Tauopathies, characterized by the presence of abnormally phosphorylated tau aggregates, are implicated in more than 20 types of age‐related neurodegenerative diseases, including frontotemporal dementia (FTDP‐17), Alzheimer's disease (AD), progressive supranuclear palsy (PSP), and so on [1]. Here, MAPT is linked to Alzheimer disease.
