Parkinson's Disease Genetic Influence
Recent developments in research gene research has found that genetic influence plays a large role in Parkinson's disease. Five main genes that are believed to contribute to the disease have been identified and located. These include alpha-synuclein, Parkin, Ubiquitin carboxyl-terminal hydrolase, DJ-1 and SCA2. It has been found that mutations of these genes are some of the underlying causes. In some causes there can be multiple mutations in one gene. The effects of some of these mutations are now understood.
Researchers suspect that genes associated with the late onset of Parkinson's Disease are susceptibility genes rather than causal genes. It is thought that environmental factors act on these gene, consequently leading to Parkinson's disease. But the mechanism in which they do so is not yet known. Researchers believe that if they can work out this mechanism, they can disrupt it in some way, and therefore halt the onset of the disease.
The general consensus among researchers is that both genetic influence and environmental factors lead to the onset of Parkinson's Disease. The mechanisms of the genetic influence of Parkinson's Disease are still to be understood and much more research is required.
