The cause of rheumatoid arthritis is not yet known. However, it is known that RA is an autoimmune disease. The body s natural immune system does not operate as it should, resulting in the immune system attacking healthy joint tissue and causing inflammation and subsequent joint damage. Researchers suspect that agent-like viruses may trigger RA in some people who have an inherited tendency for the disease. Many people with RA have a certain genetic marker called HLA-DR4. Researchers know that there are other genes that influence the development of RA.
