Glucocerebrosidase is present in α-synuclein inclusions in Lewy body disorders.

ABSTRACT: Mutations in the gene encoding the lysosomal enzyme glucocerebrosidase, known to cause Gaucher disease (GD), are a risk factor for the development of Parkinson disease (PD) and related disorders. This association is based on the concurrence of parkinsonism and GD, the identification of glucocerebrosidase mutations in cohorts with PD from centers around the world, and neuropathologic findings. The contribution of glucocerebrosidase to the development of parkinsonian pathology was explored by studying seven brain samples from subjects carrying glucocerebrosidase mutations with pathologic diagnoses of PD and/or Lewy body dementia. Three individuals had GD and four were heterozygous for glucocerebrosidase mutations. All cases had no known family history of PD and the mean age of disease onset
