Search For Parkinson’s Genes Turns To Online Social Networking

There’s a growing interest in what our genes say about our health. And in recent years, quite a few companies have sprung up to help us listen with the help of personalized DNA tests.

For a few hundred dollars and a vial of spit, these companies will search your DNA for sequences that predict your physical traits, your response to certain drugs and your risk for any number of diseases.

One such company, California-based 23andMe, is attempting to use the data to do something different: search for new genes linked to Parkinson’s disease. The company, which calls itself the world’s first genetics-based social network, has collected more than 125,000 DNA samples from customers.
