[EX Q]: Question: Are variants in TNFAIP3 , STAT4 , and C12orf30 loci associated with multiple autoimmune diseases also associated with juvenile idiopathic arthritis?
Answer: We have demonstrated associations between JIA and variants in the TNFAIP3, STAT4, and C12orf30 regions that have previously shown associations with other autoimmune diseases, including RA and systemic lupus erythematosus. Our results suggest that clinically distinct autoimmune phenotypes share common genetic susceptibility factors.
