People with EDS have some degree of joint looseness; fragile, small blood vessels; abnormal scar formation and wound healing; and soft, velvety skin that stretches excessively but returns to normal after being pulled. Some forms can cause problems with the eyes and spine. EDS can also lead to weak internal organs, including the uterus, intestines, and large blood vessels. Mutations in several different genes are responsible for varying symptoms in the several types of EDS. In most cases, the genetic defect involves collagen, the major protein-building material of bone.Contents: Chapter 1: National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Information * Chapter 2: Genetics Home Reference Information * Chapter 3: NIAMS Background Material * Chapter 4: Clinical Trials * Guide to Leading Medical Websites - Internet Resources for Medical and Health InformationThis edition includes our exclusive Guide to Leading Medical Websites with updated links to 81 of the best sites for medical information, which let you quickly check for updates from the government and the best commercial portals, news sites, reference/textbook/non-commercial portals, and health organizations.
