Andrea Beleno would rather be doing most anything else than meeting at Austin's Cherrywood Coffeehouse on President's Day to tell how, as she sees it, the State of Texas flat-out stole her son's DNA. With a career in nonprofit legal services, Andrea sees herself more as an advocate for others, not as an activist. Still, as her son Joaquin does his parka-toddler walk through the café courtyard with his fake Blackberry, she outlines how it all went down, blending one-part concerned mom with one-part sound-bite-savvy lawyer.
Before he became a DNA privacy poster child, Joaquin was just like any other child born in Texas since 2002. When hospital staff pricked his heel shortly after birth in 2008, the childhood disease-testing factory began processing his blood. Five droplets landed on the circles of a special DNA-preserving filter paper. His pediatrician repeated the test a few weeks later. Two spots on each card were used for the kinds of time-sensitive testing few people argue against, for life-threatening disorders as well as phenylketonuria (PKU), which can lead to brain damage if untreated. The state, which began its infant testing program in 1963, now screens for 29 disorders. But what happened to Joaquin's other three blood drops? Andrea certainly didn't ask while in the hospital. Foggy from pain meds, she doesn't remember much about the three days there. Later, at the pediatrician's office, she heard the "no news is good news" reassurance about the testing and forgot about it.
In fact, Andrea and her father-in-law, civil rights attorney Jim Harrington, didn't even consider the leftover blood spots until early 2009 when the medical reporter at The Austin American-Statesman uncovered the state program to collect baby DNA. The paper's report was a shock to the two of them: For almost seven years, the state had been taking the blood of most newborns in Texas — and storing it without parental consent — for "possible use in medical research."
Incredulous, Andrea and Jim didn't just grouse to friends and family. With Andrea as lead plaintiff, the Texas Civil Rights Project filed suit against the Texas Department of State Health Services and the Texas A&M Health Science Center, which had stored the samples since 2005. The suit charged the state with violating the children's Fourth and 14th Amendment rights, conducting unlawful search and seizure, and violating their privacy rights by collecting and indefinitely storing the cards without consent. Andrea and Jim's group wasn't the first to sue over infant blood sample collection — Minnesotans were — but the Texans were the first to win a settlement, and in surprisingly rapid time, by Christmas 2009.
The settlement, which included no financial payoff for the plaintiffs, ordered the state to destroy more than five million samples of baby DNA taken over a seven-year period and to disclose how the samples were used. Afterwards, Dr. Nancy Dickey, president of the Texas A&M Health Science Center and vice chancellor for health affairs of the Texas A&M System, lamented the loss of "a superb database" with the power to illuminate the causes of congenital birth defects. But the Texas Legislature, realizing they had a potential problem, acted quickly.
Even before the settlement, legislators voted overwhelmingly to require notification and allow parents to opt-out of the post-screening testing program. Since mid-2009, when the state was required by the new law to give new parents a disclosure form, only 7 percent have chosen to opt out of the program. For parents who want to support medical research that might come from the spots, the health department's website offers reassurance that blood samples given to researchers are "de-identified" so that recipients "cannot trace the specimen back to the baby from which it came."
Texas had 120 days after the agreement to destroy any infant blood samples in storage before May 27, 2009, unless given written parental consent to save them. The state was not, however, required to announce when the destruction would take place. As it turns out, while Andrea was enjoying her yerba maté and Sol Taco last February 15, two-and-a-half semi-trucks of 5.3 million infant blood spot samples left A&M's storage facility in College Station and the Texas State Health Department lab in Austin on their way to a medical incineration facility in the small town of Anahuac, near Houston. There, the samples were quietly, and without publicity, burned some time later.
THIS STORY GOES BEYOND ANDREA and the four other Texas families that filed suit against the state over the clandestine program. It gets to the heart of DNA. Who owns it? Who can access it? What does it reveal about us? How could it be used against us? What do scientists get out of our blood discards anyway? Beleno et al v. Texas Department of State Health Services et al and its aftermath is the latest skirmish in the age-old battle between privacy rights and the public interest. It's also (depending on which blogger is arguing) a modern-day case study of duplicitous government or ignorant anti-science extremism. As it turns out, the court settlement was far from the end of the story, with the military in a last-minute role.
Science writer Rebecca Skloot isn't shy about saying that the Texas settlement was "huge." She knows. She spent 10 years covering the story of a dying woman's cells taken without consent nearly 60 years ago. The resulting cell line is still reaping rewards for medical researchers. It might surprise the average person, but according to Rebecca's bestseller, The Immortal Life of Henrietta Lacks, most Americans today have tissue on file somewhere. It's just that Henrietta's cells have proven more powerful than average.
Henrietta Lacks, a poor black tobacco farmer, died in 1951 of an aggressive cervical cancer. Her doctor gave some of her cancerous tissue from a biopsy to a researcher to see if it would grow in a culture, a common practice at the time that was usually unsuccessful. But Henrietta's cells multiplied like mad, providing generations of scientists with cellular powerhouses that helped develop screening and treatment breakthroughs for cancer, polio, and sexually transmitted diseases. They were even sent on the space program's earliest missions to understand how cells operate in zero gravity. Known as HeLa for her first and last names, these cells have become both foundation and lore in the medical community. They are also a big business. Rebecca says the now multibillion-dollar HeLa industry sells vials of these cells — pieces of a woman who never consented to anything but a medical procedure — to the research community for sums ranging from $200 to $10,000.
