Addison-Treacher Collins syndrome
Overview
Addison-Treacher Collins syndrome is a genetic condition that affects a person's physical appearance. People with this syndrome often have facial features that are different from those of others, such as droopy eyelids, underdeveloped cheekbones, and a small jaw. These differences can vary in severity from person to person.
In addition to facial abnormalities, individuals with Addison-Treacher Collins syndrome may also have hearing loss, cleft palate, and problems with their teeth. The syndrome is caused by a mutation in a specific gene that is responsible for the development of facial bones and tissues. This mutation can be inherited from a parent or can occur spontaneously. Treatment for Addison-Treacher Collins syndrome focuses on managing the physical symptoms and may include surgery to correct any facial abnormalities or hearing aids to help with hearing loss.
