## Mechanistic Overview
Neuronal Subtype-Specific Alpha-Synuclein Expression Normalization starts from the claim that modulating SNCA within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Background and Rationale** Parkinson's disease (PD) and other synucleinopathies are characterized by the accumulation of misfolded alpha-synuclein (α-syn) protein, encoded by the SNCA gene, in specific neuronal populations.
