The Icelandic biotech firm deCODE Genetics has pioneered a means of determining an individual’s susceptibility to various medical conditions with 99 percent accuracy by gathering information about that person’s relatives, including their medical and genealogical records. Of course, inferences have long been made about a person’s health by observing and gathering information about her relatives. What is unique about deCODE’s approach in Iceland is that the company uses the detailed genealogical records available in that country in order to estimate genotypes of close relatives of individuals who volunteered to participate in research, and extrapolates this information in order to make inferences about hundreds of thousands of living and deceased Icelanders who have not consented to participate in deCODE’s studies. DeCODE’s technique is particularly effective in Iceland, a small island nation that, due to its largely consanguineous population and detailed genealogical records, lends itself particularly well to genetic research.

While Iceland’s detailed genealogical records enable the widespread use of estimated data in Iceland, a large enough U.S. database could be used to make similar inferences about individuals here. While the U.S. lacks a national database similar to Iceland’s, private companies such as 23andme and Ancestry.com have created rough gene maps of several million people, and the National Institutes of Health plans to spend millions of dollars in the coming years sequencing full genome data on tens of thousands of people. These databases could allow the development of estimated data on countless U.S. citizens.
