What Is The Cause Of Rett Syndrome?

Why is Rett syndrome only found in females?

Why is Rett syndrome usually only found in girls.

Females have two copies of the X chromosome and males have one X and one Y chromosome.

The MECP2 gene is found on the X chromosome, so females born with one normal and one changed copy of the MECP2 gene usually develop the symptoms of Rett syndrome..

How is Rett Syndrome Detected?

Rett syndrome is confirmed with a blood test to identify the MECP2 mutation. However, since the MECP2 mutation is also seen in other disorders, a Rett syndrome (RTT) diagnosis requires either the presence of the MECP2 mutation or fulfillment of the diagnostic criteria or both.

How does Rett syndrome affect a person’s life?

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.

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.

Is Rett syndrome reversible?

These experiments suggest that Rett syndrome is not, as previously suspected, a strictly neurodevelopmental disorder. It is possible that the symptoms associated with the disorder could also be reversible in humans—even those with well-developed disease.

Can Rett syndrome be prevented?

There’s no known way to prevent Rett syndrome. In most cases, the genetic mutation that causes the disorder occurs spontaneously.

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.

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.

Is Rett syndrome an intellectual disability?

Rett syndrome was first described in Vienna in 1966 [33]. The disorder is a severe neurodevelopmental disorder characterized by intellectual disability (ID), poor muscle tone, reduced brain growth, scoliosis, and cardiorespiratory dysregulation and caused by mutation in the MECP2 coding region [17], [32].

How old is the oldest person with Rett syndrome?

Coenraads said girls with Rett syndrome typically live to adulthood and middle age, and the oldest person she knew of who had Rett died at 77.

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.

Can Rett syndrome be detected prenatally?

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.

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.

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.
