What is Treacher Collins Syndrome?

Treacher Collins syndrome is a genetic condition that causes abnormalities of the bones and tissues of the face, head, and ears. The cheekbones, eye sockets, and jaw do not properly develop during pregnancy. The syndrome presents with variable levels of severity, being almost unnoticeable or pronounced. People with this disorder may have problems with sight, hearing, breathing, or cleft palates. Treacher Collins syndrome does not affect mental health.

Diagnosis of Treacher Collins Syndrome

It is usually easy to diagnose Treacher Collins syndrome because individuals with this condition have specific facial characteristics, although some other conditions cause similar physical attributes. X-rays and other techniques can confirm the diagnosis.Sometimes, diagnosis may include identifying a milder form of the disease in the child’s parents. If the parents carry the mutated gene, they have a 50% chance of having another child with Treacher Collins syndrome. In pregnancy, ultrasonography may be able to pick up various abnormalities in the head and potentially diagnose the condition before the child is born.

Causes of Treacher Collins syndrome

A genetic mutation causes Treacher Collins syndrome. Around 40% of those with Treacher Collins syndrome inherit it from their parents. 60% have a new genetic mutation. A mutation to the TCOF1 gene is the most common cause, accounting for around 90% of cases. The POLR1C and POLR1D genes may also mutate. Some researchers think these genetic mutations reduce the production of ribosomal RNA, which may lead to cell death in the tissues of the bones and face.

Treatment of Treacher Collins Syndrome

Multiple health professionals may be involved in the treatment of individuals with Treacher Collins syndrome. Doctors will monitor and treat newborns to make sure their airways are functioning properly. This may require surgical intervention such as opening the windpipe. If hearing is affected, the child may require a hearing aid or speech therapy in the future. Surgery can rebuild or adjust abnormally developed areas such as the roof of the mouth, skull, cheekbones, eyelids, and jaw. The type of surgery required will determine the age at which the child undergoes the procedure.

The Prognosis for Treacher Collins Syndrome

The prognosis for people with Treacher Collins syndrome depends on how their symptoms affect them. Severe cases can lead to death in babies due to problems with the airways. However, in the majority of cases, Treacher Collins syndrome does not affect a person’s life expectancy.

Prevalence of Treacher Collins Syndrome

In Europe, one in 50,000 people is affected by Treacher Collins syndrome. Internationally, this rate varies from one in 10,000 to one in 50,000. Some sources say the condition could affect as many as one in 70,000 people. Sometimes, individuals with a mild form of the syndrome go undiagnosed, affecting these statistics.

History of Treacher Collins Syndrome

Treacher Collins syndrome was first described by Edward Treacher Collins (1982-1932), a British surgeon and ophthalmologist who wrote about the features of the condition in 1900.
