Anyone Able To Interpret The Genetic Testing

Today I got my genetic testing back.

It shows category #4 DQ2 heterozygous. Related risk high. Though I see there is a Very High and Extremely High category, in addition to Moderate, Low, and Extremely Low.

Specifically, DQ2.5 (HLA DQA1*05:DQB1*201) are listed.

The only blood work that came back positive was the Anti-gliadin IGA, which was 24 on a range from 0-15.

Biopsy was done a few months before they were really looking for celiac so I don't know how many biopsies were taken, but they didn't show anything abnormal.

Yes, I have many symtoms but I also have sjogren's syndrome.

Have been trying to be gluten free but am still trying to work out things like shampoos, detergents, lotions, and the like. It will probably take awhile to get thing right.

I am not feeling at all better after a few weeks gluten free. In fact, I'd say that it feels like everything I eat makes me sick and I continue to lose weight.

Have pain in my arms and tingling in my face, legs, and feet.

Thoughts?

This is the most common celiac gene, also nicknamed HLA DQ2. (HLA DQ2,5)

You have only one copy of the DQ2,5 gene.

If you call the lab, they might have the result of the other gene (but it would not change things, since you already have the typical celiac gene)

Those genes are just about the risk, they do not mean you are celiac. Lots of people have HLA DQ2 and will never develop celiac disease.

The positive antigliadin IgA probably means it is early or patchy celiac, and with patchy celiac they might find a spot with celiac, or not, when taking biopsies.

Did they do the more specific deaminated gliadin test that many are getting now? It is much better at catching early celiac.

They did 4 different tests on blood work before the gene test. Here's what came back.

IMMUNOGLOBULIN A-SERUM normal range

GLIADIN ANTIBODY, IGA 24 (Abn: H) 0 - 15 is normal

GLIADIN ANTIBODY, IGG normal range

TISSUE TRANSGLUTAMINASE-A normal range

Annotation:

GLIADIN ANTIBODY, IGA

strict gluten free diet.

As stated, they would not do another endoscopy because they had done one 3 months earlier while checking for something else. From what I read on the biopsy report, lab only received 2 samples from the small intestines, which looked normal.

The only thing shown in the endoscopy was inflammation of the stomach. Colonoscopy showed 3 small diverticula.

Nurse for GI doc says go gluten free, regular GP says this really doesn't mean anything. It's very important to me, of course. My son came back with the same blood work, with an even higher Gliadin Antibody, IGA of 36.

Take all this paperwork to a new GI that specializes in Celiac disease.

There recently was a study trying to find out why one area in the U.S. had half as many positive biopsies compared to the other half of the country, and the difference was how many samples were taken.

Now the area where they took 4 or more samples while doing endoscopy, had twice as many diagnosed with celiac compared to where they only took about 2 samples.

I guess they missed your celiac, as the most common form of celiac nowadays is patchy celiac.

Also, the antigliadin test is known to rise first, and then the ttg, in early celiac.

I would guess that if you continue eating gluten, and even increase the gluten intake, then you will get a positive ttg test, and positive biopsies, after a month or two.

Things can change in a matter of a month or two or three.

But maybe the very specific deaminated gliadin test would tell you more beforehand, as it is very specific for celiac. If it is negative, it probably would not help to do another endoscopy yet.

(here in Europe we often do a gluten challenge to get a diagnosis, if the test results are dubious)

      Son's legs shaking

      Thank you! That's helpful. My kids eat very little processed food. Tons of fruit, vegetables, cheese, eggs and occasional red meat. We do a lot of rice and bean bowls, stir fry, etc. Do you think with all the fruits and vegetables they need a vitamin supplement? I feel like their diet is pretty healthy and balanced with very limited processed food....

      @lizzie42, You're being a good mom, seeking answers for your son. Cheers! Subclinical thiamine deficiency commonly occurs with anemia. An outright Thiamine deficiency can be precipitated by the consumption of a high carbohydrate meal.

      Bob red mill gluten free oats

      Oats naturally contain a protein called avenin, which is similar to the gluten proteins found in wheat, barley, and rye. While avenin is generally considered safe for most people with celiac disease, some individuals, around 5-10% of celiacs, may also have sensitivity to avenin, leading to symptoms similar to gluten exposure. You may fall into this...

