What is the life expectancy of Rett syndrome?
While it is known that Rett syndrome shortens lifespan, not much is known about specific life expectancy rates for people with Rett syndrome. It generally depends on the age when symptoms first begin and their severity. On average, most individuals with the condition survive into their 40s or 50s.
What causes Rett’s syndrome?
What causes Rett syndrome? Almost all cases of Rett syndrome are caused by a mutation (a change in the DNA) in the MECP2 gene, which is found on the X chromosome (one of the sex chromosomes). The MECP2 gene contains instructions for producing a particular protein (MeCP2), which is needed for brain development.
Is Rett’s syndrome autism?
Rett syndrome (RTT, MIM#312750) is a neurodevelopmental disorder that is classified as an autism spectrum disorder.
How is Rett’s disorder diagnosed?
Diagnosing Rett syndrome involves careful observation of your child’s growth and development and answering questions about medical and family history. The diagnosis is usually considered when slowing of head growth is noticed or loss of skills or developmental milestones occur.
What is the difference between Rett syndrome and autism?
Movement problems in people with Rett syndrome tend to be much more severe than those in autistic people. People with autism may have poor coordination or an awkward gait. But many girls with Rett syndrome are unable to walk, and as they get older they may develop rigidity or tremors.
What organs are affected by Rett syndrome?
Rett syndrome is a rare genetic neurological and developmental disorder that affects the way the brain develops, causing a progressive loss of motor skills and speech.
What do you need to know about Rett syndrome?

Rett syndrome is a rare genetic neurological disorder that occurs almost exclusively in girls and leads to severe impairments, affecting nearly every aspect of the child’s life: their ability to speak, walk, eat, and even breathe easily. The hallmark of Rett syndrome is near constant repetitive hand movements.

When does scoliosis occur in people with Rett syndrome?
Scoliosis is common with Rett syndrome. It typically begins between 8 and 11 years of age and increases with age. Surgery may be required if the curvature is severe. Irregular heartbeat. This is a life-threatening problem for many children and adults with Rett syndrome and can result in sudden death.
Are there any female carriers of Rett syndrome?
Most cases are spontaneous, which means the mutation occurs randomly. However, in some families of individuals affected by Rett syndrome, there are other female family members who have a mutation of their MECP2 gene but do not show clinical symptoms. These females are known as “asymptomatic female carriers.”
