Semmelweis University is a research-led medical school in Budapest, Hungary founded in 1769. Its 250 years of tradition and unique focus on health care made it one of the leading universities of medicine and health sciences in Hungary and the Central European region.[1] With its six faculties and doctoral school it covers all aspects of medical and health sciences ranging from pathology through genetics, paediatrics, pharmacy, dentistry, dietetics, physiotherapy, nursing, health policy and management to conductor training.


The first Hungarian Twin Registry was established in Budapest in 1970 through the mandatory reporting of multiple-births. In the 1980s a second, volunteer adult registry was also founded. Unfortunately, both registries ceased to exist in the 1990s. Efforts started in 2006 to revive a Hungarian twin registry. The team spearheading this effort reports here on this progress. Currently, the voluntary Hungarian Twin Registry turned to population based twin registry, which consists of 10k  twin pairs and multiplets. Current research focuses on cardiovascular and respiratory health and yielded multiple awards and publications. Efforts are on the way to expand into social, psychological, and obesity studies.
