 But proprietary understandings of privacy continue to find expression in health care and health research contexts. Scholars suggest that individuals have privacy interests in their genes, genomes and bio-banked tissue specimens. These are sources of health information that reflect what individuals and their biological families are like, and what will become of them. Since most people share a DNA profile with no one other than an identical twin, a person’s DNA is virtually a unique personal identifier. The interest individuals have in controlling the use of their data and specimens can be reconciled with researchers’ needs for genotypical and phenotypical data, where principles of informed consent are honored (Presidential Commission 2012). Many people are now willing to voluntarily share genetic data without personal gain. The United States National Institutes of Health “All of Us” project sought to enroll one million American volunteers of diverse backgrounds into a research program requiring that they share medical and genetic data to help accelerate the search for disease cures and treatments.
