Henrietta Lacks

New York Times OPINION, "The Immortal Life of Henrietta Lacks, the Sequel," by Rebecca Skloot, on 23 March 2013 -- LAST week, scientists sequenced the genome of cells taken without consent from a woman named Henrietta Lacks. She was a black tobacco farmer and mother of five, and though she died in 1951, her cells, code-named HeLa, live on. They were used to help develop our most important vaccines and cancer medications, in vitro fertilization, gene mapping, cloning. Now they may finally help create laws to protect her family’s privacy — and yours.

The family has been through a lot with HeLa: they didn’t learn of the cells until 20 years after Lacks’s death, when scientists began using her children in research without their knowledge. Later their medical records were released to the press and published without consent. Because I wrote a book about Henrietta Lacks and her family, my in-box exploded when news of the genome broke. People wanted to know: did scientists get the family’s permission to publish her genetic information? The answer is no.

HeLa cell

Imagine if someone secretly sent samples of your DNA to one of many companies that promise to tell you what your genes say about you. That report would list the good news (you’ll probably live to be 100) and the not-so-good news (you’ll most likely develop Alzheimer’s, bipolar disorder and maybe alcoholism). Now imagine they posted your genetic information online, with your name on it. Some people may not mind. But I assure you, many do: genetic information can be stigmatizing, and while it’s illegal for employers or health insurance providers to discriminate based on that information, this is not true for life insurance, disability coverage or long-term care.

“That is private family information,” said Jeri Lacks-Whye, Lacks’s granddaughter. “It shouldn’t have been published without our consent.”

Some scientists agree: Jonathan Eisen, a genomics researcher at the University of California, Davis, tweeted, “A bit stunned that the people publishing the HeLa genome appear to not have gotten consent from the family.” Another said this was going to further damage public trust in science. A few argued that the cells had changed so much over time, they couldn’t accurately tell us anything about Lacks (to which a geneticist replied, “Your claim is so wrong that I don’t know where to start”). Several noted that consent wasn’t required to publish the HeLa genome (true). But over all, the scientific community was surprisingly silent on the issue.


On its own, the HeLa genome doesn’t say anything specific about Lacks: it’s a string of billions of letters that detail the genetic information that makes up a HeLa cell, which is useful for science. A news release from the European Molecular Biology Laboratory, where the HeLa genome was sequenced, said, “We cannot infer anything about Henrietta Lacks’s genome, or of her descendants, from the data generated in this study.”

But that’s not true. And a few scientists decided to prove it. One uploaded HeLa’s genome to a public Web site called SNPedia, a Wikipedia-like site for translating genetic information. Minutes later, it produced a report full of personal information about Henrietta Lacks, and her family. (The scientist kept that report confidential, sharing it only with me.) Until recently, few people had the ability to process raw genome data like this. Now anyone who can send an e-mail can do it. No one knows what we may someday learn about Lacks’s great-grandchildren from her genome, but we know this: the view we have today of genomes is like a world map, but Google Street View is coming very soon.


Scientifically speaking, that’s good news. There’s a lot of hope for using technology like this for affordable “personalized medicine.” But legally and ethically speaking, we’re not ready for it.

As Francis S. Collins, director of the National Institutes of Health, says: “This latest HeLa situation really shows us that our policy is lagging years and maybe decades behind the science. It’s time to catch up.” The regulations governing this sort of research were written in the 1970s, long before anyone imagined what you could learn from a bit of DNA. They are largely based on the now outdated belief that if samples are “anonymized” (i.e., your name is removed), there’s no need to get consent before using them in research.  [New York Times OPINION]
