Parkinson's disease (PD) is a common neurodegenerative disorder affecting greater than two percent of individuals over the age of 65. The disease is characterised by tremor, slowness of movement, rigidity and postural instability. Current treatment regimes may provide some measure of symptomatic relief, but currently there is no treatment to halt or slow the progression of this debilitating disease. PD currently affects an estimated 35,000 people in Australia and this figure is predicted to increase significantly as the population ages. PD is a complex disorder, the causes and disease mechanisms are not well understood. However, in the past 10 years several genes have been identified that can cause PD when disrupted. We have identified a new gene that we believe may be involved in PD. The overall aim of this proposal is to characterise this gene and what role it plays in the development of PD. Understanding the expression and function of this gene may significantly advance our understanding of this disorder. Using these results, we aim to model Parkinson's disease in cellular and animal systems; these may provide powerful insight into the molecular pathway(s) perturbed in PD and a means to develop novel therapeutic approaches to alleviate or prevent the disorder.
