“…Recently, STAT4 haplotype characterized by the rs7574865 polymorphism was reported to be significantly associated with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and other autoimmune diseases such as Sjögren's syndrome, type 1 diabetes, and systemic sclerosis [16][17][18]. Interestingly, a recent casecontrol study conducted in a Spanish population showed that the T allele of the STAT4 rs7574865 was associated with IBD [19], and this association has been replicated by Diaz-Gallo et al [20] and Glas et al [21], they reported that rs7574865 polymorphism was associated with colonic CD and early disease onset in Caucasians. However, there are also some other studies did not confirm these findings.…”
