Hypothesis
age-linked CpG drift is the actionable driver in: Are age-related DNA methylation changes protective adaptations or pathological drivers in
The gap can be tested by treating age-linked CpG drift as an upstream driver rather than a passive correlate.

🧪 Overview
The gap can be tested by treating age-linked CpG drift as an upstream driver rather than a passive correlate. If true, perturbing locus-specific epigenome editing should shift cell-sorted methylomes before downstream neurodegeneration markers change.
