Ehlers-Danlos syndrome refers to a group of connective tissue disorders characterized by stretchy or “kneadable” skin, double jointedness, and delayed healing of skin wounds. In addition to these traits, individuals with the progeroid type have thin curly hair, sparse eyebrows and eyelashes, loose elastic skin on the face, and may also have uneven facial features. Although “progeroid” means "appearance similar to old age", individuals with progeroid Ehlers-Danlos syndrome do not actually have premature aging and are not expected to have a shortened life span. Other symptoms may include poor muscle tone, fragile bones from low bone mineral density, abnormal teeth, and infection of gums around the teeth. Children who are affected may have delayed growth, which can result in short stature as an adult (less than 152cm). Mild intellectual disabilities or learning disabilities have also been associated with this disorder.
