Treacher Collins Syndrome

Treacher Collins syndrome (TCS) is a genetic disease that alters the development of bones and other tissues in the face, and presents variable expressivity. At least three genes TCOF1, POLR1D, and POLR1C were recognized to be at the origin of this syndrome which may be inherited through either an autosomal dominant or autosomal recessive pattern. TCS changes can be divided into otological, opht...

A Case of Treacher Collins Syndrome

Treacher Collins syndrome (TCS) is an autosomal dominant disorder of craniofacial development with an incidence of 1/50,000 live births. Mutations of the TCOF1 gene have been found to be responsible for most cases of this mandibulofacial disorder. Here we report TCS in an individual who has a heterozygous c.1021_1022delAG deletion in exon 7 of the TCOF1 gene (NG_011341.1). This is the second Tu...

Orofacial features of Treacher Collins syndrome.

Treacher Collins syndrome (TCS) is a rare autosomal dominant disorder of craniofacial development. Major features include midface hypoplasia, micrognathia, microtia, conductive hearing loss, and cleft palate. The present study is on the orofacial features of 7 Brazilian patients with sporadic TCS aged 4 to 38 years. All patients presented the typical down-slanting palpebral fissures, colobomas,...
