Population stratification—allele frequency differences between cases and controls due to
systematic ancestry differences—can cause spurious associations in disease studies. We …

To identify new genetic risk factors for rheumatoid arthritis, we conducted a genome-wide
association study meta-analysis of 5,539 autoantibody-positive individuals with rheumatoid …

To identify susceptibility alleles associated with rheumatoid arthritis, we genotyped 397
individuals with rheumatoid arthritis for 116,204 SNPs and carried out an association analysis in …

To identify rheumatoid arthritis risk loci in European populations, we conducted a meta-analysis
of two published genome-wide association (GWA) studies totaling 3,393 cases and …

We present a robust, fully automatable technology platform that includes computer software
for the detailed analysis of low femtomoles of N-linked sugars released from glycoproteins. …

Tetralogy of Fallot (TOF), the most common severe congenital heart malformation, occurs
sporadically, without other anomaly, and from unknown cause in 70% of cases. Through a …

To discover new rheumatoid arthritis (RA) risk loci, we systematically examined 370 SNPs
