| Outline of Final Research Achievements |
Ehlers-Danlos syndrome (EDS) is a heterogeneous group of heritable connective tissue disorders, the hallmarks of which are skin hyperextensibility, joint hypermobility, and tissue fragility involving the skin, ligaments, joints, blood vessels, and internal organs. It was classified into six major types, and additional forms of EDS have also been identified in association with molecular and biochemical abnormalities. However, we sometimes experience patients who cannot be categorized into any previous forms of EDS. In this study, we aimed to identify new forms of EDS through detailed and comprehensive clinical assessment and next-generation sequencing-based genetic screening. As a result, we have successfully identified several new forms of EDS, including a severe subtype of classical type EDS presenting with marked skin hyperextensibility and fragility as well as severe progressing kyphoscoliosis from infancy, which is caused by COL5A2 mutations.
