If you’ve heard the phrase “Rett’s autism,” you might be wondering what it really means. Rett syndrome is a rare genetic condition, most often seen in girls, that can look a lot like autism at first. Kids may struggle with communication, social skills, and repetitive movements. But Rett syndrome is not autism — it’s a separate condition with its own causes and challenges.

Rett syndrome is caused by a mutation in the MECP2 gene. Unlike autism, which has no single known cause, Rett usually shows up when a child begins to lose skills they once had, such as talking or walking. That’s one of the biggest differences from autism, where developmental differences are usually present early on.

Here’s how Rett and autism can look similar:

• Trouble with social interaction

• Limited or lost speech

• Repetitive hand movements, like wringing or clapping

Even though there’s no cure, therapies like ABA can make a big difference in helping children build communication and daily living skills.
