Rett Syndrome

Disease Overview

Rett syndrome is a rare genetic neurological and developmental disorder that primarily affects females, characterized by severe cognitive and physical disabilities that emerge after an initial period of normal early development. The disorder results in progressive neurological impairment and significant developmental challenges.

Disease Category

Rare genetic neurological and developmental disorder

Synonyms

RTT
Autism-dementia-ataxia-loss of purposeful hand use syndrome
MECP2-related neurodevelopmental disorder

Signs & Symptoms

Progressive loss of purposeful hand skills
Stereotypic hand movements (hand-wringing, washing, clapping)
Severe speech and language impairment
Cognitive disabilities
Seizures and epilepsy
Slowed physical growth and development
Abnormal gait and motor skills
Breathing irregularities (hyperventilation, breath holding)
Scoliosis
Sleep disturbances
Reduced social interaction

Causes

Primarily caused by mutations in the MECP2 gene (located on X chromosome)
Most cases are spontaneous mutations
Extremely rare inherited cases
Affects protein production critical for neural development and function
Almost exclusively affects females due to X-chromosome linked inheritance

Affected Populations

Prevalence: 1 in 10,000 to 15,000 female births
Predominantly affects females
Males with mutations typically experience more severe symptoms and often do not survive infancy
Occurs across all racial and ethnic groups

Disorders with Similar Symptoms

Autism spectrum disorder
Angelman syndrome
Cerebral palsy
Childhood disintegrative disorder
Fragile X syndrome

Diagnosis

Clinical evaluation of developmental history and symptoms
Genetic testing for MECP2 gene mutations
Neurological examination
Developmental assessments
Ruling out other similar neurological disorders
Brain imaging studies
Electroencephalogram (EEG) to assess seizure activity

Standard Therapies

Multidisciplinary supportive care
Physical therapy
Occupational therapy
Speech and communication therapy
Seizure management with anticonvulsant medications
Nutritional support
Assistive communication technologies
Orthopedic interventions for scoliosis
Behavioral and psychological support

Clinical Trials and Studies

Ongoing research into:
- Gene therapy
- Neurological rehabilitation techniques
- Pharmacological interventions
- Stem cell therapies
- Symptom management strategies
