Ehlers-Danlos syndrome (EDS), classic type, is an inherited connective tissue disorder characterized by skin hyperextensibility, abnormal wound healing, and joint hypermobility. The classic type is made up of two previously designated subtypes (EDS type I and EDS type II) which represent a continuum of clinical features. About 50% of people with EDS, classic type have mutations in COL5A1 or COL5A2, two genes which encode type V collagen. The condition is inherited in an autosomal dominant manner.[1]
