Swedish Twin Registry

Overview of Services

The Swedish Twin Registry is the largest of its kind in the world and it has become an invaluable resource for medical research.

The Registry was established in the 1960s and contains information about some 85 000 twin pairs with zygosity known. 
Data is generated from both mono- and dizygotic pairs. The studies cover a variety of topics on public health issues such
as allergies, cancer, dementia and cardiovascular disease.

STR is domiciled at the Karolinska Institutet since 1959. It was originally established to study the importance of the environment
for the development of cardiovascular disease and cancer. Since then, interest has expanded to cover almost all common diseases
and health problems. We have contacted all alive twins and we are now the world's largest twin registry. A substantial number of
scientific articles have been published on data from STR and more than 50 new articles are published every year.
