Genetic test--anyone understand this?

We decided to do a genetic test on our older son and these are the results:

DQ ALPHA 1 02:01, 04:01

DQ BETA 1 02:02, 04:02

Celiac gene pairs: equivocal

The dr will call next week, but I was researching and trying to see what this means this weekend (just curious).  I haven't seen a 04:01 or 04:02 in anything I've read...anyone know what all this means?

Okay, the dr just wrote a note on the test.  

"Celiac genes not present.
Not likely that he has celiac disease.
Most likely a gluten intolerance."  

 But the test says equivocal.  ?  

Confused.  

Background, he had a weak positive antibody test.  When the pediatrician called with the results, she didn't tell us to stay on gluten, so, we took him off gluten.  He has been off gluten for over a month.  His GI symptoms cleared up and he started gaining weight again for the first time in over a year.  Plus, his nutrition blood tests have improved. But, he still hasn't started getting taller (height growth had slowed down a whole lot).   

I have 1st degree relatives with celiac disease.  I tested negative for antibody test (wasn't a complete panel), but in spite of that, I react strongly to gluten and have felt much better since I stopped eating it. So I have been thinking maybe I have celiac disease like them.

  I'm really worried b/c his growth has slowed so much (short and thin).  If this isn't celiac disease like we thought, then what on earth is going on? 

 Guess we could try a gluten challenge and do an endoscopy...oh that sounds like torture.  Any thoughts?

I know very little about gene testing as I was diagnosed without it.  So, I am not even going to comment on it. However, I was sure my 19 year old niece had celiac disease or the family non-functioning gallbladder curse.  She tested negative to the complete panel, had a HIDA scan, endoscopy and a colonoscopy.  All were negative.  She is tiny.  Short and very thin too.  She has been having "attacks" for the past five years.  Then  her new GI ordered a pill cam.  She was diagnosed with Crohn's just last week.  She does not even present with the typical symptoms.  The camera caught damage in the small intestine just prior to going into the colon.  

I am not saying that your child has Crohn's.  Autoimmune runs rampant in our family (RA, lupus, celiac disease, Thyroiditis,  etc) But no one had been diagnosed with Crohn's.  It was not even on our radar.  My niece does know that she still can develop celiac disease at anytime.  Anyone in my family can.  

Your testing?  Please ask for the complete panel.  I always test negative to the TTG tests (even follow-up).  I test positive only to the DGP IGA yet my biopsy revealed a Marsh Stage IIIB.  My symptom was anemia.  No tummy issues.  Doctors blamed it on my anemia on Thalassemia (genetic anemia) and being a woman.  When it became really bad.....menopause.  See how it it can be to overlook a diagnosis?  

My family?  Yep, still negative because most have had the screening TTG only.  A GI (their insurance) is only authorized  to order a complete panel.  What a hassle!!!!!  Just my niece and my kid had the complete panel.

Oh, as far as improving on the gluten-free diet?  It might not just be gluten free that is helpings him,  but maybe he is eating healthier (whole foods, etc) ?

If the doctor thinks it is a gluten intolerance, and some of his symptoms cleared up when you eliminated gluten from his diet, then that is probably what the problem is.  As for the growth, it's only been a month.  His body is working very hard to heal whatever damage has been caused up to this point.  All of his energy is going toward cellular repair and regeneration.  These things take time.  Once that work has been done, his body can focus on skeletal growth.  Talk with the pediatrician about these concerns too.  I'm sure she will be able to reassure you.  If it makes you feel better, take him in for extra well child visits until his growth rate improves.

Thank you for your responses.  

 

Cycling lady, we had a pretty good diet to begin with.  Avoided processed foods and ate lots of whole foods, so I think it is probably the gluten free diet that is helping him. I did do some reading and learned a bit about his gene-type.  There are celiacs with this gene, it is just rare.  Looks like he might just be a rare case.  Going to follow-up with the dr to find out more.  Appreciate your help and advice.  It is good to remember that it will take some time to heal...I'm definitely a bit impatient to see him fully recovered! :-)

There is still much to be learned about genetics when it comes to celiac. If you can do bring a peer-reviewed article or two with you when you go back to the doctor for follow-up. Not all doctors are up on the newest research and it may help with your son and others in the diagnosis process.

I hope your son heals quickly.

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      Terrible Neurological Symptoms

      By knitty kitty · Posted

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/
