Because both environment and genetic factors can contribute to the development of rheumatoid arthritis, some relatives of patients with rheumatoid arthritis (RA) will be at increased risk of developing RA themselves.
The aim of this study, which is being run by The University of Manchester, is to create a national database of close relatives of patients with rheumatoid arthritis, who are not affected by the condition themselves. The study will look at the risk of developing RA using questionnaires to assess lifestyle factors, and analysis of blood samples to assess genetic links.
Close relatives (parents, siblings, half-siblings or adult children) of someone with rheumatoid arthritis. Participants must be aged over 30 and not have any inflammatory arthritis themselves.
