Challenge: Efficiently Reach
Large N for Population studies
• High throughput genotyping
• High throughput phenotyping
• High throughput sample acquisition
DHHS Secretary’s Advisory Committee on
Genetics, Health, and Society (SACGHS)
argues for the health value of a 500,000 to 1M
subject study. Estimated cost: $3,000,000,000
