Examination of the post-mortem brain studies presented in Table 2 indicates that although PARK2-mediated PD is not thought to be associated with Lewy body pathology, 8 of 17 cases (corresponding to 47%) reported classical Lewy body pathology [131,132,133,134,135,136,137] despite one of the cases reporting Lewy body-like inclusions [138]. Here, PRKN is linked to Parkinson disease.
