What gene is affected by Rett syndrome?

Most Rett syndrome cases are caused by identifiable mutations of the MECP2 gene on the X chromosome and can present with a wide range of disability ranging from mild to severe.

Is there genetic testing for Rett syndrome?

Your child’s doctor may also order a genetic DNA blood test to support the diagnosis of Rett syndrome. This genetic test may detect a disease-causing change within the MECP2 gene. Most people with a clinical diagnosis of Rett syndrome (80 to 97 percent) have a change in this gene.

Who carries the gene for Rett syndrome?

Because the mutated gene that causes Rett syndrome is located on the X chromosome, females have twice the opportunity to develop a mutation in one of their X chromosomes. Females with Rett syndrome usually have one mutated X chromosome and one normal X chromosome.

Is Rett syndrome a form of autism?

Rett syndrome (RTT, MIM#312750) is a neurodevelopmental disorder (NDD) that is classified as an autism spectrum disorder (ASD) in the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV)1 and occurs in approximately 1 in 10 000 female births.

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.

What treatments are used for 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.

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.

Is there hope for Rett syndrome?

Although there is no current effective treatment for Rett syndrome, previous work from the Zoghbi lab has shown that deep brain stimulation (DBS) can correct in animal models some of the symptoms, such as deficits in learning and memory.

Are there specific genes associated with classical EDS?

More than 90% of those with cEDS have a heterozygous mutation in one of the genes encoding type V collagen (COL5A1 and COL5A2). Rarely, specific mutations in the genes encoding type I collagen can be associated with the characteristics of cEDS. Classical EDS is inherited in the autosomal dominant pattern.

What are the symptoms of classic Rett syndrome?

Classic Rett syndrome, a progressive neurodevelopmental disorder primarily affecting girls, is characterized by apparently normal psychomotor development during the first six to 18 months of life, followed by a short period of developmental stagnation, then rapid regression in language and motor skills, followed by long-term stability.

How is MeCP2 related to classic Rett syndrome?

The diagnosis of all MECP2 -related disorders relies on molecular genetic testing. The diagnosis of classic Rett syndrome rests on clinical diagnostic criteria. Management. Treatment of manifestations: Treatment is mainly symptomatic and multidisciplinary and should include psychosocial support for family members.

How are mutations in collagen linked to classical EDS?

Collagen is a protein that provides structure and strength to connective tissues throughout the body. Mutations in COL5A1 or COL5A2 lead to defects in the structure and function of type V collagen molecules. This causes the many signs and symptoms associated with classical EDS.
