Mutations in Glucocerebosidase Gene Linked to Parkinson's Disease

"Mutations in the glucocerebosidase gene (GBA) appear to increase the risk of idiopathic Parkinson's disease, according to findings of study involving Ashkenazi Jews. Previous reports have shown type 1 Gaucher's disease, which is caused by certain GBA mutations, is associated with parkinsonism. However, the role of GBA mutations in idiopathic Parkinson's disease was unclear."
