FUS and TPD-43 (TARDBP), marker and risk proteins linked to FTD that accumulate in the frontal and temporal lobes, were evaluated, as well as risk proteins that overlap between FTD and ALS including SQSTM1, VCP, TBK1, CHCHD10, C9orf72, and progranulin (GRN) [23,24]. The gene discussed is C9orf72; the disease is frontotemporal dementia.
