Who Should Get The Benefits When You Donate Your DNA For Research?

Because of that unique ability to store key data about people, collections of DNA have become a hugely important scientific resource. And because DNA is so intimately bound up with a single, identifiable individual, they naturally feel a very strong connection to that digital string and how it is used. Both of those traits are evident in this fascinating story from the Guardian about Sardinia's "Blue Zone" with its unexpectedly long-lived inhabitants:
The story starts nearly 20 years ago when Gianni Pes, a Sardinian scientist at Sassari University, visited nearly all of Sardinia’s 377 municipalities to try to prove that certain areas had an unusually large number of people who lived extremely long lives. When they found a town that met their criteria, they marked it on their map with a blue marker. When they were done, the Sardinian Blue Zone was established.
Naturally, scientists are keen to understand whether there is some genetic characteristic shared by these exceptional individuals:
In all, four databases of DNA samples have been collected over the years, with some researchers refusing to collaborate with others.
That hints at the deepening bitterness that has engulfed this area of research, as two groups claim the right to investigate one of the region's DNA databases:
One of them was Shardna, created by a scientist called Mario Pirastu. Another entity, a partly publicly funded group called Parco Genetico, was established at the same time to facilitate the data collection and act as an intermediary between Shardna and the Blue Zone towns. Now the two groups both claim rights to the database.
It's a complicated tale, with many murky corners, and it's worth reading the whole Guardian feature to follow its twists and turns as various companies go bankrupt, and the precious database containing blood samples from 13,000 Blue Zone inhabitants keeps changing hands. But as the Guardian rightly points out, the real issue is not which outfit should get to own the database, but the following:
The conflict has raised the kind of thorny ethical questions that are likely to become more pervasive as scientists tap into the promise of massive DNA databases to learn more about disease. Should a private company be able to profit from the study of a population’s DNA, when the DNA was voluntarily donated?
Needless to say, lawyers are now involved in resolving the more mundane issues of ownership of the Blue Zone blood samples. But even if a court hands down its judgment for this particular case, the larger ethical issues will remain, and become ever-more pressing as the importance and value of DNA databases continues to rise.
