What is Rett syndrome?

Rett syndrome is a non-inherited genetic neurological disorder, caused by a mutation of the MECP2 gene, that occurs almost exclusively in girls.

Rett syndrome leads to severe impairments, affecting nearly every aspect of the child’s life: their ability to speak, walk, eat, and even breathe easily.

The hallmark of Rett syndrome is near constant repetitive hand movements while awake. Girls with Rett are cognizant and aware of their surroundings. They have the ability to express a wide spectrum of moods and emotions, but it is very difficult for them to communicate.

Rett affects about 1 in 10,000 girls making it more common than A.L.S (Lou Gehrig’s disease).
