PRKN and synucleinopathy: The presence or absence of synucleinopathy can also be examined in colon, submandibular gland or skin (Del Tredici, Hawkes, Ghebremedhin, & Braak, 2010; Ikemura et al., 2008; Wakabayashi, Takahashi, Ohama, & Ikuta, 1990), and it will be interesting to investigate PARKIN PD at these sites for α‐synuclein pathology.
