Researchers Identify Gene Mutations Underlying Risk for Most Common Form of Parkinson's Disease – 1
Narrator: This is NIH Health Matters. Researchers have found that two genes containing mutations known to cause rare familial forms of Parkinsonís disease are also associated with the more common form of the disease where there is no family history.
Dr. Singleton: Theyíre present in 20 or 30 percent of the population.
Narrator: Dr. Andrew Singleton is with the National Institute on Aging
Dr. Singleton: These common variants increase our risk.
Narrator: Dr. Singleton emphasizes that these genetic mutations donít cause Parkinsonís disease. The likelihood of developing the disorder increases with age and involves a combination of environmental risk factors and genetic susceptibility.
