Symptoms
Jason DelCollo, DO, is board-certified in family medicine and on the faculty of Philadelphia College of Osteopathic Medicine. Treacher Collins syndrome, also known as mandibulofacial dysostosis, is a rare disease that affects facial bone development, causing major facial deformities.
Causes
This can make it extremely hard for a patient with Treacher Collins syndrome to speak, which is when speech therapy can become an important piece of treatment. A speech-language pathologist can help find deficiencies in the patient's speech by interviewing and assessing the individual.
Complications
In patients with Treacher Collins syndrome, surgical intervention often begins with a focus on preserving the airways. One of the procedures that can be done to do this is a rhinoplasty. Rhinoplasties are commonly referred to as nose jobs and are usually used by individuals to improve their appearance.

What are the abnormalities of TCS?
The abnormalities of TCS are typically symmetric (almost identical on both sides of the face) and are present at birth (congenital). Speech and language development can be compromised by hearing loss, cleft palate or jaw and airway problems.
What is TCS caused by?
TCS is primarily caused by changes (mutations) in the TCOF1 gene, but is also associated with mutations in the POLR1B, POLR1C or POLR1D genes. In the case of TCOF1 and POLR1B, the mode of inheritance is autosomal dominant, while for POLR1C it is autosomal recessive.
What is the name of the disorder that causes the head to slant downwards?
Treacher Collins syndrome (TCS) is a rare genetic disorder characterized by distinctive abnormalities of the head and face. Craniofacial abnormalities tend to involve underdevelopment of the zygomatic complex, cheekbones, jaws, palate and mouth which can lead to breathing and feeding difficulties. In addition, affected individuals may also have malformations of the eyes including a downward slant of the opening between the upper and lower eyelids (palpebral fissures) and anomalies of external and middle ear structures, which may result in hearing loss. Brain and behavioral anomalies such as microcephaly and psychomotor delay have also been occasionally reported as part of the condition. The specific symptoms and physical characteristics associated with TCS can vary greatly from one individual to another. Some individuals may be so mildly affected as to go undiagnosed, while others may develop serious, life-threatening complications. TCS is primarily caused by changes (mutations) in the TCOF1 gene, but is also associated with mutations in the POLR1B, POLR1C or POLR1D genes. In the case of TCOF1 and POLR1B, the mode of inheritance is autosomal dominant, while for POLR1C it is autosomal recessive. In contrast, both autosomal dominant and recessive mutations in POLR1D have been reported in association with TCS.
How many people have a TCOF1 mutation?
Approximately 80% of individuals have an identifiable mutation of the TCOF1 gene. Furthermore, genetic confirmation of a TCOF1, POLR1B, POLR1C, or POLR1D mutation can be detected before birth (prenatally) by amniocentesis and chorionic villus sampling if a mutation has been identified in an affected family member.
How many people are affected by TCS?
Affected Populations. TCS affects males and females in equal numbers. The prevalence is estimated to be between 1 in 10,000-50,000 individuals in the general population. Some mildly affected individuals may go undiagnosed, making it difficult to determine the disorder’s true frequency in the general population.
