Twin Research for a healthy future

Join the largest twin registry in the UK to help advance health research

Join the largest twin registry in the UK to help advance health research.

Professor Tim Spector from King’s College London set up the cohort in 1992 to investigate the incidence of osteoporosis and other rheumatologic diseases in several hundred monozygotic (identical) twins. We now have over 15,000 identical and non-identical twins from across the UK, with ages between eighteen and one hundred and our research has expanded to include multiple diseases and conditions.

Engagement

The Department of Twin Research endeavours to share its research findings with the public and the media wherever possible. We have both an extensive public engagement programme, as well as a strong history of media coverage, often featuring our twin volunteers.

What our twins say about us

“We have been part of Twin Research for many years now. We thoroughly enjoy our visits to the team in London, who are always friendly and cheerful. Through Twin Research, we found out we were identical twins from our completed questionnaires. We were always told by Mum that we were fraternal twins. Thank you, Twin Research, for confirming our suspicions! 👩‍❤️‍👩 ”
