Abstract
Rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are chronic inflammatory diseases that together affect 2-3% of the population. RA and AS predominantly involve joints, but heart disease is also a common feature in RA and AS patients. Here we have studied a new spontaneous mutation that causes severe polyarthritis in bone phenotype spontaneous mutation 1 (BPSM1) mice. In addition to joint destruction, mutant mice also develop aortic root aneurism and aorto-mitral valve disease that can be fatal depending on the genetic background. The cause of the disease is the spontaneous insertion of a retrotransposon into the 3' untranslated region (3'UTR) of the tumor necrosis factor (TNF), whic..
