About Rett Syndrome

Rett Syndrome is a post-natal neurological disorder, which most often affects little girls, around the age of 12-18 months.

Estimated to affect 1:10,000 live female births, the disorder is rarely seen in males. Most people with Rett Syndrome are unable to speak, walk or use their hands. Breathing problems, feeding tubes, seizures, anxiety, gastrointestinal and orthopaedic issues are common. Research has shown that people with Rett do not have brain damage. They know and understand much more than their bodies allow them to show – but they are locked in, trapped by a body that cannot obey signals from their brain.

What causes Rett?

Rett Syndrome is most often caused by mutations on a gene called MECP2 on the X chromosome. The gene makes a protein which everyone needs for their brains to function properly, but people with Rett Syndrome do not have enough of this protein. In 2007, researchers at Edinburgh University proved that a cure for Rett Syndrome is possible. The scientists did this by using genetic engineering to replace the missing protein in a mouse model. These experiments showed that when the protein is replaced at the right level, the symptoms of Rett Syndrome go away. Gene therapy is one way that the protein can be replaced and human clinical trials are due to start in 2019.

Newly diagnosed?

If your child has just been diagnosed with Rett Syndrome or your doctor has recommended testing for Rett, you may have many questions. Find out more about how the condition is diagnosed and the answers to some common questions here.

What are the symptoms?

There are many symptoms of Rett Syndrome. Some signs appear in the first 6-18 months of the child’s life, but some appear between the ages of 1 and 4. Although very rare, boys can also be affected by the disease.

Diagnosing Rett Syndrome

Diagnosing Rett Syndrome is still a clinical process despite the genetic testing which is now available. A doctor, geneticist or psychologist will observe your child then make a clinical diagnosis based on the symptoms which are present.
