Two-stage case-control association study in 738 Han Chinese Behcet's disease patients with ocular involvement and 1,873 controls identified three JAK1 SNPs (rs2780815, rs310241, rs3790532) significantly associated with disease susceptibility (Pc=0.030-1.90×10⁻⁴) with population attributable risks of 35.0%, 28.0%, and 27.0% respectively. No significant associations were found for SLC22A4, SLC22A5, or RUNX1 polymorphisms.

This case-control study in 469 Czech Crohn's disease (CD) patients and 470 controls examined the IBD5 locus, identifying two independent genetic factors: rs6596075 (OR=0.70, protective allele G, p=0.018 in dominant model) and the haplotype tagged by rs2188962 and IGR2063b_1 (OR=1.38 for IGR2063b_1, p=0.00075 in log-additive model). The study demonstrates that these two genetic factors independently contribute to CD susceptibility at the IBD5 locus.

A meta-analysis of 4,107 type 2 diabetes cases and 5,187 controls from three GWA studies found no evidence that common variants altering circulating inflammatory protein levels (IL-18, IL-6R, CRP, IL1RN, PAI1, MIF) or variants predisposing to autoimmune diseases (type 1 diabetes, rheumatoid arthritis, Crohn's disease, celiac disease, multiple sclerosis, SLE) are associated with type 2 diabetes risk. For example, rs2250417 in IL18 showed OR=1.00 (95% CI 0.99-1.03) versus the expected OR of ~1.15 if inflammation were causal, suggesting inflammatory markers are likely secondary rather than causative in type 2 diabetes.
