This hybrid case-parent triad and case-control study examined associations between 76 tagSNPs in IL10 and IL12 cytokine pathway genes (IL10, IL12A, IL12B, IL10RA, IL10RB, IL12RB1, IL12RB2) and cervical/vulvar cancer risk. Key findings include: IL10RA rs9610 (OR=1.76, 95% CI 1.15–2.68) and rs4252314 (OR=2.23, 95% CI 1.26–3.96) associated with increased cervical cancer risk; IL12RB2 rs4297265 (OR=0.46) and rs2229546 (OR=0.43) associated with reduced cervical SCC risk; IL12B rs3181224 associated with reduced vulvar SCC risk (OR=0.30, 95% CI 0.12–0.74); and IL12RB1 rs11575934 (OR=1.51, 95% CI 1.12–2.05) associated with increased cervical adenocarcinoma risk.

Meta-analysis of 11 studies examining IL12B polymorphisms rs3212227 and rs6887695 in psoriasis and psoriatic arthritis. For rs3212227, pooled odds ratios for the minor allele were 0.688 (95% CI 0.650-0.729) for psoriasis and 0.707 (95% CI 0.628-0.797) for PsA; for rs6887695, pooled ORs were 0.704 (95% CI 0.670-0.739) for psoriasis and 0.677 (95% CI 0.599-0.767) for PsA, demonstrating significant protective associations with both variants.

This study examined 40 SNPs (34 CD-associated and 6 UC-associated) in 2374 Canadian IBD patients (1144 CD, 1230 UC/IBDU) and 1057 healthy controls. While most immune-related variants showed similar frequencies between CD and UC, the two diseases diverged significantly in genes related to innate immunity and autophagy (NOD2, ATG16L1, IRGM), which were more prevalent in CD. In patients with colon-only CD, genetic overlap with UC was nearly complete, suggesting a shared genetic basis for colonic disease.

A candidate gene study of 837 psoriasis cases and 816 controls identified protective variants in IL-23 signaling genes. IL23R p.Arg381Gln (rs11209026) showed reduced frequency in cases vs controls (P=0.00014, OR=0.49). IL12B variants rs10045431 (P=0.0001, OR=1.41) and rs3212227 (P=0.036, OR=0.76) showed independent associations, establishing IL23 receptor signaling as a major pathway in psoriasis susceptibility.
