CEs in the transcripts of STMN2 and KALRN were detected in multiple neuronal subtypes, as well as non-neuronal cell types, in all C9ORF72 disease groups in a manner reflective of the expected level of TDP-43 pathological burden in the frontal cortex for each group (C9-FTD > C9-ALS/FTD > C9-ALS). The gene discussed is TARDBP; the disease is frontotemporal dementia.
