What Is Rett’s Autism? Understanding the Basics

What is Rett’s autism? Rett syndrome, once considered part of the autism spectrum, is a rare genetic neurodevelopmental disorder that primarily affects girls. Unlike typical autism, Rett syndrome has a clear genetic cause and a distinct pattern of development.


Key Facts About Rett Syndrome

Rett syndrome typically appears between 6 and 18 months of age after a period of seemingly normal development. Children begin to lose skills they had gained, including speech, purposeful hand use, and social interaction. This regression often includes autistic-like behaviors such as limited eye contact and reduced social engagement.


The disorder is caused by mutations in the MECP2 gene on the X chromosome. These genetic changes disrupt brain development and function, leading to symptoms like repetitive hand movements, difficulty walking, seizures, and intellectual disability.




How Is Rett’s Different from Autism?

Although Rett syndrome shares some features with autism, it is no longer classified as an autism spectrum disorder. It has a defined genetic cause and a unique clinical course involving stages of loss and partial regain of social skills.
