Overview
Treacher Collins Syndrome is a genetic, craniofacial birth defect which primarily
affects the size and shape of the ears, eyelids, cheek bones, and upper and lower
jaws. It occurs in approximately 1 of 10,000 births, making it a rare condition. The
extent of severity varies from one affected individual to another. Some individuals
have very subtle features of this syndrome that may go unrecognized, while others
manifest more severe features that are noticed immediately. Most individuals with
Treacher Collins Syndrome have normal intelligence, and are therefore able to attend
regular schools. No evidence has been found that these individuals have a lower life
expectancy than those who are not affected by the syndrome. Alternative medical
names for this syndrome include "Mandibulofacial Dysostosis" and "Franceschetti-
Klein Syndrome".
