摘要: A preponderance of females develop autoimmune disease, including juvenile idiopathic arthritis (JIA), yet the reason for this bias remains elusive. Evidence suggests that genetic risk disease may be influenced by sex. PTPN22 rs2476601 is associated with JIA and numerous other diseases, has been reported to show female-specific association type 1 diabetes. We performed main effect sex-stratified analyses determine whether a sex-specific exists in JIA. As expected, was our discovery (413 cases 690 controls) replication (1008 9284 samples. Discovery sample demonstrated an specifically (odds ratio (OR)=2.35, 95% confidence interval (CI)=1.52-3.63, P=0.00011) but not males (OR=0.91, CI=0.52-1.60, P=0.75). This similarly observed sample. There evidence genotype-by-sex interaction (Pinteraction=0.009). The between appears restricted females, partly accounting predominance disease.
