    Fine Mapping MHC Region Adds New Info on Genetic Risk for Celiac Disease

    Reviewed and edited by a celiac disease expert.

    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.

    Photo: CC--Shawn AllenA 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-MHC loci, genetic variation can now explain up to 48% of celiac disease heritability.

    Nailing down exactly what genetic factors influence the heritability of celiac disease will help researchers to better understand the disease, and to develop better treatments and screening options.

    Celiac.com 06/26/2007 - The results of a study recently published in the online science journal Nature Genetics have revealed a previously unknown genetic risk factor for celiac disease. An international team of researchers set out to study the genetic causes of intestinal inflammatory disorders. When the study began, it was well known that individuals with celiac disease have specific tissue types that identify wheat proteins. Why healthy individuals with the same tissue type failed to develop celiac symptoms or celiac disease remained unknown, and was a key question the team set out to answer. The team was led David van Heel, Professor of Gastrointestinal Genetics at Queen Mary, University of London. The Human Genome Project and the Hap Map Project played key support roles in the...

    Celiac.com 08/17/2008 - Are you confused about genetic testing for celiac disease? Do you want to know what tests you should request and which laboratory to use?  Have you already had celiac DQ genetic testing but are not sure what the results mean or what your risk is of developing celiac disease or gluten sensitivity? These are the questions I will answer in the next few pages. 
    What is HLA DQ celiac genetic testing?
    To understand celiac DQ genetics and the risk estimates you must also understand how the DQ types are determined and some basic terminology.  Each of us has 46 chromosomes, 23 pairs received from our parents.  We all have two copies of chromosome 6, one from each parent.  Homozygous is w...

    Celiac.com 09/09/2011 - A team of researchers recently set out to assess the effects of milk-feeding behavior and the HLA-DQ genotype on intestinal colonization of Bacteroides species in infants with a risk of developing celiac disease.
    The research team included E. Sánchez, G. De Palma, A. Capilla, E. Nova, T. Pozo, G. Castillejo, V. Varea, A. Marcos, J. A. Garrote, I. Polanco, A. López, C. Ribes-Koninckx, M. D. García-Novo, C. Calvo, L. Ortigosa, F. Palau, and Y. Sanz.
    They are affiliated with the Ecofisiología Microbiana y Nutrición, Instituto de Agroquímica y Tecnología de Alimentos (CSIC) in Valencia, Spain.
    The team studied 75 full-term newborns with at least one first-degree relative who suffered from celiac disease. They classified the newborns according to milk-feedin...

    Celiac.com 06/24/2013 - Researchers don't know much about the genetic history of celiac disease. They know especially little about the age of specific gene sequences that leave people at risk for developing celiac disease.
    A recent case study provides a small bit of information about that question. The information was gathered by a team of researchers looking into the case of a young, first century AD woman, found in the archaeological site of Cosa. The woman's skeleton showed clinical signs of malnutrition, such as short height, osteoporosis, dental enamel hypoplasia and cribra orbitalia, indirect sign of anemia, all strongly suggestive for celiac disease.
    The research team included G. Gasbarrini, O. Rickards, C. Martínez-Labarga, E. Pacciani, F. Chilleri, L. Laterza, G. Marangi,...
