The stored gap context says: Genetic aging landscape analysis identified PD-specific aging signatures but single-cell resolution of epigenetic aging in neuronal subtypes was not resolved.\n\nPrimary hypothesis: PD genetic aging variants accelerating cell-type-specific epigenetic clock trajectories is not merely an associated signature; it is a testable mechanism that can explain the open question: Do PD-associated genetic aging landscape variants causally accelerate epigenetic clock rates in specific neuronal subtypes (dopaminergic vs GABAergic vs cholinergic), and can single-nucleus multi-omic profiling of post-mortem PD brain resolve cell-type-specific epigenetic age acceleration?\n\nThree candidate claims should be carried forward. First, the strongest causal signal should appear in the cell type or tissue compartment named by the question, not only in bulk disease contrasts. Second, perturbing the axis should shift a proximal molecular phenotype before it shifts a late pathology phenotype, which would help separate cause from consequence. Third, the relevant readout should be stratified by PD-, because collapsing across those terms would erase the mechanism the analysis is trying to test.\n\nThe priority experiment is single-nucleus multi-omic clock estimation across dopaminergic, GABAergic, and cholinergic neurons with genotype-aware models. A positive result would require concordance across human observational data, disease-relevant cellular models, and at least one perturbation that moves the predicted proximal readout in the expected direction.",
