What are the signs and symptoms of Ehlers-Danlos syndrome, progeroid type? 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. The Human Phenotype Ontology provides the following list of signs and symptoms for Ehlers-Danlos syndrome, progeroid type. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
