Rett Syndrome Awareness Month by CheckRare Staff| Published on: Oct 1, 2026

https://checkrare.com/rett-syndrome-awareness-month/ Rett syndrome is a neurodevelopmental condition that primarily affects girls. People with the disease appear to have normal psychomotor development during the first 6 to 18 months of life before developing severe problems with language and communication, learning, coordination, and other brain functions. Additional signs and symptoms may include repetitive, stereotypic hand movements, fits of screaming and inconsolable crying, autistic features, panic-like attacks, teeth grinding, episodic apnea and/or hyperpnea, gait ataxia and apraxia, tremors, seizures, and slowed head growth. Classic Rett syndrome is most commonly caused by genetic changes in the MECP2 gene.
