Integrative synaptosome multi-omics reveals disrupted synapse organization and localized cryptic transcripts in C9ORF72-frontotemporal dementia
Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) are linked neurodegenerative diseases characterized by both synaptic dysfunction and TDP-43 pathology. A hexanucleotide repeat expansion (HRE) in the C9ORF72 (C9) gene represents the most common genetic cause of FTD and ALS, yet the synapse-specific...
