A two-stage genome-wide association study of 649 early-onset myasthenia gravis patients identified HLA-B*08 as the major genetic risk factor (OR=6.41, p=2.87×10⁻¹¹³) and TNIP1 Pro151Ala (rs2233290, OR=1.92, p=3.4×10⁻⁹) as a novel non-HLA locus. Together with PTPN22 (rs2476601, OR=1.71, p=8.2×10⁻¹⁰), these loci account for 62.9% of population attributable risk, implicating dysregulation of NF-κB signaling pathways in myasthenia gravis pathogenesis.

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.

Genome-wide association study and replication study identifying susceptibility genes for alcohol dependence in 1460 German male patients with early-onset alcohol dependence and 2332 controls. Two SNPs met genome-wide significance: rs7590720 (p=9.72×10⁻⁹) and rs1344694 (p=1.69×10⁻⁸) on chromosome 2q35 near the PECR gene. Nine additional SNPs showed significant replication in genes including CDH13, ADH1C, CAST, and ERAP1.

A case-control association study of 281 Japanese systemic sclerosis (SSc) patients and 477 healthy controls examined three IRF5 SNPs (rs2004640, rs10954213, rs2280714) previously associated with systemic lupus erythematosus. rs2280714 showed the strongest association with SSc (OR 1.42, P=0.0012 in all SSc; OR 1.70, P=0.00013 in diffuse cutaneous SSc). The rs2004640 association was replicated in the recessive model, particularly in the anti-topoisomerase I antibody-positive subset.
