June 24, 2011 -- Researchers have identified two new genetic variants linked to Parkinson's disease and say they now know how big a role heredity plays in the neurodegenerative disorder.he exact causes of Parkinson's disease are not known, but researchers now believe that both environmental triggers and genetic influences play a role. Genetic variants have been implicated in the small percentage of cases that occur in people under the age of 50, known as early-onset Parkinson's.
