Thus, Lewy bodies and α-synuclein in PD, β-amyloid peptides, and phosphorylated tau/tau proteins are common in AD (Duong and Gallagher, 1994; Elobeid et al., 2016), superoxide dismutase in ALS (Durham et al., 1997) and mutant huntingtin in HD (Scherzinger et al., 1997). This evidence concerns the gene MAPT and amyotrophic lateral sclerosis.
