Finally, transcripts known to be involved in Tau- and synucleinopathies include IGLON5, CAV1, GFRA2, SYNGR3, and SLC6A3, with the latter being particularly interesting as its genetic variants lead to Parkinsonism-dystonia infantile (PKDYS) syndrome [49]. The gene discussed is SLC6A3; the disease is synucleinopathy.
