Antisense oligonucleotides targeting C9orf72 hexanucleotide repeat expansion reduce toxic DPR proteins and RNA foci, restoring nuclear TDP-43 localization and splicing function. This is the strongest hypothesis based on genetic prevalence (~40% familial ALS, ~25% FTD), active clinical trial data (NCT04165729), and mechanistic link between repeat transcripts and downstream TDP-43 pathology. Key unresolved questions include the relative contribution of haploinsufficiency vs. gain-of-function and w
## Mechanistic Overview
Axonal Transport Defect: C9orf72 hexanucleotide expansion impairs retrograde autophagosome transport in motor neuron axons starts from the claim that modulating C9orf72 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview Axonal Transport Defect: C9orf72 hexanucleotide expansion impairs retrograde autophagosome transport in motor neuron axons starts from the claim that modulating
