For instance, some TDP-43 PTMs are specific to FTLD-TDP type A (associated with GRN mutations) and some are specific to type B (associated with C9orf72 mutations) [55], phosphorylated Tyr526 FUS is present in the FTLD-FUS pathology [54,56], and the acetylation of K280/K281 in tau increases aggregation in AD. The gene discussed is FUS; the disease is Alzheimer disease.
