't have and she has begun to say "Well, I can't have <fill in the blank>...stupid gluten."  How have you supported your gluten-free kiddos in the mental health space of this journey, especially young ones like her. I know it's hard for me as an adult sometimes to miss out, so I can't imagine being 7 and dealing with it! Any tips or ideas to help with this?

      My mo,ther married a bread making when I was 4

      By the time I was 5 I had my first auto0immune disorder, Migraine headaches, with auras to blind me, and vomiting, sensitivity to light and sound. I was 5 years old, and my stepfather would have pizza night, milling his own flour, making thick cheesy gluten pizza, that I would eat and the next day, I would have serious migraines, and my mother & stepfather did nothing about my medical problems. When I was 17 in my first year at college, I was diagnosed with my 2nd known auto-immune disorder, Meniere's disease. I was a elite athlete, a swimmer, and soccer player. And once again my parents didn't think anything of understanding why I had a disorder only older people get. Now after my mother passed from Alzheimer's disease she also suffered with living with gluten. She had a rash for 30 years that nobody could diagnose. She was itchy for 45 years total. My brother had a encapsulated virus explodes in his spleen and when this happened his entire intestines were covered with adhesions, scar tissue and he almost lost his life. He has 5 daughters, and when I finally was diagnosed after being pregnant and my body went into a cytokine storm, I lost my chance to have children, I ended up having Hashimoto's disease, Degenerative Disc disease, and my body started to shut down during my first trimester. I am 6ft tall and got down to 119lbs. My husband and I went to a special immunologist in Terrace, California. They took 17 vials of blood as we flew there for a day and returned home that evening. In 3 weeks, we had the answer, I have Celiac disease. Once this was known, only my father and husband made efforts to change their way of feeding me. At the family cabin, my stepfather & mother were more worried that I would ruin Thanksgiving Dinner. It wasn't until one of my cousins was diagnosed with Celiac disease. They finally looked into getting Gluten Free flour and taking measures to limit "gluten" in meals. He did nothing but ask for me to pay for my own food and wi-fi when I came to the cabin to stay after our house burned down. When he informed my mother, they proceeding to get into a physical fight and she ended up with a black eye. The is just more trauma for me. Sam had no interest in telling the truth about what he wanted. He lied to my mother that he had asked my husband if I could pay for "food" when he asked Geoffrey if I had money to pay for my wi-fi. My mother hates when he spends so much time on the computer so he lied and said I could pay for my own food. I will remind you I weighed 119lbs at this time. (At 6ft) that is a very sick looking person. Neither parent was worried about my weight, they just fought about how cheap my stepfather was. As my mother was diagnosed with Alzheimer's disease in 2014. He had her sign over the will to a trust and added his children. He had no testimonial capacity at the time, so she signed without proper papers. Making this Trust null and void. When I gave my brother my childhood home, my mother stated I would be getting an equal part of inheritance to the house on Race. It currently worth 2.0 million $. I got nothing, and my stepfather has since disowned me b/c of my claim and he knows that my mother would never have left it uneven between my biological brother and myself. She sat me and my husband down, as we lived at the Race Street house and treated and took care of it as our own. My brother took over b/c he was going through a horrific divorce and needed a home so he could get a better custody deal with his soon to be ex-wife who was a Assist DA for Denver. She used the girls against him, and he & I were the primary caregivers. We, Judd and I spent the most time with them pre the divorce. Once Judd moved into the house, he threw all of my mother, grandmother and my family heirlooms out to the Goodwill. Nobody told my mother about this as she was going through cancer treatment and had Alzheimer's disease in her mother and her sister. My stepfather and biological brother took advantage of this matter, as I called a "family council" that my brother just never could make it to at the last moment. All of the furnishing, kitchen ware, everything was in the house my brother just moved into. He had had 2 weddings, I chose to elope b/c my stepfather ruined my brother's first wedding by talking about his relationship with my brother in front of my dad and his entire family, insulting him and having my grandfather leave the ceremony. It was a disaster. My stepfather just plays dumb and blames my father for the slight. I was the only child not to have a wedding. So, my mother and stepfather never had to pay for a thing. My mother had had an agreement with my father he'd pay for college and all medical issues with their kids, myself and Judd. So truly my mother never had to pay for anything big for me in her entire life. I am looking for anyone that has had a similar story, where they grew up in a household that had a baker that regularly milled flour and ate gluten. What happened to you? DId you suffer from different auto-immune diseases b/c of living with a baker using "gluten" Please let me know. I have been looking into legal ways to get my stepfather to give me what my mother had promised, and he erased. Thank you for listening to my story. Jane Donnelly

      Blood results

      By trents · Posted

      Possibly gluten withdrawal. Lot's of info on the internet about it. Somewhat controversial but apparently gluten plugs into the same neuro sensors as opiates do and some people get a similar type withdrawal as they do when quitting opiates. Another issue is that gluten-free facsimile flours are not fortified with vitamins and minerals as is wheat flour (in the U.S. at least) so when the switch is made to gluten-free facsimile foods, especially if a lot of processed gluten-free foods are being used as substitutes, vitamin and mineral deficiencies can result. There is also the possibility that she has picked up a virus or some but that is totally unrelated to going gluten-free.
