In CBD, although BRCA1 colocalization with tau aggregates was not observed in the precentral gyrus and midbrain in all of the three patients in our study, Nakamura et al. reported BRCA1 colocalization with astrocytic plaques and intracytoplasmic inclusions in the basal ganglia (caudate and putamen) in all of the five patients in their study [11]. The gene discussed is MAPT; the disease is red-green color blindness.
