Information about Rett syndrome


Rett syndrome is a rare genetic disorder that mostly affects females. The disease is characterized by normal early development, followed by slowed growth and a loss of motor control. Learn more about the disease here.


Most cases are caused by a mutation in the MECP2 gene. Scientists have identified mutations in CDKL5 and FOXG1 genes in those who have atypical or congenital Rett. Learn more about what causes the disease here.


Rett syndrome is associated with problems in cognitive, sensory, emotional, and motor skills, and across the nervous system that controls involuntary (or autonomic) functions. Learn more about the symptoms of the disease here.
