Four functional polymorphisms (rs3821236, rs7574865, rs7574070, and rs897200) located within STAT4 gene as well as three independent polymorphisms (rs7517847, rs11209026, and rs1495965) located within IL23R were genotyped using TaqMan® allelic discrimination in a total of 206 patients with non-anterior uveitis and 1553 healthy controls from Spain.
The strongest association was observed in dermatomyositis, with an OR of 3.07 (95% CI; 1.57-6.02) for the carriers of four risk alleles at the two SNP sites, namely, rs1327713 and rs7574865.

A case-control study was carried out on IRF5 rs10954213 and STAT4 rs7574865 in 232 Japanese myeloperoxidase (MPO)-ANCA-positive AAV patients, including 177 microscopic polyangiitis and 710 healthy controls.
Current study results support that functional STAT4 (rs7574865), IL23R (rs11209032), and STAT3 (rs744166) variants may associate with occurrence, severity, and immunosuppressive outcome of AA in the Han population in southwest China.
Our data suggest that patients with early arthritis who are homozygous for the T allele of rs7574865 in STAT4 may develop a more severe form of the disease with increased disease activity and disability.
Significant evidence for association with susceptibility to PsA was found toa SNP mapping to the REL (rs13017599, p(trend)=5.2×10(4)) gene, while nominal evidence for association (p(trend)<0.05) was found to seven other loci including PLCL2 (rs4535211, p=1.7×10(-3)); STAT4 (rs10181656, p=3.0×10(-3)) and the AFF3, CD28, CCL21, IL2 and KIF5A loci.
An association of STAT4 (rs10181656) with PsA was confirmed whereas CD226 (rs763361) was associated with PsA but not with RA, in contrast to previous reports.
Furthermore, having TG + GG genotypes on rs1031509 near STAT4 was associated with 5-times (95% CI, 3.03-8.55) greater odds of asthma diagnosis at the highest B[a]P range, compared to the odds at the reference range.
Five SNPs, rs3733475A/C (IRF2), rs2069832A/G (IL6), rs2012075G/A (IFNGR2) and rs1400656G/A (STAT4) and rs1805011C/A (IL4RA) were found to be associated with asthma in family based as well as in case-control analyses (P=0.002, P=0.001, P=0.004, P=0.003 and P=0.001, respectively).
We conclude that rs7574865 and rs7582694 in <i>STAT4</i> gene minor alleles, interaction between rs7582694 and rs2476601, and haplotype containing the rs7582694-C and rs7574865-T alleles are associated with increased type 1 AIH risk, but rs2476601 in <i>PTPN22</i> gene minor allele is associated with decreased type 1 AIH risk.

Here we demonstrate for the first time, in a genetically homogeneous population, the association of the STAT4 rs7574865 G/T polymorphism, which has been shown to be associated with these autoimmune diseases, with susceptibility to type 1 diabetes (T1D).
Taking into consideration that the different autoimmune diseases may share some common pathogenetic pathways, the aim of the present study was to evaluate the role of STAT4 rs7574865 polymorphism on acute allograft rejection.
