The distribution of TDP-43 pathology in the case by Kouri et al. (2013) was more unusual, differing from other previously reported cases of co-pathology in CBD, and was associated with both TDP-43 and tau pathology in the olivopontocerebellar system, suggesting a role in phenotypic presentation (Kouri et al., 2013). Here, MAPT is linked to red-green color blindness.
