Cloning of a gene mutation for parkinson's disease

Abstract

Parkinson's disease (PD) is a common neurodegenrative disorder with a lifetime incidence of approximately 2 percent. It was recently reported that a PD susceptibility gene is located on the long arm of human chromosome four. The present invention reports the subsequent identification of a mutation in the alpha synuclein gene, which codes for a presynaptic protein thought to be involved in neuronal plasticity. The finding of a specific molecular alteration which is causative for PD will permit the detailed understanding of the pathophysiology of the disorder, which will lead to potential therapetuic interventions, as well as a means for diagnosing individuals having an increased risk of developing the disease.
