Question: What Is Rett Syndrome Wikipedia?

What does Rett syndrome mean?

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 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.

What part of the body does Rett syndrome affect?

Rett syndrome is a severe condition of the nervous system. It is almost only seen in females, and affects all body movement. Rett syndrome may cause speech problems (such as inability to learn to speak, or loss of speech), difficulty walking or loss of the ability to walk, and loss of purposeful hand use.

Can Rett syndrome be detected before birth?

Prenatal diagnosis for Rett syndrome involves DNA testing to find out whether the developing fetus has a mutation in the MECP2, CDKL5, and FOXG1 genes. Rett syndrome mostly occurs as a result of a de-novo mutation, meaning that the defect is not inherited from the parents but appears spontaneously.

Can a boy have Rett syndrome?

Rett syndrome is a genetic neurodevelopmental disorder that almost exclusively affects females and is very rare in males. Rett syndrome is caused by mutations in the MECP2 gene located on the X chromosome.

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.

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.

What is the life expectancy of a person with 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.

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 can I help someone with Rett syndrome?

Treatments that can help children and adults with Rett syndrome include:Regular medical care. Management of symptoms and health problems may require a multispecialty team. … Medications. … Physical therapy. … Occupational therapy. … Speech-language therapy. … Nutritional support. … Behavioral intervention. … Support services.

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.

Who has Rett syndrome?

Rett syndrome is a rare genetic neurological disorder that affects 1 in 10,000 females (and even more rarely in males) and begins to display itself in missed milestones or regression at 6-18 months.

Where is Rett Syndrome most common?

Rett syndrome occurs almost exclusively in girls. The incidence of Rett syndrome in the United States is estimated to be 1 in 10,000 girls by age 12.

Does Rett syndrome affect intelligence?

One in 10,000 females suffers from Rett Syndrome, leaving them aware and alert but often without the ability to express themselves in any way. Without the ability to communicate through speech or hand movement, Rett Syndrome patients have not been able to demonstrate their intellectual abilities.

How does Rett syndrome affect the family?

The chance of having more than one child with Rett syndrome is very small. If a family has an affected daughter and no other affected relatives, the recurrence risk is much less than 1% for the family and children.
