Gene-corrected p.A30P SNCA patient-derived isogenic neurons rescue neuronal branching and function

Abstract Parkinson’s disease (PD) is characterised by the degeneration of A9 dopaminergic neurons and the pathological accumulation of alpha-synuclein. The p.A30P SNCA mutation generates the pathogenic form of the alpha-synuclein protein causing an autosomal-dominant form of PD. There are limited st...
