Hypothesis
early PD proteogenomic hubs that are both causal enough and accessible enough to perturb as proximal driver in Proteogenomic Network Hubs as Druggable Targets in Early PD Neurodegeneration
early PD proteogenomic hubs that are both causal enough and accessible enough to perturb should produce a measurable proximal phenotype before late disease pathology.

🧪 Overview
early PD proteogenomic hubs that are both causal enough and accessible enough to perturb should produce a measurable proximal phenotype before late disease pathology. The decisive test is multi-omics network centrality, druggability scoring, interactome validation, and SNCA iPSC-neuron perturbation assays.

IF we CRISPR-perturb top-ranked proteogenomic hub genes (identified by multi-omics network centrality >2 SD above mean) in SNCA-A53T iPSC-derived dopaminergic neurons, THEN we will observe a significant decrease in synaptic vesicle release probability (measured by vGlut1/parkin colocalization and sp

Falsification: Non-hub gene perturbations produce equivalent or greater synaptic dysfunction than hub perturbations, indicating network centrality does not predict proximal phenotype.
