Prenatal three-dimensional sonographic images associated with Treacher Collins syndrome

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...

Prenatal Diagnosis of Treacher-Collins Syndrome Using Three-Dimensional Ultrasonography and Differential Diagnosis with Other Acrofacial Dysostosis Syndromes

Treacher-Collins syndrome (TCS) is a rare dominant autosomal anomaly resulting from malformation or disruption of the development of the first and second branchial arches. It is characterized by micrognathia, malar hypoplasia, and malformations of the eyes and ears. The prenatal diagnosis using two-dimensional ultrasonography (2DUS) is characterized by identification of facial malformations tog...

Samjforum Case Report Penile Agenesis Associated with Treacher Collins Syndrome

Penile agenesis or aphallia is a rare congenital anomaly occurring with a frequency of 1:10 -1:30 million newborns. Fewer than 100 cases have been reported worldwide. Associated urogenital malformations and the presence of oligohydramnios with pulmonary hypoplasia determine the infant's viability. Extra-urogenital anomalies have been described in the cardiovascular, gastro-intestinal and muscul...

Ear surgery in Treacher Collins syndrome.

The autosomal dominant hereditary Treacher Collins syndrome manifests itself phenotypically in dysmorphogenesis of particularly the first, but also the second branchial arch system. Consequently, 50% of patients with Treacher Collins syndrome have a congenital, generally pure conductive hearing loss resulting from a major or minor ear anomaly. The outcome of surgery to improve patients' hearing...
