Geneticists believe they will need DNA samples from hundreds of thousands of people before they have amassed enough data to make possible the identification and treatment of certain diseases resulting from interactions between genes and the environment.
To collect, analyze, and store such vast quantities of DNA, gene banks are being created around the world. Two such ventures were initiated this fall at Northwestern University in Chicago and the Marshfield Clinic in Marshfield, Wis. Investigators at each center want to enroll at least 100 000 people within a decade, study and store their DNA, and make data available to other researchers.
