MAPT and amyotrophic lateral sclerosis: Neuropathological analyses of lesions corresponding to the brain regions used for microarray analysis showed that the accumulation of disease-specific abnormal proteins (phosphorylated tau, p = 0.0355; phosphorylated α-synuclein, p = 0.0186; and phosphorylated TDP-43, p = 0.6624) in Kii PDC brains tended to be more severe than in Kii ALS brains (Supplementary Figure S3).
