• DQA1
  • There is only one common cis-isoform of DQ8 because the linked DQA1*03 alleles(2) occur over the majority of the population, DQ8.1 is the overwhelming majority cis-isoform of DQ8. (wikipedia.org)
  • Infrequently, DQA1*0302:DQB1*0302, but this substitution of the alpha chain, DQA1**0301 versus *0302, is outside the binding cleft and appears not to alter DQ8 function. (wikipedia.org)
  • phenotype
  • Dominant inheritance of a milder APS1 phenotype has been described recently due to heterozygous AIRE gene mutations that inactivate the normal allele (dominant negative mutations). (springer.com)
  • autoantibody
  • Two distinctly HLA-associated contiguous linear epitopes uniquely expressed within the islet antigen 2 molecule are major autoantibody epitopes of the diabetes-specific tyrosine phosphatase-like protein autoantigens. (ld.ru)
  • Individuals with high risk human leukocyte antigen, autoantibody, andgenotypic profiles still escape overt disease, while in contrast individualswith low risk factors can progress to type 1 diabetes. (ufl.edu)
  • chromosome
  • The major histocompatibility complex (MHC), located on the short arm of Chromosome 6, is one of the most extensively studied regions in the human genome because of the contribution of multiple variants at this locus in autoimmune, infectious, and inflammatory diseases and in transplantation. (plos.org)
  • variants
  • The major histocompatibility complex (MHC) is one of the most extensively studied regions in the human genome because of the association of variants at this locus with autoimmune, infectious, and inflammatory diseases. (plos.org)
  • An individual's HLA variants influence peptide binding and signal transduction after T cell receptor (TCR) engagement. (jci.org)
  • immune cells
  • Genetically predisposed individuals could be influenced by an environmental trigger (i.e., dietary iodine, infection, pregnancy, cytokine therapy) that induces an autoimmune response against thyroid-specific antigens by infiltrating immune cells. (springer.com)
  • partially
  • The risk is partially shared with the HLA-DR locus (DR3 and DR4 serotypes). (wikipedia.org)
  • DQ8 is determined by the antibody recognition of β8 and is complicated by the fact that DQ8 recognizes some HLA-DQB1*03 encoded isoforms well, partially or not well at all (See serology) DQ β3.2 and β3.5 are best recognized as DQ8. (wikipedia.org)
  • thyroid
  • GAD65 antibody prevalence and association with thyroid antibodies, HLA-DR in Chinese children with type 1 diabetes mellitus. (ld.ru)
  • Human
  • Shortly afterward, Jean Dausset recognized the human MHC, or human leukocyte antigen (HLA) region, so named because Dausset originally demonstrated MHC antigens on the surface of white blood cells . (plos.org)
  • high
  • 1 ) Puerto Rican case and control subjects, 2 ) Mexican-American simplex families, and 3 ) high-risk (DR3/DR4) individuals with and without an affected relative. (diabetesjournals.org)
  • Therefore, it is prudent to use high resolution DQB1 typing for DQ8. (wikipedia.org)
  • risk
  • DQ8 increases the risk for rheumatoid arthritis and is linked to the primary risk locus for RA, HLA-DR4. (wikipedia.org)
  • Although false reaction with DQB1*0302 is low, the efficiency of the positive reaction is not good and there is a risk of false detection of DQB1*0305 which could create incompatibility. (wikipedia.org)
  • common
  • HLA-A2 is also common in the general population, being present in about 50% of individuals of European descent. (jci.org)
  • cells
  • Studies of organ donors with T1D that have examined T cells in pancreas, the diabetogenic insulitis lesion, and lymphoid tissues have revealed a broad repertoire of target antigens and T cell receptor (TCR) usage, with initial evidence of public TCR sequences that are shared by individuals with T1D. (jci.org)
  • disease
  • However, genotype at thers2069762 locus did not directly associate with disease state. (ufl.edu)
  • patients
  • HLA-DR and -DQ gene polymorphism in Latvian patients with insulin-dependent diabetes mellitus. (ld.ru)
