In particular, oligodendroglial TDP43 inclusions were specifically associated with mutations in several genes linked to ALS (e.g., angiogenin, C9orf72 and optineurin) or FTD (e.g., C9orf72, progranulin and sequestosome 1) (Seilhean et al., 2009; Kovacs et al., 2016). Here, TARDBP is linked to frontotemporal dementia.
