What is Rett Syndrome?

Rett syndrome is a rare genetic neurological disorder that leads to severe impairments, affecting nearly every aspect of life. Rett particularly affects speech, purposeful hand use, and coordination, leaving individuals understanding more than they can communicate. Caused by a gene mutation, Rett is first recognized in infancy and occurs primarily in girls, with a growing number of males now being identified.
