Ehlers-Danlos Syndrome (EDS) Gene Panel
Dr. rer. nat. Karin Mayer
Ehlers-Danlos syndrome (EDS) is a clinically and genetically heterogeneous group of connective tissue disorders, which is characterized by hyperelastic skin, tissue fragility, joint hypermobility and various skeletal, cardiovascular, and gastrointestinal symptoms as well as involvement of the lungs and eyes. Based on clinical, biochemical and molecular genetic data as well as inheritance (autosomal dominant, autosomal recessive, or X-linked) EDS can be divided into 13 subtypes. According to the Villefranche classification, these groups are subdivided into 6 main types, where mutations in genes for fibrillar collagens or enzymes of the collagen metabolism are present. In the last few years more and more new EDS types were genetically and biochemically identified and characterized, which has led to a better understanding of the EDS pathogenesis, going beyond the collagen metabolism. Since clinical distinction of the different EDS types is often difficult, genetic diagnostics using next generation sequencing (NGS) can facilitate diagnosis.
All coding exons and their flanking intronic sequences from the genes in the Ehlers Danlos gene panel are analyzed either by Sanger sequencing or by next generation sequencing (NGS).
