Totally Confused On Genetic Test Results- Please Help?

Rate this topic

Recommended Posts

Hi,

I'm in the middle of a horrifyingly bad gluten challenge in preparation for my biopsy, etc., so please excuse any confused-sounding bits of this.

Before subjecting me to a gluten challenge, I had the genetic testing done. I don't entirely understand the results, but the gist is that I'm positive for one of the types:

HLA-DQ2 (DQA*05/DQB1*02) - Positive

HLA DQ8 (DQA*03/DQB1*0302) - Negative

HLA-DQA1* - 02

HLA-DQA1* - 05

HLA-DQB1* - 0201

HLA-DQB1* - 0202

If anyone out there actually understands this, I would really appreciate more insight.

The real confusion is coming from my parents. My dad also demonstrates symptoms similar to mine. The cause of my symptoms HAS been diagnosed as EITHER celiac or non-celiac gluten intolerance.

However, when my dad went in to get tested, too, they had him also do the HLA test and he came back negative. (My mom is negative, too.) I wanted to know how it's possible for both my parents to be negative, but then I'm positive. Does anyone understand the genetic component better?

I'm trying to encourage my dad to pursue this because he's having some symptoms that are troubling (i.e. serious brain fog) and I would like to see if I can get him some help before it gets worse.

Hi lobbyart - Did your parents go through the same doctor/lab for testing that you went through? You seem to have 1 copy (alpha and beta chains) of DQ2.5 and 1 copy (alpha and beta chains) of DQ2.2. Each parent has the capacity to give you 1 copy. Since you have 2 copies, both of your parents have at least 1 copy of DQ2. They cannot skip generations! Somewhere along the line, I'd wonder about the validity of tests... and whether you could get your hands on the exact results of your parents' gene tests...?

Good luck, keep us posted!

Thank you so much, Laura. Those results were unreadable to me! I really appreciate your help on this. So that would make me homozygous for DQ2?

I wish they'd just give us plain english... :)

Yes, you are homozygous for DQ2.

To be honest, I don't think many doctors know how to read the results, either. :ph34r: For the ones that do know how, I think it makes them feel good to be able to read the jargon... :lol:

    • Apologies for my over-reaction.  As the shampoo exposure was only for a couple week or so, I doubt any lab tests would have indicated exposure. Unfortunately, since I didn't have the antibodies, I can only rely on my symptoms to tell me if I've been exposed. I'm fortunate enough that eliminating gluten (and dairy) from my diet completely fixed my problems. I have had no lingering systems, and now that I have been gluten free for a while, when I do get gluten I have a very clear reaction (and a distinct reaction to dairy) that follows a fairly predictable timeline. This has accidentally been tested a couple of times. For example, early on before I was better at reading labels I grabbed some cookies at the grocery store that I thought were gluten free (the company produces both a normal and gluten-free version, and this was before I learned to avoid shared facilities). I had grabbed the wrong bag but I didn't figure it out until about a week of feeling crappy had passed and I went searching for a culprit. Things like this have happened a couple of times, where I accidentally did a blinded experiment on myself. The symptoms are consistent, and resolve once I remove the offending item. So when I recognized my symptoms as the result of gluten, I went looking for a culprit and I found the shampoo and conditioner. I removed them and then I got better.  My problems are largely systemic. I wouldn't be surprised if I don't actually have celiac but some other immune mediated reaction that hasn't been defined, but calling it celiac is the best way to get people to take my needs seriously (which I'm sure you understand). Unfortunately, my problems don't seem to fit into any particular diagnostic bucket, so I've learned not to rely on the official medical terms and just go with what works. I'm lucky to have had doctors who think the same way, else they might have told me that I didn't need to go gluten free once I failed to show clear-cut celiac. Maybe I'm pre-celiac, maybe it's the much maligned NCGS, or it's all related to leaky gut (I am eagerly awaiting the FDA approval of larazotide so that I can get a doctor to give me some, I think it might do me a lot of good). All I know is that when I went gluten and dairy free it literally changed my life.  In general it seems that gluten exposure causes a generalized inflammatory response. I get some inflammation in my gut that manifests as reflux, acid indigestion (what I call "fake hunger"), and a little bit of urgency and unpredictability with regards to bathroom needs, but if that were the only problem, I think I could live with it. I also get headaches, brain fog, my depression/anxiety gets triggered to a scary degree, arthritis, muscle aches, and then, the clincher, muscles spasms in my upper back and neck that have been known to lay me out for a couple of days while I wait for the muscle relaxants to help me heal. The muscle spasms, arthritis and brain fog are the most recognizable and are usually what cue me in that I got glutened, especially the spasms.  Again, sorry for being oversensitive. I should have known better, since this is such a supportive community.  
    • I appreciate your point. However, constancy of my celiac symptoms indicates that I have had the disease for at least three years - while I have never experienced any food allergies in that time. Although I will keep an eye on any emerging allergies, I believe my current fatigue is due to nutritional deficiency, because the only exogenous change in my life style has been the transition to gluten free diet.   Yes, I certainly need to keep a food diary. Thanks again for the advice.
    • In many cases no.....I consume heavy magnesium foods like pumpkin seeds, cocoa nibs etc....and still need 2-3x the dose of magnesium recommendations. Going on more of what poster boy said. You dose magnesium to tolerance with citrate like Natural Vitality Calm you start off small partial doses and slow ramp up....it can hit you hard causing gas and D if you go to quick into it. You dose citrate to tolerance meaning you slowly up your dose til you get loose stools...then back down a bit. You should have vivid dreams with a good dosing....also if it becomes to harsh or you can not handle citrate there is Doctors Best Glycinate...it does not have the gut effects at all...but the dreams and how much it makes you relax is more more felt.   ...with this disease you can have a food intolerance or allergy crop up out of the blue....like no where. You have a autoimmune disease....celiac it effects your immune system and can make it really wonky. Like it seems to always be on guard like a sleep deprived sentry on stim packs...jumps at everything and shoots it. If you get sick, eat something odd or harsh you system might red flag it as a issue for awhile and go bonkers....keep a food diary and try a food rotation in the mean time...OH as a example to this, I was fine with chia seeds last week...I got a cold over the weekend....same bag, same brand same way....withing 30mins I now puke if I eat them...new intolerance.....I also am finding jalapenos/paprika making it sleepy tired....so I am removing them both for a few months from my diet and changing to other sources for fats/fiber and vitamin A/C til I get over that issue.....these things just happen. https://www.mindbodygreen.com/articles/are-food-sensitivities-for-life
    • Hi Isabel, Your body needs nutrients to grow.  Nutrients not absorbed well when we have celiac disease damage in our guts.   But, if you do a good job of avoiding gluten, the gut damage should heal and you will be able to absorb nutrients again. The thing to remember is celiac disease is an immune system reaction.  Immune reactions are very sensitive and just a tiny amount of gluten can get them going.   And they can last for months.  So it;s very important to avoid all gluten all the time, to keep the immune reaction down.  Keeping the immune reaction down keeps the damage down, and the healing can keep up. You may start to grow more if you can absorb nutrients better.  Some extra vitamin pills might be a good idea.  Your doctor should know.  
    • Thank you Gail for your response. Of course one should be mindful of the possibility of food allergies but I don't think that's the case with my current situations. Save for gluten containing product, everything I eat now I used to eat before with no reaction whatsoever. I think my issue is more likely to be deficiency in minerals and such.
