Association between plasma glucosylsphingosine levels and dyskinesia burden in GBA1-related Parkinson's disease

Background: GBA1 mutation is the most significant genetic risk factor for Parkinson's disease (PD). It encodes glucocerebrosidase (GCase), whose dysfunction – seen in Gaucher disease - leads to the accumulation of glucosylceramide and its derivate glucosylsphingosine (GlcSph). However, it remains un...
