Human Genetic Variation:
2007 Breakthrough of the Year

On 21 December 2007, Science unveiled its Breakthrough of the Year for 2007 -- the realization that DNA differs from person to person much more than researchers had suspected. That conceptual advance, driven by results from several fields, may transform medicine, but could also threaten personal privacy.

In this video presentation, featuring Science news writer Liz Pennisi, Francis Collins of the National Institutes of Health, and David Altshuler of the Harvard/MIT Broad Institute, we offer a look at the past year's discoveries in human genetic variation and their implications.
