摘要

Genome-wide association studies (GWAS) have identified several immune-related loci associated with systemic sclerosis (SSc), which clearly supports the idea that the immune system plays an important role in the disease etiology (, 2). Using gene set enrichment analysis and DAVID algorithms in the Biocarta pathway collection, we found that the most enriched pathways in SSc corresponded to the nitric oxide synthase 2-dependent interleukin-12 (IL-12) pathway in natural killer cells and the IL-12/STAT-4-dependent signaling pathway in Thl development (see Supplementary Table , available on the Arthritis & Rheumatology web site at http:// onlinelibrary.wiley.com/doi/10.1002/art.38870/abstract). Moreover, several studies have implicated IL-12 in autoimmune inflammatory processes (3). Interestingly, in our recent large-scale fine mapping Immunochip study in SSc (4), we observed suggestive association signals in the IL12RB1 locus, which encodes the /31 subunit of the IL-12 receptor. Consequently, we aimed to evaluate for the first time the genetic contribution of the IL12RB1 region in SSc through a followup study.
