Introduction

Gaucher disease is a rare genetic disorder that results in the abnormal build-up ofmaterialinside the cells of the body. There are three forms—Types I, II, and III. Type I is themost common and least severe form of Gaucher disease. The symptoms of Type IGaucherdisease vary greatly—some people are entirely asymptomatic, while others mayhaveproblems with their liver, spleen, bones and/or blood count that need to be treated.TypesII and III are both more severe and affect thebrain.

Carriers of Gaucher disease are not affected by the disease, but they are at risk of havinga childwiththediseaseiftheirpartnerisalsoacarrier. AnyonecanbeacarrierofGaucherdisease, but people of Eastern European Jewish descent are more likely to becarriers.

Parkinson’s disease is a neurodegenerative disease. It causes tremor, slowness andotherneurologic symptoms. There is no cure for Parkinson’s disease, and it cannot beprevented.

The risk for developing Parkinson’s disease is about 2% in the elderly population.Recent studies have shown that carriers for Gaucher disease have about a 10% risk ofdeveloping Parkinson’sdisease.
