Clinical Genetics
Neurogenetics
Genetic contributions to neurological and neurodevelopmental conditions.
Scientific context
Understanding the field
Studies span monogenic epilepsies, neurodegenerative disorders, repeat expansion diseases and the genetics of neurodevelopment.
Neurogenetics investigates genetic contributions to neurological and neurodevelopmental conditions, from highly penetrant variants to complex susceptibility. Phenotype, age of onset and family structure guide analysis.
Central questions
- Which molecular mechanisms explain a neurological phenotype?
- How do repeat, mosaic and mitochondrial variants contribute?
Methodological framework
- Genome, repeat-expansion and mitochondrial analysis
- Deep phenotyping and family segregation
- Functional and transcript-level follow-up
Relevance
Scientific and clinical value
A well-supported molecular explanation may inform prognosis, surveillance, family counselling and eligibility for condition-specific research, without implying a guaranteed treatment.
Limits and responsibility
Variable expressivity, age-dependent penetrance and uncertain findings complicate prediction. Testing can reveal sensitive family information and requires consent appropriate to adults, children and future risk.