In her book, Rebecca writes about the shock most people experience when they learn about Henrietta. "When I tell people the story of Henrietta Lacks and her cells, their first question is usually Wasn't it illegal for doctors to take Henrietta's cells without her knowledge? Don't doctors have to tell you when they use your cells in research? The answer is no — not in 1951, and not in 2009, when this book went to press." Rebecca tells the story of a man who sued his former doctor in the 1980s for trying to patent cells from his spleen, which was removed due to leukemia. The case finally ended up in the Supreme Court of California, which ruled that the patient had no rights to the tissues after they left his body. She cites another case in 2005 over the rights to prostate cancer samples stored in a tissue bank at Washington University. Courts ended up ruling for the research institution, not the patient. That's why the Texas settlement — and the order to destroy the samples — is significant.
DNA IDENTITY TESTING PIONEER Art Eisenberg is baffled by the Texas parents' case. These blood spots, he says, are the best DNA source for solving missing persons cases, providing what he repeatedly, if hesitantly, calls "closure" for parents. Art is director of the University of North Texas Center for Human Identification at the Health Science Center. When he hears the samples have been destroyed, he shakes his head and calls it "a travesty."
"Let's say you went missing and they can't find your family," he says as a way of personalizing the DNA issue. Or, "if you've been murdered." This is when his lab steps in, matching DNA samples to identify the remains and possibly catch a criminal. Direct matches are the best. That's where the infant blood spot card comes in. If preserved well, the blood spots provide the most direct link to the missing person. When close family members cannot be located to provide a cheek swab, his lab "suggests" to law enforcement that an infant blood spot card would be the best reference sample. For whatever reason, they rarely receive the cards. Sometimes, they just can't be found.
When they do receive them, the blood spot samples come in as "punches" with only the material needed for identification. Security measures set up through the FBI's CODIS — or Combined DNA Index System — provide for a tightly protected local database that feeds a national database with less detailed information.
Although Art focuses on identifying missing persons, examining only the slice of data he needs, he understands the privacy risks of DNA research. "Let's say I get a blood card or a spot, a tiny piece of paper with your blood on it, no name — for whatever reason, one of your siblings or your parents are in a database — theoretically, I could identify you even though that card was given to me in an anonymous [way]," he says, "but that's not specifically what we do."
Art leisurely discusses the science of DNA, the intrigue of resolved cases, the structure of databases. He is not overly clinical in manner, but when he talks about the destruction of the samples, he borders on the emotional. "They never really thought through how those samples could be used to help, to help families with a missing loved one," he says. He feels that the samples' destruction might create a new reality where family members have no way of knowing what has happened to their loved ones.
But when he learns about the plaintiffs' concerns over informed consent, he pauses and sits up straight. Everything they do in his office revolves around signed consent. The samples they get from family members have the proper signatures on the proper forms. "If those neonatal cards have been used by some other entities for doing something that either the individual, if they are of legal age — or the family, the parent — were not aware of and did not provide consent, I too would have a problem with that," he says.
THE BLOGOSPHERE AND MESSAGE BOARDS started humming the minute news of the Texas settlement broke. Some sided with Andrea, or thought they did. "Big Brother is in your DNA!" Loving Truth! commented on ScienceMag.org. Cyperstooge blamed "corprofascist military industrial stooges," adding that "It amazes me that the parents of these kids haven't gone totally crazy on these people." But reaction was divided early on: "The destruction of this database is a tremendous loss for science and the citizens of Texas, and a victory for lawyers and the anti-science, pro-stupid lobby," Consilience wrote on the Statesman's website. No Worries weighed in, too: "Once again the paranoid few trump the good of science." Some debated, some all-caps argued, and some tracked Andrea down by Google and barged into her work time with hate e-mails.
Andrea bristles as she describes portrayals of herself and other plaintiffs as anti-screening program, anti-government, anti-science extremists. She is irritated by critics claiming she is against all screening. "Until I had a child, I had no idea that the infant testing program existed. I'm glad that it does," she says.
When she participated in medical studies to pay for college, however, she remembers signing numerous consent forms and wonders why baby blood collection and — more importantly — storage for future use would not require the same. "To piggyback the warehousing of the genetic information of every person who is born here on something as important as screening is a breach of faith," she argues.
While admittedly a layperson trying to understand complex scientific issues, Andrea questions the value of the de-identified blood spot, removing valuable information, such as geographic region or gender, which could be of use to researchers. She wonders how much can be gleaned from the DNA itself after stripping away identifying data. On the other hand, Andrea points to a TV segment she saw about an ancient man in Greenland who died 4,000 years ago. By extracting DNA from his hair, scientists could determine eye color, hair thickness and susceptibility to disease. "And you're telling me you can't get identifying information out of my kid's blood spot?" says Andrea.
She has concerns with the new Texas law, too. She would prefer that parents could opt-in, rather than opt-out. She wasn't surprised when a list of studies, published on the health department website in January, revealed that 800 of the spots were used for forensics. Mixed in with studies to help understand deafness, cleft palate and childhood cancer were two projects by the Armed Forces to enhance "the size, sampling, and quality of forensic mtDNA databases." The Armed Forces DNA Identification Laboratory (AFDIL) has been using this mitochondrial DNA, or mtDNA, to help identify the remains of military personnel for some time — a fact widely known in forensic circles.
To Andrea, the complexities surrounding this issue can obscure the point. "It's not about politics, it's not about science, it's about consent and it's about parents' responsibility to make decisions for their kids," she says. Ironically, she would have willingly consented if they had asked her permission. Now, however, she distrusts the government. "Once you have a state agency that will bold-faced lie to you once," she says, "you don't know what else they might be lying about."
If Andrea has another baby, she says, "There is no way I would consent to having my kid's DNA be part of the sample because I just don't trust 'em." |
