Diagnosing typical Rett syndrome A diagnosis of typical Rett syndrome requires five symptoms of decline: a period of regression returning to a less developed state during the first five years of life, followed by recovery or stabilisation partial or complete loss of purposeful hand skills learned hand movements such as grasping, holding or self-feeding partial or complete loss of language skills speech walking gait abnormalities, such as an unsteady walk or an inability to walk repetitive hand movements such as hand wringing or hand squeezing, clapping or tapping, mouthing and hand washing or hand rubbing movements.
Diagnosing atypical Rett syndrome A diagnosis of atypical Rett syndrome requires a period of regression returning to a less developed state during the first five years of life, followed by recovery or stabilisation, and at least two of the other four symptoms for a diagnosis of typical Rett syndrome.
Genetic testing for Rett syndrome A genetic test that reveals a change in the MECP2 gene is used to confirm a diagnosis that has already been determined or is already suspected by a medical professional. Stages of Rett syndrome Rett syndrome has four stages: stage 1 — early onset — between the ages of 6 and 18 months, development slows, developmental milestones may not be met stage 2 — rapid destructive regression phase — loss of acquired skills such as loss of purposeful hand skills and speech and walking skills.
This stage generally occurs between the age of one and four years. Other symptoms of Rett syndrome may occur stage 3 — plateau stage — abilities stabilise; intensity of symptoms may lessen.
This stage can last for years stage 4 — late motor deterioration loss of movement — begins between five and 25 years of age, can last for decades but may not occur in all individuals. Involves reduced movement, muscle weakness and joint stiffness. Treatment for Rett syndrome There is no cure for Rett syndrome, but therapy can help slow the progress of movement loss.
Therapies include: physiotherapy to prevent deformities of the joints and to improve movement occupational therapy to improve hand use horseback riding music therapy hydrotherapy exercise in water other environmental enrichment activities.
Drug trials for Rett syndrome Drug trials of Anavex commenced in Australia in and are continuing throughout , depending on the coronavirus COVID situation. Communication with a child with Rett syndrome Children with Rett syndrome have a keen desire to communicate. Methods for communication may include: touch pictures and letters word boards eye gaze, via the use of computer-related devices such as My Tobii and iPad switch-operated voice output devices.
Education for a child with Rett syndrome Most children with Rett syndrome attend specialist schools; some may attend a mixture of specialist and mainstream school, and some just mainstream. They need: early exposure to toys and music age- and developmentally-appropriate activities a school environment that provides strong motivation. Genetic counselling and Rett syndrome If your child has been diagnosed with Rett syndrome it may be helpful to speak to a genetic counsellor.
Support for people and families living with Rett syndrome The Genetic Support Network of Victoria GSNV is connected with a wide range of support groups throughout Victoria and Australia and can connect you with other individuals and families affected by 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. We bring together a team of physicians and therapists from various fields who have expertise in Rett syndrome. For Patients. Contact the Rett Syndrome Program Email rettresearch childrens.

Symptoms can include: significantly impaired communication and cognitive thinking abilities loss of the ability to speak autistic -like symptoms, such as social isolation or withdrawal and reduced eye contact compulsive hand movements, such as hand wringing, hand clasping, hand clapping, or repeatedly moving the hands toward the mouth loss of motor skills, such as walking or crawling breathing problems, including breath holding and hyperventilation seizures sleep problems gastrointestinal problems, such as reflux and constipation heart rhythm abnormalities, such as QT syndrome scoliosis kyphosis microcephaly small head size low muscle tone irritability or agitation teeth grinding bruxism difficulty chewing and swallowing dysphagia drooling What are the causes of Rett syndrome?
Frequently asked questions about Rett syndrome Why is Rett syndrome usually only found in girls? My child was fine. Why does Rett syndrome seem to suddenly appear out of nowhere? How common is Rett syndrome? If I have one child with Rett syndrome, do my chances of having another child with the condition increase? Can Rett syndrome be prevented? There is no known way to prevent Rett syndrome.
Only one X chromosome in a given cell remains active throughout life and cells randomly determine which X chromosome will remain active. If the cells have an active mutated gene more often than the normal gene, the symptoms of Rett syndrome will be more severe.
This random process allows most females with Rett syndrome to survive infancy. Because most boys have only one X chromosome, when this gene is mutated to cause Rett syndrome the detrimental effects are not softened by the presence of a second, normal X chromosome. As a result, many males with Rett syndrome are stillborn or do not live past infancy.
Duplication of the MECP2 gene can occur in boys and affects intellectual and physical function. Is Rett syndrome passed from one generation to the next? This means that some of the X chromosome genes in a boy's body have the Rett mutation, and some genes do not have the mutation.
When a lower percentage of genes have the Rett syndrome mutation, the symptoms are not as severe. A boy may have two X chromosomes and one Y chromosome Klinefelter syndrome. Only one X chromosome will be active in each cell, so if one X carries a mutation in MECP2 , the severity of symptoms will depend on how many cells have that the mutant X active in the body.
The genetic mutation is less severe than that of other forms of Rett syndrome mutations. Citations Close Citations Amir, R. Nature Genetics , Oct;23 2 , — Schollen, E. Human Mutations , 22, —
