** **Ehlers-Danlos Syndrome** is a group of genetic disorders that affect the body's connective tissue, leading to extremely flexible joints, fragile skin, and other complications. **CONTENT:** ### Overview Ehlers-Danlos Syndrome (EDS) is a rare genetic disorder that affects the body's connective tissue, which provides support and structure to various organs, joints, and other tissues. This condition is characterized by extremely flexible joints, fragile skin, and other complications that can impact a person's quality of life. EDS is often divided into 13 subtypes, each with distinct symptoms and characteristics. While the exact cause of EDS is still not fully understood, it is believed to be related to mutations in genes that code for collagen, a protein essential for connective tissue. People with EDS may experience a range of symptoms, including joint hypermobility, skin hyperextensibility, and tissue fragility. Joint hypermobility can lead to joint instability and dislocations, while skin hyperextensibility can cause skin tears and bruising. Tissue fragility can result in easy bruising, poor wound healing, and gastrointestinal complications. In addition to these physical symptoms, people with EDS may also experience fatigue, anxiety, and depression. ### History/Background The first reported case of EDS was in 1901 by the dermatologist Edward Henry Ehlers. However, it was not until 1936 that the British dermatologist George Donati and the American dermatologist Harry Beighton independently described the condition in more detail. Since then, research has led to a greater understanding of EDS and the development of diagnostic criteria. In 1996, the International Classification of the Ehlers-Danlos Syndromes was established, which categorized the condition into 11 subtypes. In 2017, two new subtypes were added, bringing the total to 13. ### Key Information EDS is a genetic disorder, meaning it is passed down from parents to children through genes. While the exact cause of EDS is still not fully understood, it is believed to be related to mutations in genes that code for collagen. Collagen is a protein essential for connective tissue, and mutations in these genes can lead to the production of abnormal collagen. This can result in the symptoms associated with EDS. There are several subtypes of EDS, each with distinct symptoms and characteristics. The most common subtypes include: * Classical EDS (cEDS): characterized by skin hyperextensibility, joint hypermobility, and tissue fragility. * Hypermobile EDS (hEDS): characterized by joint hypermobility, musculoskeletal pain, and gastrointestinal complications. * Vascular EDS (vEDS): characterized by fragile blood vessels and a high risk of rupture. ### Significance Ehlers-Danlos Syndrome is a significant condition that affects the lives of thousands of people worldwide. While it is a rare disorder, it can have a profound impact on a person's quality of life. People with EDS may experience chronic pain, fatigue, and anxiety, which can impact their ability to work, attend school, and engage in daily activities. In addition, EDS can increase the risk of complications such as joint dislocations, skin tears, and gastrointestinal problems. ### INFOBOX: - **Name:** Ehlers-Danlos Syndrome - **Type:** Genetic disorder - **Date:** 1901 (first reported case) - **Location:** Worldwide - **Known For:** Extremely flexible joints, fragile skin, and tissue fragility ### TAGS: Genetic disorder, connective tissue, joint hypermobility, skin hyperextensibility, tissue fragility, Ehlers-Danlos Syndrome, classical EDS, hypermobile EDS, vascular EDS, rare disorder, chronic pain, fatigue, anxiety, gastrointestinal complications.
