Graphic analysis of population structure on genome-wide rheumatoid arthritis data
Principal-component analysis (PCA) has been used for decades to summarize the human genetic variation across geographic regions and to infer population migration history. Reduction of spurious associations due to population structure is crucial for the success of disease association studies. Recently, PCA has also become a popular method for detecting population structure and correction of popu...
متن کاملAn integrated genome-wide association analysis on rheumatoid arthritis data
We propose a nonparametric association analysis combining both family and unrelated case-control genotype data. Under the assumption of Hardy-Weinberg equilibrium, we formed an affected group to compare with a group of unaffecteds.Comparison with traditional case-control chi-square test and transmission-disequilibrium test shows that this new approach has noticeably improved power. All analysis...
متن کاملPathway analysis of genome-wide association studies on rheumatoid arthritis.
OBJECTIVES The aims of this study were to identify candidate single nucleotide polymorphisms (SNPs) and candidate mechanisms of RA and generate hypotheses for SNP 'gene' pathways. METHODS We used a meta-analysis dataset of rheumatoid arthritis (RA) genome-wide association studies (GWAS) which included 2,554,714 SNPs in 5,539 RA cases and 20,169 controls of European descent. ICSNPathway (Ident...
متن کاملA genome-wide ordered-subset linkage analysis for rheumatoid arthritis
Rheumatoid arthritis (RA) is a chronic, complex autoimmune inflammatory disorder with poorly known etiology. Approximately 1% of the adult population is afflicted with RA. Linkage analysis of RA can be complicated by the presence of phenotypic and genetic heterogeneity. It is shown that the ordered-subset analysis (OSA) technique reduces heterogeneity, increases statistical power for detecting ...
متن کاملGenome-wide linkage and association analysis of rheumatoid arthritis in a Canadian population
Rheumatoid arthritis (RA) is an autoimmune disease with a moderately strong genetic component. Previous linkage and candidate gene studies have identified several regions that predispose to RA, including the HLA-DRB1 and PTPN22. We conducted genome-wide linkage analysis with 128 affected individuals from 60 families in a Canadian cohort that were genotyped using the Illumina linkage panel and g...
