These symptoms are commonly associated with neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), Creutzfeldt–Jakob disease, Huntington's disease, and amyotrophic lateral sclerosis [2], all of which are characterized by extensive deposits of misfolded protein aggregates, including β‐amyloid peptide (Aβ), hyperphosphorylated tau, α‐synuclein, Huntington protein, and TAR DNA‐binding protein 43 [3, 4]. The gene discussed is MAPT; the disease is Parkinson disease.
