The project will publish the genotype (the full DNA sequence of all 46 chromosomes) of the volunteers, along with extensive information about their phenotype: medical records, various measurements, MRI images, etc. All data will be freely available over the Internet, so that researchers can test various hypotheses about the relationship between genotype and phenotype.
The published data will include identifyable information such as the volunteers’ name. The reason for doing so is that they can’t guarantee anonymity anyways when one’s genotype and phenotype are already open. In an interview in Technology Review, the project’s founder, Harvard University’s George Church, said:
We and others have raised concerns about the difficulty of maintaining anonymity [in medical records]. You promise subjects you will make the information anonymous, but it’s becoming increasingly easy to re-identify an individual. This project will hopefully raise consciousness on what we need to do to encourage insurance companies and government and employers to make this safer. This has already been done in some countries, so it’s just a matter of policy.
The first volunteers will be tenured human geneticists, who best understand the risk and benefits of this project. Harvard Medical School’s Institutioal Review Board had given the project permission to start, and it sounds like they will review its progress before the project will recruit a broader set of volunteers.
