The DTR currently comprises of more than 175,000 twins from the 140 birth cohorts. This makes the DTR the oldest nationwide twin register and among the largest in the world. The combination of data from several surveys, including biological samples and repeated measurements on the same individuals, and data from Danish national registers provides a unique resource for a wide range of twin studies. This article provides an updated overview of the data in the DTR: First, we provide a summary of the establishment of the register, the different ascertainment methods and the twins included; then follows an overview of major surveys conducted in the DTR since 1994 and a description of the DTR biobank, including a description of the molecular data created so far; finally, a short description is given of the linkage to Danish national registers at Statistics Denmark and some recent examples of studies using the various data resources in the DTR are highlighted.<\/jats:p>","DOI":"10.1017\/thg.2019.72","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T10:20:08Z","timestamp":1569234008000},"page":"499-507","source":"Crossref","is-referenced-by-count":85,"title":["The Danish Twin Registry: An Updated Overview"],"prefix":"10.1017","volume":"22","author":[{"given":"Dorthe Almind","family":"Pedersen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisbeth Aagaard","family":"Larsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Nygaard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonas","family":"Mengel-From","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matt","family":"McGue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Dalg\u00e5rd","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Hvidberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob","family":"Hjelmborg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Axel","family":"Skytthe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niels V.","family":"Holm","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirsten Ohm","family":"Kyvik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaare","family":"Christensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2019,9,23]]},"reference":[{"key":"S1832427419000720_ref4","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-018-0356-1"},{"key":"S1832427419000720_ref53","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1111\/j.1474-9726.2011.00775.x","article-title":"Genetic variation in TERT and TERC and human leukocyte telomere length and longevity: A cross-sectional and longitudinal analysis","volume":"11","author":"Soerensen","year":"2012","journal-title":"Aging Cell"},{"key":"S1832427419000720_ref18","doi-asserted-by":"publisher","DOI":"10.1097\/01.ede.0000165816.03286.c7"},{"key":"S1832427419000720_ref13","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1038\/nature15393","article-title":"A global reference for human genetic variation","volume":"526","author":"Auton","year":"2015","journal-title":"Nature"},{"key":"S1832427419000720_ref46","doi-asserted-by":"publisher","DOI":"10.1007\/s10519-015-9729-3"},{"key":"S1832427419000720_ref60","doi-asserted-by":"publisher","DOI":"10.1177\/1403494811399956"},{"key":"S1832427419000720_ref25","doi-asserted-by":"publisher","DOI":"10.1038\/nprot.2010.124"},{"key":"S1832427419000720_ref50","doi-asserted-by":"publisher","DOI":"10.1375\/twin.9.6.763"},{"key":"S1832427419000720_ref36","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-171163"},{"key":"S1832427419000720_ref61","doi-asserted-by":"publisher","DOI":"10.1177\/1403494811409654"},{"key":"S1832427419000720_ref11","doi-asserted-by":"publisher","DOI":"10.1097\/ALN.0000000000000957"},{"key":"S1832427419000720_ref22","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.EPI-13-0568"},{"key":"S1832427419000720_ref56","doi-asserted-by":"publisher","DOI":"10.3390\/genes9020078"},{"key":"S1832427419000720_ref42","doi-asserted-by":"publisher","DOI":"10.1177\/1403494810387965"},{"key":"S1832427419000720_ref38","doi-asserted-by":"publisher","DOI":"10.1007\/s00439-014-1458-9"},{"key":"S1832427419000720_ref48","doi-asserted-by":"publisher","DOI":"10.1017\/thg.2012.77"},{"key":"S1832427419000720_ref59","first-page":"1146","article-title":"Epigenetic drift in the aging genome: A ten-year follow-up in an elderly twin cohort","volume":"45","author":"Tan","year":"2016","journal-title":"International Journal of Epidemiology"},{"key":"S1832427419000720_ref2","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.EPI-15-0317"},{"key":"S1832427419000720_ref30","unstructured":"Lund, J.
