Homozygous glucocerebrosidase mutations cause Gaucher disease, whereas heterozygous mutations are the most important genetic risk factor for Parkinson's disease (PD). The penetrance of heterozygous glucocerebrosidase mutations for PD is variable (10%–30%), depends on the population studied, and has only been assessed in Gaucher disease or familial PD. The aim of this study was to assess the penetrance of glucocerebrosidase mutations in PD in unselected PD patients.
