When considering combined dystonia forms, particularly promising outcomes can be expected in XDP patients (Brüggemann et al. 2019; Abejero et al. 2019) and myoclonus dystonia patients with SGCE variants (Kosutzka et al. 2019), but not for ATP1A3-related dystonia (DYT/PARK-ATP1A3) (Brücke et al. 2015; Albanese et al. 2017; Tisch and Kumar 2021). Here, ATP1A3 is linked to Dystonia.
