Classical Ehlers-Danlos Syndrome
Classical Ehlers-Danlos syndrome (EDS) is a genetic connective tissue disorder that is caused by defects in a protein called collagen. Common symptoms include skin hyperextensibility, abnormal wound healing, and joint hypermobility. More than 90% of people with classical EDS have mutations in COL5A1 or COL5A2, two genes which encode type V collagen. In rare cases, mutations in the gene encoding type I collagen, COL1A1 gene, may be found. The condition is inherited in an autosomal dominant manner. Treatment and management is focused on preventing serious complications and relieving associated symptoms.
