Treacher Collins Syndrome (TCS)
Other names: TCS; TCOF; Treacher Collins-Franceschetti Syndrome; Mandibulofacial dysostosis; MFD1
What is Treacher Collins Syndrome?
Treacher Collins Syndrome (TCS) is a rare genetic disorder that affects the development of the bones and soft tissues in the face. Some of the common features of Treacher Collins Syndrome include underdeveloped cheekbones, a small mouth and jaw, ear abnormalities, downward-slanting eyes, and cleft palate. These features may vary in severity, and can affect both appearance and function – including breathing, feeding, and hearing.
Treacher Collins Syndrome may be caused by mutations in the TCOF1, POLR1C, or POLR1D genes, which play an important role in the early development of facial bones and tissues. Mutations in these genes can disrupt the normal development of the bones and tissues, resulting in the characteristic features of TCS. When mutations in the TCOF1 or POLR1D genes are responsible for the condition, it is inherited in an autosomal dominant manner, which means that an individual only needs to inherit one copy of the mutated gene from either parent to develop the condition. When a mutation in the POLR1C gene is responsible for the condition, it is inherited in an autosomal recessive manner, which means that an individual needs to inherit a copy of the mutated gene from both parents to develop the condition. In some cases, a person may develop Treacher Collins Syndrome even if they do not have a family history of the condition due to newly arising genetic mutations.
Treatment for Treacher Collins Syndrome may involve surgery to reconstruct facial bones, improve hearing or breathing, and correct cleft palate. People with Treacher Collins Syndrome may also need other supportive measures such as speech and language therapy and hearing aids. Genetic counseling may also be recommended for individuals and families affected by Treacher Collins Syndrome.
