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.

Genome-wide association study of 116 children with cardiac neonatal lupus (116 cases, 3,351 controls) identified 17 significant SNPs in the HLA region at 6p21, with the strongest association at rs3099844 (OR 3.34, P=4.52×10⁻¹⁰) near the MICB gene. Non-HLA associations were found at rs743446 (21q22, OR 2.40, P=5.45×10⁻⁶), rs2403106 (12q21, OR 2.48, P=2.62×10⁻⁶), rs1391511 (10p15, OR 1.84, P=6.6×10⁻⁶), and rs1890645 (1q31, OR 2.98, P=3.52×10⁻⁶). Results suggest genetic polymorphisms in inflammatory and apoptotic pathways contribute to cardiac injury in fetuses exposed to maternal anti-Ro/SSA antibodies.
