   Treacher Collins syndrome (also known as Franceschetti-Zwahlen-Klein syndrome or mandibulofacial dysostosis) is a rare genetic disorder characterized by craniofacial deformities. Treacher Collins syndrome is found in 1 in 10,000 births. The typical physical features include downward slanting eyes, micrognathia (a small lower jaw), conductive hearing loss, underdeveloped zygoma, drooping part of the lateral lower eyelids, and malformed or absent ears.
   This condition is a result of a defect of the first arch during development.
