Genetic susceptibility to SLE: new insights from fine mapping and genome-wide association studies

Abstract
Recent advances in genotyping technology have identified or confirmed more than 20 loci that are associated with susceptibility to systemic lupus erythematosus (SLE). These findings add detail to our current understanding of the molecular basis of this complex disease and provide new avenues for investigation. Genome-wide association studies and fine mapping of candidate regions have rapidly advanced our understanding of the genetic basis of systemic lupus erythematosus (SLE). More than 20 robust associations have now been identified and confirmed, providing insights at the molecular level that refine our understanding of the involvement of host immune response processes. In addition, genes with unknown roles in SLE pathophysiology have been identified. These findings may provide new routes towards improved clinical management of this complex disease.
