Need Help Interpreting Hla Results

Hi I am new here and I need some help. My 14 month old has been having problems with constipation since he was 8 months. He had a celiac panel ran but he doesn't produce IgA. We had the HLA testing done and he tested positive for DQ2. I understand that, but I am having trouble with some of the results. It was done throuh Labcorp.

Results:

DQ2 (DQA1 0501/0505, DQB1 02XX) POSITIVE

DQ8 (DQA 03XX, DQB1 0302)

Final Results:

DQA1*04:01, 05:01

DQB1*02:01,04:02

Does this mean he has 4 alleles of the DQ2 gene? If so that would mean he has 2 copies of the DQ2 gene, correct? I have a BS in Cell and Molecular biology so this isn't completely foreign to me, I'm just having some difficulty reading the results. We have a follow up with the GI next month and I want to be prepared.

Try Wiki, but i think he has DQ2.5 the most commonly associated with celiac.

Thank you frieze. I did figure it out. I think I just needed to take a break and look at it again. It does look like he has DQ2.5 and a DQ4 which the DQA1*0401, DQB1*0402 is associated with. He has been on a gluten free diet for a week now and I already see some improvement!

      Isolated DPG-Iga

      By trents · Posted

      So, I contacted Scott Adams, the author of that article and also the creator/admin of this website, and pointed out to him the need to clarify the information in the paragraph in question. He has now updated the paragraph and it is clear that the DGP-IGA does serve the purpose of circumventing the false negatives that IGA deficiencies can generate in the tTG-IGA antibody test.

      Lymph nodes

      By Soleihey · Posted

      Has anyone experimenced enlarged lymph nodes with celiac? Both in the neck and groin area. Imaging of both areas have said that lymph nodes are reactive in nature. However, they have been present for months and just wondering how long this may take to go down. Been gluten-free for about two months. Blood counts are normal.

      Hmm interesting I just assumed that any “IGA” tests including the DPG iga would be negative in a person who is IGA deficient but maybe that is not the case for the DPG test.

      If you were just diagnosed I can say that if you go 100% gluten-free should should see dramatic improvement of your symptoms over the next few months, but the hard part is to stay gluten-free. This article has some detailed information on how to be 100% gluten-free, so it may be helpful (be sure to also read the comments section.):
