Polygenic Analysis of Transport, Metabolism and Immune Related Genomic Compartments in Serum Urate and Gout
Background/Purpose: Genome wide association studies (GWAS) have identified loci associated with complex traits, and the current challenge is to glean biological insights from these findings.…Abstract Number: 880 • 2014 ACR/ARHP Annual Meeting
An Immunochip Study Confirms a Strong Contribution of HLA Class I and II Genes in the Susceptibility to Giant Cell Arteritis
Background/Purpose: Giant cell arteritis (GCA) is a chronic autoimmune vasculitis with an important genetic component. We aimed to identify relevant risk loci for GCA predisposition…Abstract Number: 2959 • 2014 ACR/ARHP Annual Meeting
Twenty-Eight Loci That Influence Serum Urate Levels: Analysis of Association with Gout
Background/Purpose: Twenty-eight genetic loci are associated with serum urate levels in Europeans. Ten are established, with a further 18 of weaker effect more recently detected.…Abstract Number: 765 • 2014 ACR/ARHP Annual Meeting
Gene-Gene Interaction of IRF5 and BLK Polymorphisms in US and Spanish Cohorts of Systemic Sclerosis (SSc)
Background/Purpose Systemic sclerosis (SSc) is a complex autoimmune disease and several genetic loci increasing SSc susceptibility have been identified with small to modest effect sizes.…Abstract Number: 2961 • 2014 ACR/ARHP Annual Meeting
Conditional Analysis of 30 Serum Urate Loci Identifies 25 Additional Independent Effects
Background/Purpose: Single variants in 30 genetic loci have been associated with serum urate levels in Europeans by meta-analysis of summary statistics of 48 individual genome-wide…Abstract Number: 625 • 2014 ACR/ARHP Annual Meeting
Fine-Mapping Major Histocompatibility Complex Associations Identified Contribution of Multiple Class I and II HLA Genes on Risk of Psoriasis and Its Clinical Subtypes
Background/Purpose: Psoriasis vulgaris (PsV) risk is strongly associated with genetic variation within the major histocompatibility complex (MHC) region, although its fine genetic architecture has not…Abstract Number: 2953 • 2014 ACR/ARHP Annual Meeting
International Immunochip Study in the Idiopathic Inflammatory Myopathies Identifies Novel Susceptibility Loci and Confirms HLA As Strongest Genetic Risk Factor

Association of TRIM21 (RO52) Polymorphisms with Systemic Lupus Erythematosus in a Japanese Population
Background/Purpose TRIM21, also referred to as Ro52 or SS-A1, belongs to the tripartite motif-containing (TRIM) family. TRIM21 is not only important as an autoantigen, but…Abstract Number: 2918 • 2014 ACR/ARHP Annual Meeting
Fine-Mapping Major Histocompatibility Complex Associations in ACPA-Positive Rheumatoid Arthritis Identified Shared HLA Amino Acid Polymorphisms in Asian and European Populations
Background/Purpose: Rheumatoid arthritis (RA) risk is strongly associated with variations within the major histocompatibility complex (MHC) region, and in particular to HLA-DRB1 alleles. We aimed…Abstract Number: 86 • 2014 ACR/ARHP Annual Meeting
Association of Leukocyte Immunoglobulin-like Receptor A3 (LILRA3) with Systemic Sclerosis
Background/Purpose: The leukocyte immunoglobulin-like receptors (LILRs) are a gene family located in leukocyte receptor complex at 19q13.4. LILRs are expressed mainly in immune cells as…Abstract Number: 2841 • 2014 ACR/ARHP Annual Meeting
Identifying Novel Lupus Severity Risk Variants through Identification of Alleles with High Ethnic Variability Worldwide