      High TTG-IgG and Normal TTG-IgA

      @SamAlvi, It's common with anemia to have a lower tTg IgA antibodies than DGP IgG ones, but your high DGP IgG scores still point to Celiac disease. Since a gluten challenge would pose further health damage, you may want to ask for a DNA test to see if you have any of the commonly known genes for Celiac disease. Though having the genes for Celiac...

      Thank you! That's helpful. My kids eat very little processed food. Tons of fruit, vegetables, cheese, eggs and occasional red meat. We do a lot of rice and bean bowls, stir fry, etc.  Do you think with all the fruits and vegetables they need a vitamin supplement? I feel like their diet is pretty healthy and balanced with very limited processed food. The only processed food they eat regularly is a bowl of Cheerios here and there.  Could shaking legs be a symptom of just a one-time gluten exposure? I guess there's no way to know for sure if they're getting absolutely zero exposure because they do go to school a couple times a week. We do homeschool but my son does a shared school 2x a week and my daughter does a morning Pre-K 3 x a week.  At home our entire house is strictly gluten free and it is extremely rare for us to eat out. If we eat at someone else's house I usually just bring their food. When we have play dates we bring all the snacks, etc. I try to be really careful since they're still growing. They also, of course, catch kids viruses all the time so I  want to make sure I know whether they're just sick or they've had gluten. It can be pretty confusing when they're pretty young to even be explaining their symptoms!

      @lizzie42, You're being a good mom, seeking answers for your son.  Cheers! Subclinical thiamine deficiency commonly occurs with anemia.  An outright Thiamine deficiency can be precipitated by the consumption of a high carbohydrate meal.   Symptoms of Thiamine deficiency include feeling shakey or wobbly in the legs, muscle weakness or cramps, as well as aggression and irritability, confusion, mood swings and behavior changes.  Thiamine is essential to the production of neurotransmitters like serotonin and dopamine which keep us calm and rational.   @Jsingh, histamine intolerance is also a symptom of Thiamine deficiency.  Thiamine is needed to prevent mast cells from releasing histamine at the slightest provocation as is seen in histamine intolerance.  Thiamine and the other B vitamins and Vitamin C are needed to clear histamine from the body.  Without sufficient thiamine and other B vitamins to clear it, the histamine builds up.  High histamine levels can change behavior, too.  High histamine levels are found in the brains of patients with schizophrenia.  Thiamine deficiency can also cause extreme hunger or conversely anorexia.   High carbohydrate meals can precipitate thiamine deficiency because additional thiamine is required to process carbohydrates for the body to use as fuel.  The more carbohydrates one eats daily, the more one needs additional thiamine above the RDA.  Thiamine is water soluble, safe and nontoxic even in high doses. Keep in mind that gluten-free processed foods like cookies and such are not required to be fortified and enriched with vitamins and minerals like their gluten containing counterparts are.  Limit processed gluten-free foods.  They are often full of empty calories and unhealthy saturated fats and additives, and are high in histamine or histamine release triggers.  It's time you bought your own vitamins to supplement what is not being absorbed due to malabsorption of Celiac disease.  Benfotiamine is a form of Thiamine that has been shown to improve intestinal health as well as brain function. Do talk to your doctors and dieticians about supplementing with the essential vitamins and minerals while your children are growing up gluten free.  Serve nutritionally dense foods.  Meats and liver are great sources of B vitamins and minerals. Hope this helps!  Keep us posted on your progress!

While avenin is generally considered safe for most people with celiac disease, some individuals, around 5-10% of celiacs, may also have sensitivity to avenin, leading to symptoms similar to gluten exposure. You may fall into this category, and eliminating them is the best way to figure this out. Some people substitute gluten-free quinoa flakes for oats if they want a hot cereal substitute. If you are interested in summaries of scientific publications on the topic of oats and celiac disease, we have an entire category dedicated to it which is here: https://www.celiac.com/celiac-disease/oats-and-celiac-disease-are-they-gluten-free/
