Retrospective analysis of sequence variants in six genes (PTPN22, STAT4, TRAF1/C5 locus, TGFB, TNFAIP3, and C12orf30) associated with JIA or other autoimmune/inflammatory conditions did not reveal association with uveitis across all JIA sub-forms [71]. Here, TGFB1 is linked to juvenile idiopathic arthritis.
