Swedish Twin Registry

Overview of Services

The Swedish Twin Registry (STR) is the world's largest of its kind and has become an invaluable resource for medical research.

Established in the 1960s, the Registry houses data on approximately 85,000 twin pairs with known zygosity, encompassing both monozygotic and dizygotic pairs. Research spans a wide array of public health topics, including allergies, cancer, dementia, and cardiovascular disease.

Since its inception at the Karolinska Institutet in 1959, STR was originally focused on exploring the environmental influences on cardiovascular disease and cancer development. Over time, its scope has expanded to encompass nearly all common diseases and health issues. Having reached out to all living twins, STR now stands as the world's largest twin registry. The data from STR has contributed to a significant number of scientific publications, with nearly 100 new papers published annually.
