Insights
Neuronal ceroid lipofuscinoses (NCL), or Batten disease, are inherited neurodegenerative disorders in children. Research details genetic mutations and their impact on disease progression, aiding in understanding these rare conditions.
Area of Science:
- Genetics
- Neuroscience
- Pediatrics
Background:
- Neuronal ceroid lipofuscinoses (NCL), also known as Batten disease, are severe inherited neurodegenerative disorders.
- These conditions primarily affect children, leading to visual failure, seizures, and progressive decline.
Purpose of the Study:
- To summarize the genetic basis of human NCL.
- To document identified mutations and their correlation with disease phenotypes.
Main Methods:
- Review of identified genes causing human NCL (CLN1-CLN3, CLN5, CLN6, CLN8).
- Cataloging of approximately 150 described mutations.
- Analysis of mutation distribution and disease course variations.
Main Results:
- Six genes are identified as causative for human NCL.
- Around 150 mutations have been described, with most mutations correlating to specific disease courses.
- Seven common mutations show either global or country-specific prevalence.
Conclusions:
- Genetic mutations in specific CLN genes dictate the NCL disease course.
- The NCL Mutation Database serves as a comprehensive resource for all described mutations.
Abstract:
The neuronal ceroid lipofuscinoses (NCL), also known as Batten disease, are a group of inherited severe neurodegenerative disorders primarily affecting children. They are characterised by the accumulation of autofluorescent storage material in many cells. Children suffer from visual failure, seizures, progressive physical and mental decline and premature death, associated with the loss of cortical neurones. Six genes have been identified that cause human NCL (CLN1, CLN2, CLN3, CLN5, CLN6, CLN8), and approximately 150 mutations have been described. The majority of mutations result in a characteristic disease course for each gene. However, mutations associated with later disease onset or a more protracted disease course have also been described. At least seven common mutations exist, either with a world-wide distribution or associated with families from specific countries. All mutations are described in the NCL Mutation Database (http://www.uc.ac.uk/ncl).
