🔮 Falsifiable Predictions (2)
pendingconf 55%
IF ATAC-seq accessibility distinguishes pathological age-related methylation drift, THEN drift loci that predict degeneration will have >=1.4-fold accessibility gain in vulnerable neuronal nuclei before cell-loss signatures emerge.
Predicted outcome: Pathological drift loci show >=1.4-fold ATAC accessibility increase before cell-loss gene signatures.
Falsification: Accessibility fold-change is <1.1 or follows rather than precedes cell-loss signatures.
pendingconf 48%
IF compensatory methylation states are accessibility-silent, THEN protective drift loci will show <10% ATAC change while still associating with slower NfL rise over 24 months.
Predicted outcome: Protective drift loci have <10% accessibility change and predict >=15% slower NfL slope.
Falsification: Protective loci show the same accessibility shifts as pathological loci or do not predict NfL slope.
