Treacher Collins Syndrome 1; Tcs1

Description

Treacher Collins syndrome is a disorder of craniofacial development. The features include antimongoloid slant of the eyes, coloboma of the lid, micrognathia, microtia and other deformity of the ears, hypoplastic zygomatic arches, and macrostomia. Conductive hearing loss and cleft palate are often present (Dixon, 1996). Genetic Heterogeneity of Treacher Collins SyndromeTreacher Collins syndrome-2 (TCS2 ) is caused by mutation in the POLR1D gene (OMIM ) on chromosome 13q12. Treacher Collins syndrome-3 (TCS3 ) is caused by mutation in the POLR1C gene (OMIM ) on chromosome 6p21.
