Abstract
-
Rheumatoid arthritis (RA) is a chronic autoimmune disease that mainly involves the joints. Although the full etiology remains unclear, both genetic and environmental factors contribute to disease. Recently, genetic studies of RA, which include whole-genome linkage study, candidate gene association study, and especially genome-wide association study, made much progress through the advances in technology and large collection of case-controls. These various approaches provided new susceptible genes such as PTPN22, PADI4, STAT4, TNFAIP3, TRAF1-C5, CD40 gene in addition to HLA-DRB1. This review will cover an update in recent progress in RA genetics, focusing mainly on the several novel loci.
