Sequencing of the MHC Region Defines HLA-DQA1 As Driven Risk for Anti-Citrullinated Protein Antibodies (ACPA)-Positive Rheumatoid Arthritis in Han Population
Background/Purpose: The strong genetic contribution of the major histocompatibility complex (MHC) to rheumatoid arthritis (RA) susceptibility has been generally attributed to HLA-DRB1. However, due to…Abstract Number: 2431 • 2017 ACR/ARHP Annual Meeting
Acquisition of Protective Alleles in Women with Rheumatoid Arthritis through Microchimerism
Background/Purpose: As in many autoimmune diseases, rheumatoid arthritis (RA) has a female predominance and strong genetic susceptibility from the HLA region. The shared epitope (SE),…Abstract Number: 3121 • 2016 ACR/ARHP Annual Meeting
Specific Antibody Subphenotypes in Rheumatoid Arthritis Are Associated with Unique HLA-DRB1 Residues at Position 11
Background/Purpose: Antibody to citrullinated peptides/proteins (ACPA) is specific feature of rheumatoid arthritis (RA) and seen in 50 to 70% of RA patients. Amino acid (AA)…Abstract Number: 3074 • 2015 ACR/ARHP Annual Meeting
The Shared Rheumatoid Arthritis HLA-DRB1 Susceptibility Epitope Shapes the Molecular Orientation of Citrulline and the Autoreactive T Cell Receptor Repertoire
Background/Purpose: Large-scale genomic studies have identified many genetic associations with autoimmune diseases, but the precise pathogenetic mechanisms by which the associated genes impact disease susceptibility…Abstract Number: 1476 • 2014 ACR/ARHP Annual Meeting
A Dose Response Relationship Between Shared Epitope and ACPA Level: But Not All SE Alleles Are Created Equal
Background/Purpose: Indigenous North American populations have high prevalence of seropositive RA. The Cree/Ojibway population in Central Canada and the Alaska Native population have a high prevalence…Abstract Number: 808 • 2013 ACR/ARHP Annual Meeting
A Genome Wide Association Study Of Rheumatoid Arthritis Without Antibodies Against Citrullinated Peptides
Background/Purpose: Rheumatoid arthritis (RA) is a common autoimmune disease that is associated with a progressive loss of the joints induced by a chronic inflammation of…Abstract Number: 1210 • 2012 ACR/ARHP Annual Meeting
Effect of HLA-DRB1*0901 Suggest Distinctive Mechanisms of Rheumatoid Arthritis Susceptibility
Background/Purpose: Although HLA-DRB1 shared epitope (SE) alleles and DRB1*0901 have repeatedly been shown to be associated with RA susceptibility, the effect of each allele on…Abstract Number: 976 • 2012 ACR/ARHP Annual Meeting
Effect of Interactions Between Validated Rheumatoid Arthritis Genetic Factors and Environmental Factors On Rheumatoid Arthritis Risk
Background/Purpose: Studies have shown associations between environmental factors and rheumatoid arthritis (RA) risk. Also, genome-wide association studies (GWAS) have identified genetic markers associated with RA…Abstract Number: 439 • 2012 ACR/ARHP Annual Meeting
Interaction of Antibodies Against Citrullinated Peptides with HLA Shared Epitope, PTPN22 1858T Variant, and Smoking in Individuals Prior to and After the Development of Rheumatoid Arthritis
Background/Purpose: The presence of antibodies against cyclic citrullinated peptides (ACPA) has been demonstrated to precede the development of rheumatoid arthritis (RA) by several years. The…Abstract Number: 412 • 2012 ACR/ARHP Annual Meeting
Single Nucleotide Polymorphisms within the HLA-DRB1 Gene in Relation to Antibodies Against Citrullinated Peptides in Individuals Prior to the Development of Rheumatoid Arthritis
Background/Purpose: Multiplex analysis has demonstrated the presence of several antibodies against cyclic citrullinated peptides (ACPA) preceding the development of rheumatoid arthritis (RA) by several years.…
