PARK7 and dystonic disorder: That study showed that five genes were included in all panels (SNCA, PRKN, PINK1, PARK7 (DJ1), and LRRK2), while VPS35 and GBA were only variably included, and that the differences between panels were mainly the result of the variable inclusion of genes associated with atypical parkinsonism and dystonia disorders, or genes with an uncertain association with PD [139].
