BACKGROUND: Although genome-wide association studies (GWAS) have identified over
100 genetic loci associated with rheumatoid arthritis (RA), our ability to
translate these results into disease understanding and novel therapeutics is
limited. Most RA GWAS loci reside outside of protein-coding regions and likely
affect distal transcriptional enhancers. Furthermore, GWAS do not identify the
cell types where the associated causal gene functions. Thus, mapping the
transcriptional regulatory roles of GWAS hits and the relevant cell types will
lead to better understanding of RA pathogenesis. RESULTS: We combine the
whole-genome sequences and blood transcription profiles of 377 RA patients and
identify over 6000 unique genes with expression quantitative trait loci (eQTLs).
We demonstrate the quality of the identified eQTLs through comparison to non-RA
individuals. We integrate the eQTLs with immune cell epigenome maps, RA GWAS risk
loci, and adjustment for linkage disequilibrium to propose target genes of immune
cell enhancers that overlap RA risk loci. We examine 20 immune cell epigenomes
and perform a focused analysis on primary monocytes, B cells, and T cells.
CONCLUSIONS: We highlight cell-specific gene associations with relevance to RA
pathogenesis including the identification of FCGR2B in B cells as possessing both
intragenic and enhancer regulatory GWAS hits. We show that our RA patient cohort
derived eQTL network is more informative for studying RA than that from a healthy
cohort. While not experimentally validated here, the reported eQTLs and cell
type-specific RA risk associations can prioritize future experiments with the
goal of elucidating the regulatory mechanisms behind genetic risk associations.
