So that immediately cuts down the problem to something like 500,000 gene-associated variations that are either in genes or very near them. But that's still a big number, and to study 500,000 variations in a typical 2,000-person control study would mean that you make a billion measurements during a clinical trial, which is not possible. You have to do something to compress the problem further, and the major thing we've learned is that we can pool DNA from different people and study pools that are representative of the population.
