Mutations in the Glucocerebrosidase Gene and Parkinson's Disease in Ashkenazi Jews

Abstract

A clinical association has been reported between type 1 Gaucher's disease, which is caused by a glucocerebrosidase deficiency owing to mutations in the glucocerebrosidase gene (GBA), and parkinsonism. We examined whether mutations in the GBA gene are relevant to idiopathic Parkinson's disease.
