How old is the oldest person with Rett syndrome?

At what age is Rett syndrome usually diagnosed?
Rett syndrome is usually recognized in children between 6 to 18 months as they begin to miss developmental milestones or lose abilities they had gained.
How is Rett syndrome transmitted?
A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition. Males with mutations in the MECP2 gene often die in infancy.
How many cases of Rett syndrome are there?
Researchers don’t know exactly how many people have Rett syndrome. Current estimates suggest that this condition occurs in about 1 in every 10,000 girls worldwide. In the United States, the estimate is that Rett syndrome affects between 1 in 10,000 and 1 in 22,000 females.
Does Rett syndrome affect lifespan?
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 does Rett syndrome stand for?
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. This disorder primarily affects girls.
What is the cause of Rett 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.
Who discovered Rett syndrome?
Rett syndrome was first described in the medical literature by an Austrian physician named Andreas Rett in 1960s.
What percent of the population has Rett syndrome?
Rett syndrome is estimated to affect one in every 10,000 to 15,000 live female births and in all racial and ethnic groups worldwide.
Is Rett syndrome a form of autism?
It is categorized as an autism spectrum disorder, but, unlike most forms of autism, Rett syndrome has a clear-cut cause—a mutation in a protein known as MeCP2.
What is another name for Rett syndrome?

What is the life expectancy of a girl with Rett syndrome?
Life expectancies are not well studied, although survival at least until the mid-20s is likely. The average life expectancy for girls may be mid-40s. Death is often related to seizure, aspiration pneumonia, malnutrition, and accidents.
