This meta-analysis of 7 genome-wide association studies identified three novel multiple sclerosis susceptibility loci: rs170934 near EOMES (3p24.1, OR=1.17, P=1.6×10⁻⁸), rs2150702 in MLANA (9p24.1, OR=1.16, P=3.3×10⁻⁸), and rs6718520 near THADA (2p21, OR=1.17, P=3.4×10⁻⁸). The analysis encompassed 5,545 cases and 12,153 controls and identified 10 additional loci with suggestive evidence of association (P<1×10⁻⁶), including IL12B, TAGAP, PLEK, and ZMIZ1, which are shared with other inflammatory diseases.

This case-control association study of juvenile idiopathic arthritis (JIA) in 809 JIA cases and 3,521 controls identified susceptibility loci shared with other autoimmune diseases. Three novel loci were identified: PTPN2 (strongest signals rs7234029, p=7.19×10⁻¹¹, OR=1.59; rs1893217, p=3.48×10⁻⁸, OR=1.52; rs2542151, p=3.05×10⁻⁷, OR=1.45), COG6 (rs7993214, p=3.98×10⁻³, OR=0.79), and ANGPT1 (rs1010824, p=4.93×10⁻³, OR=0.77). Four previously reported JIA loci were confirmed: PTPN22, STAT4, C12orf30, and IL2-IL21. Odds ratios ranged from 1.20 to 1.65 in meta-analysis of initial and independent replication cohorts (n=1,015 cases and 1,568 controls).
