We are delighted to invite you to the Scientific Meeting on the Rarer Types of Ehlers-Danlos Syndromes, in Tokyo, Japan on 18–19 November 2019.

Scientific Meeting on the Rarer Types of Ehlers-Danlos Syndromes is a professional scientific meeting on Ehlers-Danlos syndrome (EDS) for healthcare providers and researchers, in which cutting-edge research on clinical advances and the molecular and pathogenic mechanisms of mainly rare types of EDS is discussed. We offer a high-quality scientific program with the general theme, “Rarer types of EDS: from genetics to management.” World-leading invited speakers will talk on the newest medical and scientific achievements on proteoglycan defect-related EDS, TNXB-related classical-like EDS, dermatosparaxis EDS, and periodontal EDS, also on the current topics about major molecularly-confirmed types, classical EDS, and vascular EDS. The meeting welcomes abstracts for oral or poster presentation on any relevant topics about rarer types of EDS, also classical or vascular type, including clinical investigation on EDS (e.g. genotype/phenotype correlations; natural history and disease manifestations), molecular breakthrough on EDS (e.g. novel gene for EDS), pathophysiology on EDS (e.g. novel biochemical, pathological, or physiological mechanisms in EDS typically using patients’ samples), animal models on EDS (e.g. KO mice), and therapeutic challenges for EDS (e.g. clinical study; basic investigation).

We strongly encourage clinicians and researchers with an interest in the Ehlers-Danlos syndromes to attend this meeting. We expect 250 delegates and key opinion leaders in the field from around the world to attend. The multidisciplinary nature of the conference provides an opportunity to talk to specialists from many different fields including basic scientists, geneticists, internists, orthopedic and vascular surgeons, dentists, pediatricians, physiotherapists, genetic counselors, nurses, representatives of patient support groups, and many others working with Ehlers-Danlos syndromes.

Highlights include:

  • An exciting program of invited speakers and lectures featuring some of the leading experts in the field;
  • Presentation of talks chosen from submitted abstracts;
  • A well-attended poster session with local gastronomic treats.

We hope that you will join us from all over the world, especially from Asia, for an exciting meeting with enthusiastic discussions about cutting-edge clinical medicine and basic science related to the Ehlers-Danlos syndromes. Come and participate in an interactive meeting in cool Tokyo!

Tokyo, Japan’s busy capital, mixes the ultramodern and the traditional, from neon-lit skyscrapers to historic temples. The opulent Meiji Shinto Shrine is known for its towering gate and surrounding woods. The Imperial Palace sits amid large public gardens. The city’s many museums offer exhibits ranging from classical art (in the Tokyo National Museum) to a reconstructed kabuki theater (in the Edo-Tokyo Museum).


Shinjuku (新宿) is one of the 23 city wards of Tokyo, but the name commonly refers to just the large entertainment, business and shopping area around Shinjuku Station.

Shinjuku Station is the world’s busiest railway station, handling more than two million passengers every day. It is served by about a dozen railway and subway lines, including the JR Yamanote Line. Shinjuku is also one of Tokyo’s major stops for long-distance highway buses. A large bus terminal, named Busta Shinjuku, is conveniently located on top of the railway station.

West of the station is Shinjuku’s skyscraper district, home to many of Tokyo‘s tallest buildings, including several premier hotels and the twin towers of the Metropolitan Government Office, whose observation decks are open to the public for free.

Northeast of the station lies Kabukicho, Japan’s largest and wildest red light district, while department stores, subterranean malls and electronic shops surround Shinjuku Station on all four sides, including the redeveloped Southern Terrace.
