Abstract
The aim of this study was to determine whether the functional integrin-α-M (ITGAM) rs1143679 polymorphism is associated with susceptibility to systemic lupus erythematosus (SLE), lupus nephritis (LN), and rheumatoid arthritis (RA). A series of meta-analyses were conducted to test for associations between the ITGAM rs1143679 polymorphism and SLE, LN, or RA. A total of 24 comparisons involving 7,738 patients and 8,309 controls for SLE, and 2,663 patients and 2,694 controls in RA were considered. Meta-analysis showed a significant association between the ITGAM rs1143679 A allele and SLE in all subjects (OR 1.773, 95 % CI 1.656, 1.901, p < 1.0 × 10−9). After stratification by ethnicity, the A allele was found to be significantly associated with SLE in European, Latin American, and Asian. A significant association was also found between the ITGAM A allele and lupus nephritis in Europeans (OR 2.131, 95 % CI 1.565, 2.903, p = 1.6 × 10−7). However, no association was found between RA and the ITGAM rs1143679 polymorphism. Our meta-analyses confirm that the ITGAM rs1143679 polymorphism is associated with SLE susceptibility in different ethnic groups and demonstrate that the polymorphism is associated with LN in European.
