Parkinson's genomic pathway discovered ROCHESTER, Minn., June 18 (UPI) -- U.S. scientists have discovered a "genomic pathway" that can be used to predict the risk of developing Parkinson's disease, as well as the age of onset. The Mayo Clinic study suggests the joint effects of common DNA variations in several genes that encode proteins within a biological pathway largely explain why some people develop Parkinson's disease while others do not -- and can be used to even predict, with great accuracy, at what age a person might develop their first symptoms. "This represents a major paradigm shift from single gene studies to genomic pathway studies of complex diseases," said Dr. Demetrius Maraganore, a Mayo Clinic neurologist and Parkinson's disease specialist who led the study. The findings are published in the June 15 issue of PLoS Genetics. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
