C9ORF72 repeat expansions in mice cause TDP-43 pathology, neuronal loss, and behavioral deficits

Abstract excerpt

The major genetic cause of frontotemporal dementia and amyotrophic lateral sclerosis is a G4C2 repeat expansion in C9ORF72. Efforts to combat neurodegeneration associated with "c9FTD/ALS" are hindered by a lack of animal models recapitulating disease features. We developed a mouse model to mimic both neuropathological and clinical c9FTD/ALS phenotypes. We expressed (G4C2)66 throughout the murine central nervous...
