    New Data Links RGS1 and IL12A Polymorphisms with Celiac Disease Risk

    Reviewed and edited by a celiac disease expert.

    Celiac.com 04/28/2016 - The development of celiac disease has been tied to polymorphisms in the regulator of G-protein signaling 1 (RGS1) and interleukin-12 A (IL12A) genes, but existing data are unclear and contradictory.

    Image: CC--Mehmet PinarciA research team recently set out to examine the associations of two single-nucleotide polymorphisms (SNPs) (rs2816316 in RGS1 and rs17810546 in IL12A) with celiac disease risk using meta-analysis.

    The research team included Cong-Cong Guo, Man Wang, Feng-Di Cao, Wei-Huang Huang, Di Xiao, Xing-Guang Ye, Mei-Ling Ou, Na Zhang, Bao-Huan Zhang, Yang Liu, Guang Yang, and Chun-Xia Jing.

    They are variously affiliate with the Department of Epidemiology, School of Medicine, Jinan University, Guangzhou, the Department of Stomatology of the First Affiliated Hospital of Jinan University, Guangzhou, the Department of Parasitology, School of Medicine, Jinan University, Guangzhou, and the Key Laboratory of Environmental Exposure and Health in Guangzhou, Jinan University, Guangzhou, China.

    The team began by searching PubMed and Web of Science for RGS1 rs2816316 and IL12A rs17810546 with celiac disease risk. They then estimated the odds ratio (OR) and 95% confidence interval (CI) of each SNP. They retrieved a total of seven studies, and used Stata 12.0 to perform statistical analyses.

    The available data indicated the minor allele C of rs2816316 was negatively associated with celiac disease (C vs. A: OR = 0.77, 95% CI = 0.74–0.80), while they did find a positive association for the minor allele G of rs17810546 (G vs. A: OR = 1.37, 95% CI = 1.31–1.43).

    They found that the co-dominant model of genotype effect confirmed the significant associations between RGS1 rs2816316/IL12A rs17810546 and celiac disease. They found no evidence of any publication bias.

    The team's meta-analysis indicates a connection between RGS1 and IL12A and celiac disease, and provides a strong support for deeper study into the roles of RGS1 and IL12A in the development of celiac disease.

    Celiac.com 02/18/2015 - It's well documented that HLA-DQ molecules play a role in the pathogenesis of celiac disease through the presentation of gluten peptides to CD4(+) T cells. The α- or β-chain sharing HLA molecules DQ2.5, DQ2.2, and DQ7.5 display different risks for the disease.
    Researchers have recently showed that T cells of DQ2.5 and DQ2.2 patients recognize distinct sets of gluten epitopes, which indicates that these two DQ2 variants select different peptides for display.
    To figure out if this is the case, the research team performed a comprehensive comparison of the endogenous self-peptides bound to HLA-DQ molecules of B-lymphoblastoid cell lines. The research team included E. Bergseng, S. Dørum, M. Arntzen, M. Nielsen, S. Nygård, S. Buus, G.A. de Souza, and L.M. Sollid. Th...

    Celiac.com 06/03/2015 - Although dietary gluten is the trigger for celiac disease, risk is strongly influenced by genetic variation in the major histocompatibility complex (MHC) region.
    A team of researchers recently set out to fine map the MHC association signal to identify additional celiac disease risk factors independent of the HLA-DQA1 and HLA-DQB1 alleles. The researchers included J. Gutierrez-Achury, A. Zhernakova, S.L. Pulit, G. Trynka, K.A. Hunt, J. Romanos, S. Raychaudhuri, D.A. van Heel, C. Wijmenga, and P.I. de Bakker.
    Their team fine mapped the MHC association signal looking for risk factors other than the HLA-DQA1 and HLA-DQB1 alleles, and the found five new associations that account for 18% of the genetic risk.
    Taking these new loci together with the 57 known non...

    Celiac.com 09/16/2015 - Autoimmune disease, such as type 1 diabetes, Crohn's disease, and juvenile idiopathic arthritis, affect about 7 to 10 percent of the population in the Western Hemisphere.
    Using genome-wide association studies (GWASs), researchers have identified hundreds of susceptibility genes, including shared associations across clinically distinct autoimmune diseases.
    A team of researchers recently conducted an inverse χ2 meta-analysis across ten pediatric-age-of-onset autoimmune diseases (pAIDs) in a case-control study including more than 6,035 cases and 10,718 shared population-based controls.
    The research team included Yun R Li, Jin Li, Sihai D Zhao, Jonathan P Bradfield, Frank D Mentch, S Melkorka Maggadottir, Cuiping Hou, Debra J Abrams, Diana Chang, Feng Gao,...

    Does a Long Noncoding RNA Influence Susceptibility to Celiac Disease?
    Celiac.com 04/11/2016 - Growing evidence suggests that long noncoding RNAs (lncRNAs) play an important role in gene expression, especially that which influences inflammation. For example, researchers recently found that one lncRNA, lnc13, suppresses inflammatory gene expression in macrophages by interacting with proteins that regulate chromatin accessibility.
    Reduced levels of lnc13 in intestinal tissue from individuals with celiac disease suggests that lnc13 might also play a role in the development of immune-mediated diseases. In a recent issue of Science, a research team reports on the identification and characterization of a lncRNA, lnc13, that harbors a celiac disease–associated haplotype block and represses expression of certain inflammatory genes under homeostatic conditions.<...>

      9 Year Old test results - help interpret

      Welcome to the forum, @Gill.brittany8, Yes, the bloodwork is confusing. One has to be eating a sufficient amount of gluten (10 grams/day, about 5-6 slices of bread) in order for the antibody level to get high enough to be measured in the bloodstream. If insufficient amounts of gluten are eaten, the the antibodies stay in the small intestines...

      Years of testing - no real answers

      The intestinal tract can be as long as twenty-two feet long, so intestinal damage may be out of the reach of endoscopy tools. Some people have had more success with capsule endoscopy, but this method cannot take biopsies.

      Sorry about that link. It was meant for a different post. Do consider taking high dose Vitamin D in order to get your level up to around 80 nm/l quickly. This is the level where Vitamin D can properly work like a hormone and can improve the immune system and lower inflammation. It makes a big difference. I took high dose Vitamin D and really...

      I don't buy it either. I think a much better explanation is that humans evolved with hookworms just as hookworms evolved with us. The immunoregulatory activities that hookworms conduct to avoid expulsion from the gut have over time been incorporated into how the gut immune system works as a whole, and without hookworms present the gut immune system is incomplete...
