Hypothesis

C9orf72 Nucleocytoplasmic Transport Rescue for ALS/FTD

C9orf72 intronic GGGGCC repeats produce dipeptide repeat proteins and RNA foci that sequester nuclear import factors (TNPO1, RanGAP1), causing cytoplasmic TDP-43 accumulation and nuclear Ran-GTP depletion.

🧪 Overview

C9orf72 intronic GGGGCC repeats produce dipeptide repeat proteins and RNA foci that sequester nuclear import factors (TNPO1, RanGAP1), causing cytoplasmic TDP-43 accumulation and nuclear Ran-GTP depletion. Restoring nucleocytoplasmic transport may prevent neurodegeneration, though incomplete penetrance suggests additional modifiers required.

⚖️ Evidence

⚖️ Evidence Matrix4 supports4 contradicts
Supports
C9orf72 expansions cause ALS/FTD with TDP-43 pathology
Supports
DPR proteins localize to nuclear pores and disrupt nuclear import
Supports
RanGAP1 mislocalization demonstrated in C9-BAC transgenic mice
Supports
C9-BAC mice develop motor deficits and TDP-43 pathology
Contradicts
~50% of C9orf72 expansion carriers remain asymptomatic by age 80 (incomplete penetrance)
Contradicts
C9orf72 knockout mice develop splenomegaly and immune dysfunction, not neurodegeneration
Contradicts
RanGAP1 mislocalization occurs in sporadic ALS without C9orf72 mutation
Contradicts
TDP-43 pathology is common endpoint of ALS/FTD regardless of genetic cause
