**Molecular Mechanism and Rationale**
The fundamental molecular mechanism underlying this hypothesis centers on the aberrant liquid-liquid phase separation (LLPS) properties of mutant FUS proteins and their consequent resistance to autophagic clearance. FUS (Fused in Sarcoma) is an RNA-binding protein containing a low-complexity domain (LCD) that drives LLPS under cellular stress conditions. Wild-type FUS undergoes reversible phase separation to form membraneless organelles called stress granul
## **Molecular Mechanism and Rationale**
The hexanucleotide repeat expansion (GGGGCC) in the C9orf72 gene represents the most prevalent genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), accounting for approximately 40% of familial ALS cases and 25% of familial FTD cases. This expansion undergoes repeat-associated non-ATG (RAN) translation, generating five distinct dipeptide repeat proteins (DPRs): poly-glycine-proline (poly-GP), poly-glycine-arginine (poly-
