General Discussion Back to top
Treacher Collins syndrome is a rare genetic disorder characterized by distinctive abnormalities of the craniofacial area due to underdevelopment (hypoplasia) of certain bones of the head including the cheekbones and nearby structures (zygomatic complex and the jaw. The specific symptoms and physical characteristics associated with Treacher Collins syndrome may vary greatly from case to case. Craniofacial abnormalities tend to involve the cheekbones, jaws, mouth, ears, and/or eyes. In addition to the various facial abnormalities, affected individuals may have malformations of the external ears and middle ear structures and eye (ocular) abnormalities including an abnormal downward slant to the opening between the upper and lower eyelids (palpebral fissures). Affected individuals may develop hearing loss and breathing (respiratory) difficulties. In some cases, affected individuals may have mild symptoms and may go undiagnosed. In approximately 40 percent of cases, Treacher Collins syndrome has autosomal dominant inheritance. However, in about 60 percent of cases, a positive family history is not found. These cases likely represent new genetic changes (mutations) that occur randomly, with no apparent cause (sporadic).
