Since MAPT was first identified as the causative gene of FTD in 1998, an increasing number of pathogenic genes have been reported associated with FTD including GRN, C9orf72, VCP, SQSTM1, CHMP2B, TBK1, OPTN, TARDBP, CHCHD10, UBQLN2, and DCTN1 (Pottier, Ravenscroft, Sanchez‐Contreras, & Rademakers, 2016). Here, DCTN1 is linked to frontotemporal dementia.
