title: The genetics of spondyloarthropathies.
abstract: The spondyloarthropathies constitute a group of inflammatory joint diseases linked by shared characteristics that include a strong common genetic background. Genetic factors include major histocompatibility complex (MHC) genes, among which HLA-B27 contributes 30% of the overall genetic susceptibility to spondyloarthropathies, and non-MHC genes, none of which have been identified to date. Genome screens have identified regions that may contain susceptibility genes for spondyloarthropathies. In particular, a locus on the long arm of chromosome 9 (9q31-34) was identified by two groups working independently from each other. Studies using the candidate gene approach ruled out a role for most of the tested genes, including CARD15/NOD2. However, several independent groups have reported significant associations between ankylosing spondylitis and the IL-1 gene cluster on the long arm of chromosome 2.
