TDP-43 has been reported as a co-pathology in other neurodegenerative disorders besides AD, including Huntington’s disease, progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), argyrophilic grain disease, DLB, and multiple system atrophy (MSA) [10, 120, 126, 128, 164–170]. Here, TARDBP is linked to multiple system atrophy.
