[Up-to-date classification and multidisciplinary symptoms of Ehlers-Danlos syndromes].

In this review article, the authors summarize the clinical aspects of the novel classification of Ehlers-Danlos syndrome, which is a group of rare, hereditary connective tissue disorders. The leading symptom of the Ehlers-Danlos syndrome group is joint hypermobility, skin hyperextensibility and generalized tissue fragility. Ehlers-Danlos syndrome displays a high clinical and genetic heterogeneity and harbors many multidisciplinary properties. Certain subtypes only affect the quality of life, while other forms may lead to severe, even fatal vascular or intestinal complications. Last year, based on the data of various international genotype-phenotype correlation studies of large populations, a new classification of the syndrome's clinical subtypes was introduced. The novel international nosology of Ehlers-Danlos syndromes published in 2017 delineates 13 clinical subtypes, describes their genetic background and defines major and minor diagnostic criteria for each subtype. We gathered the complex, multidisciplinary symptoms of Ehlers-Danlos syndromes in a table to assist the diagnosis from a differential diagnostic point of view. In the clinical practice, the proper diagnosis of patients affected by the Ehlers-Danlos syndrome group is essential to give optimal clinical care and to prevent the development of severe complications.
