Symptoms
RTT is caused by mutations in the gene MeCP2, found on the X chromosome. MeCP2 is called a "transcriptional repressor" because it codes for a protein that controls the expression of other genes.
Causes
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.
Prevention
Interesting Facts about Rett Syndrome. -Rett syndrome is a debilitating neurological disorder that predominantly affects females. -Female children with Rett syndrome are born normal until about the age of one-three years old. -Rett syndrome is caused by a single gene mutation that leads to underproduction of an important brain protein.
Complications
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 type of Morph is Rett syndrome?

What causes Rett syndrome?
Almost all cases of Rett syndrome are caused by mutations in the MECP2 (methyl CpG binding protein 2) gene , which provides instructions for making a protein of the same name. The MECP2 protein is involved in regulating the activity of other genes by modifying the structure of chromatin, the bundle of protein and DNA that makes up chromosomes. By making changes to chromatin, MECP2 controls which genes are “turned on” or “turned off,” which has substantial effects on cellular activity.

Do boys survive Rett syndrome?
Without a functional version of MECP2, boys typically do not survive early infancy.
Is Rett syndrome inherited?
Although Rett syndrome is a genetic disease, less than 1% of cases are inherited. The remainder of cases are caused by de novo (new) mutations. The MECP2 gene is located on the X-chromosome, which is one of the chromosomes whose inheritance helps determine biological sex. Females have two copies of the X-chromosome.
What is the hallmark of Rett syndrome?
The hallmark of Rett syndrome is near constant repetitive hand movements. 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. Rett syndrome is caused by mutations on the X chromosome on a gene called MECP2.

What Causes Rett Syndrome?
- Rett syndrome is a rare genetic disorder. Classic Rett syndrome, as well as several variants (atypical Rett syndrome) with milder or more-severe symptoms, occur based on several specific genetic changes (mutations). The genetic changes that cause Rett syndrome occur randomly, usually in the MECP2 gene. Very few cases of this genetic disorder are in...
Other Genetic Causes of Rett
- Rett syndrome is rare. The genetic changes known to cause the disease are random, and no risk factors have been identified. In a very small number of cases, inherited factors — for instance, having close family members with Rett syndrome — may play a role.
Inheritance of Rett Syndrome
