1Neurogenetics Unit, Kennedy Krieger Institute, Baltimore, MD 21205, USA.
Insights
Rett syndrome (RS) is a rare neurological disorder primarily affecting girls, characterized by developmental regression and distinct clinical features. Further research into its pathogenesis could illuminate normal brain development.
Area of Science:
- Neurology
- Genetics
- Developmental Biology
Background:
- Rett syndrome (RS) is a significant neurological disorder predominantly affecting females.
- Current diagnosis relies on clinical features, lacking a definitive biological marker.
- RS is recognized as a distinct, genetically determined condition.
Purpose of the Study:
- To summarize the current understanding of Rett syndrome.
- To highlight the neuropathological and neurochemical aspects of RS.
- To emphasize the potential of RS research for understanding normal brain development.
Main Methods:
- Clinical observation and diagnosis based on established criteria.
- Review of neuropathological and neurochemical studies.
- Genetic analysis to understand the underlying cause.
Main Results:
- Rett syndrome presents with a consistent set of clinical features globally.
- A biological marker for RS has not yet been identified.
- The disorder involves a loss of function in early childhood, followed by a static phase.
Conclusions:
- Rett syndrome is a distinct neurodevelopmental disorder of infancy characterized by impaired brain growth.
- Understanding RS pathogenesis offers insights into typical brain development processes.
- Further investigation is crucial for identifying biomarkers and improving diagnostic accuracy.
Abstract:
Rett syndrome (RS) is a neurological disorder that mainly, and possibly exclusively, affects girls. Diagnosis continues to be based upon a consistent constellation of clinical features observed in all of the patients worldwide. A biological marker has not been identified. In spite of this serious limitation, it is generally agreed that RS is a distinct entity and that it is genetically determined. Although it is associated with loss of function between infancy and the fifth year of life, its course becomes relatively static thereafter, setting it apart from most of the genetic neurodegenerative disorders of childhood. Neuropathological and neurochemical studies call attention to RS as a neurodevelopmental disorder of infancy resulting in failed brain growth. Clarification of its pathogenesis may provide new insight into normal brain development.
