Interpreting Genetic Test Results

Hi all. When I got the results from my genetic test I just skipped through to the conclusion since the numbers made no sense to me. But I know there are people here who are good at explaining them, so if anyone gets a chance I'd be really grateful.

The report (hoping the formatting works, I'm trying to keep it as laid out in the original) says:

===========================================

Methodology: HLA-DR and HLA-DQ genotyping by PCR-Sequence Specific Priming

HLA-DR ................12, 15

____DRB1.............12, 15

HLA-DQ ..................6,7

____HLA-DQA1 .......01, 05

____HLA-DQB1 .......0301/4/9/10/13/14/16,06

Conclusion: No genotype susceptibility for coeliac disease. The DQ2 and DQ8 antigens associated with increased risk of coeliac disease were not identified in this patient. In the absence of these antigens, coeliac disease is extremely unlikely.

============================================

Any thoughts?

well i dont know enough about genetics yet to know what the HLA-DR is associated with- you could google it to see what it is predisposed for (but dont worry yourself- having a certain gene doesnt mean u will have the disease).

and it looks like u have a DQ 6 and a DQ 7... they're not the "classic" Celiac genes.. but that doesnt mean you could not have Celiac or Gluten Intolerance. i know many research centers and universities in America say it is virtually impossible to have Celiac without a DQ2 or DQ8, but they ARE diagnosing Celiacs in Europe with additional DQ genes. and they're are plenty of members on here with different DQ genes that are COMPLETELY gluten intolerant- and possibly Celiac. so, basically, imho, i would say you are gluten sensitive at least- and you should listen to your body and try the diet.

whoa, didnt mean to blab so long :/

I am soooo glad I was firmly diagnosed celiac before any gene testing was done. I would be dead by now if I had continued eating gluten. Gene testing is a relatively new science and we are learning more every day. There are many more genes associated with celiac than just the two they look for. Don't let those results convince you to go back on gluten if the diet is helping you.

Thanks to both of you for the replies (and sorry I didn't say so before, posted then had no internet access for over a week!)

Interesting about the other DQ results. I'm very strictly gluten free and I won't go back to eating gluten again, but I find it all very interesting and I'm curious in particular about the neurological manifestations of gluten intolerance. There's so much to learn, it's a shame I'm not scientifically inclined enough to go off and study it for real :-)

      Implications of glutening after repairing villi

      By RMJ · Posted

      It will not undo all of the healing.  If it did, diagnosis of celiac disease would be much easier!  To have enough damage to see on an endoscopy requires several weeks of gluten ingestion.

      Implications of glutening after repairing villi

      By Jean Shifrin · Posted

      HI, I am new to this and am still in 'repair' mode, which I know will take time. But I'm wondering if anyone knows what happens if you ingest gluten after you have made a lot of progress in repairing your villi. Does anyone know if you just have a short-term issue? Or does an accidental ingestion of gluten derail all the work you've done and set you back to square one? Thanks.

      Is McDonald's Safe for Gluten-Free Orders?

      By Scott Adams · Posted

      Hydrolyzed wheat is wheat protein that has been broken down into smaller components through a chemical or enzymatic process called hydrolysis. This ingredient can be found in various products, including cosmetics, personal care items, and some food products. For people with celiac disease, hydrolyzed wheat is generally not safe to consume because it still contains gluten proteins, even in its broken-down form. Though hydrolysis reduces the size of these proteins, it doesn’t fully remove the components that trigger an autoimmune response in people with celiac disease. In food products, hydrolyzed wheat protein still poses a risk and should be avoided. With regard to the McDonald's French fries, the total amount of hydrolyzed wheat in the flavoring is small, and the amount that ends up in an order of fries is even smaller, and likely below 20ppm. McDonald’s states that the fries are gluten-free by ingredient and free from cross-contact with gluten-containing foods in their dedicated fryers. Third-party tests and statements by McDonald's confirm gluten levels are below the FDA threshold for gluten-free labeling (20 parts per million or less). So, while McDonald’s USA fries may be gluten-free based on testing, some people with celiac disease still approach them cautiously due to the past concerns and individual sensitivities.

      Is McDonald's Safe for Gluten-Free Orders?

      Here is an excerpt from this article: https://pmc.ncbi.nlm.nih.gov/articles/PMC82695:   Studies have shown that various peptidases of fungal, plant, animal, or bacterial origin are able to hydrolyze gluten into harmless peptides. According to SDS‐PAGE pattern, proteolytic enzymes hydrolyze gliadins (Heredia‐Sandoval et al., 2016; Scherf et al., 2018; Socha et al., 2019; Wei et al., 2018, 2020). Bacterial peptidase (Krishnareddy & Green, 2017), fungal peptidase (Koning et al., 2005), and prolyl endopeptidases (PEPs) (Amador et al., 2019; Janssen et al., 2015; Kerpes et al., 2016; Mamo & Assefa, 2018) thoroughly degrade gliadin fractions to decrease gluten concentration and influence celiac disease. Aspergillus niger derived PEP (AN‐PEP) were assessed in clinical cases for their impact on modifying immune responses to gluten in celiac patients (Lähdeaho et al., 2014). Guerdrum and Bamforth (2012) reported that PEP addition in brewing technology decreased the prolamin and all of the identified immunopathogenic gluten epitopes in beer production (Akeroyd et al., 2016). On the contrary, many of the recent investigations which employed enzyme‐linked immunosorbent assay (ELISA), mass spectrometry, and Western blot analysis reported that PEP did not thoroughly destroy the whole gluten proteins (Allred et al., 2017; Colgrave et al., 2017; Fiedler et al., 2018; Panda et al., 2015), which indicates that beers treated with PEP are not safe for celiac disease patients. Anecdotally, this excerpt supports what we hear from the celiac community on this forum with regard to "gluten free" hydrolyzed wheat products and that is that some still react to them while many don't.

      Anybody else have a similar experience...theories welcome as its something which i dont really understand.....

      By Scott Adams · Posted

      There aren't good studies that have been done on celiac disease remission, and I'm going from a distant memory of an older post here, but the longest remission that Dr. Stefano Guandalini from the University of Chicago Celiac Disease Center has witnessed was ~10 years, then the symptoms of celiac disease and the damage came back. The real issue though, is that you still could increase your risk of various related diseases and disorders by eating gluten, but again, celiac disease remission has not been studies enough to know what health risks you might face.
