Sergey Brin’s Search for a Parkinson’s Cure

Why not do science differently? Gather tons of data, then start searching for correlations.

... “Traditionally, an experiment with 10 or 20 subjects was big,” says the Parkinson’s Institute’s Langston. “Then it went up to the hundreds. Now 1,000 subjects would be a lot—so with 10,000, suddenly we’ve reached a scale never seen before. This could dramatically advance our understanding.”

Langston offers a case in point. Last October, the New England Journal of Medicine published the results of a massive worldwide study that explored a possible association between people with Gaucher’s disease—a genetic condition where too much fatty substances build up in the internal organs—and a risk for Parkinson’s. The study, run under the auspices of the National Institutes of Health, hewed to the highest standards and involved considerable resources and time. After years of work, it concluded that people with Parkinson’s were five times more likely to carry a Gaucher mutation.

Langston decided to see whether the 23andMe Research Initiative might be able to shed some insight on the correlation, so he rang up 23andMe’s Eriksson, and asked him to run a search. In a few minutes, Eriksson was able to identify 350 people who had the mutation responsible for Gaucher’s. A few clicks more and he was able to calculate that they were five times more likely to have Parkinson’s disease...
