XXIV. SCF LAYMAN’S SUMMARY
Dentatorubral-pallidoluysian atrophy (DRPLA) is a rare inherited neurodegenerative disorder caused by an abnormal expansion of CAG repeats in the ATN1 gene. The mutation produces a toxic protein that accumulates inside neurons, gradually damaging regions of the brain responsible for movement, cognition, behavior, and seizure control. Patients may develop ataxia, chorea, epilepsy, dementia, psychiatric symptoms, and progressive neurologic disability. SCF interprets DRPLA as a systems-level neurocommunication disorder involving toxic protein aggregation, mitochondrial dysfunction, oxidative injury, neuroinflammation, and collapse of synchronized cerebellar–basal ganglia regulatory systems.
