Summary
This study reports on a pair of identical twins with typical Parkinson's disease (PD), suggesting a genetic link. Their similar symptom onset and progression highlight the importance of genetic susceptibility in PD development.
Area of Science:
- Neuroscience
- Genetics
- Epidemiology
Background:
- Parkinson's disease (PD) concordance in identical twins is lower than expected.
- Previously reported concordant identical twin pairs with PD had atypical disease characteristics.
