When Jenny Reardon was 11 years old, her father, a former Jesuit priest, told her, โJenny, genetics is the future.โ
Encouraged by her intellectually curious dad, she dove head first into the sciences, winning a prize from the General Motors International Science and Engineering Fair at age 14. Reardon double-majored in molecular biology and politics at the University of Kansas, and she fell into genomic research, as many molecular biologists did in the 1990s, before going on to get her doctorate. Now a sociology professor at UCSC, Reardon has authored her second book, The Postgenomic Condition: Ethics, Justice and Knowledge After the Genome.
An open letter from Reardon and 66 others argued that Reich dangerously misrepresented the science of genomics. I talked to Reardon, whoโs currently in Germany, about ethical issues around genetic studies and the fieldโs complicated relationship with raceโstemming partly from a history of white supremacy and eugenics. Reardon says that many people of color have been understandably hesitant to participate in research.
โWhen scientists have been interested in studying African Americans, itโs usually not because theyโre interested in improving their health,โ she explains. โItโs usually because theyโre a helpful research tool.โ
GT: What was your experience as a genomics researcher?
JENNY REARDON: I researched DNA when it was still pouring hot liquid between two plates of glass. It was not a very high-tech operation. Itโs helped people to take my work seriously. I knew the language of genetics.
What are you doing in Germany?
Iโm here with a group thatโs formed in Freiburg to address questions of human genetic variation research, and thereโve been some new developments in Germany. Ever since World War II, itโs been a taboo against using DNA to try to identify the population an unknown person comes from. If thereโs a criminal investigation into a cold case in the U.S., police would want to look at the DNA and say what race or population the person who committed the crime came from. In Germany, this has been illegal since 1997, but now theyโre talking about reversing it. Thereโs this group here made up of population geneticists, sociologists, and historians whoโre addressing this issue.
There was a death of a medical student here in Freiburg, and it launched the whole push to try to overturn the law because it was a cold case. They didnโt have any clues, and they wanted to be able to say, โOh, this person was from Turkey,โ or โThis person was from Syria.โ There are a lot of concerns about it, because it seems like itโs part of the backlash against immigrants.
Is testing for a suspectโs race a bad thing?
One of the first issues we took on at the Science and Justice Research Center, which I direct, came from a couple of grad students in a forensic anthropology laboratory. They came to me and said, โHey, weโve got a problem. Our job is to take these missing bodies the state of California brings usโsay for instance, people who cross the border, and they didnโt make it. But they donโt know who these people are. Theyโre missing people.โ
And they said to me that the state of California requires we assign a race to these bodies, but the database that was developed to do this work was developed in the American South, and the bodies they used were of people who have a different background. Itโs different parts of the world. They were saying, โWhen we do this, and we assign a race, weโre actually throwing ourselves off the trail because the database doesnโt represent the people that we see here.โ
So that gives you some sense of the problems of it. You can only say something about the ancestral background of someone if youโve sampled those people. The use of racial categories in genetics poses lots of serious issues. Historically, itโs not gone well when weโve used race to define people genetically.
After researchers sequenced the human genome, President Clinton touted the project for showing how much all people have in common. Will genomics do more to heal racial divisions or make them worse?
Weโve yet to see the answer. If itโs not going to make things worse, itโs going to require very careful thought about how genetics is interpreted.
Is it possible there are racial differences on the genetic level? Should we even want to know?
We have to remember that human beings created the concept of race, and human beings will always be deciding what it means and how it will be used. Genomics isnโt going to solve any of those things. It could aggravate or make them worse, because the problem is that people will too easily put genomics on a pedestal and say, โOh, the science tells us this,โ and forget that human beings made genomics. Human beings made the categories that human beings use.
What can a company do with someoneโs DNA data?
One of my chapters is about 23andme. 23andmeโif you read the fine print, which I did just do recentlyโthey ask you to spit in a tube, and ostensibly theyโre selling you information about you. But really what they want to doโand what their business plan has always beenโis use your data to create the largest DNA database in the world that will be of interest to pharmaceutical companies. That has always been its business planโbut itโs not, of course, what they lead with.
There are various levels of 23andme. You can just spit in a tube and theyโll send you your information. They then ask you if you will participate in 23andwe. And most people say โyesโ to this. They frame it as โHey, you can help other people.โ And most people want to help and do research. At that point 23andme can use your DNA for research purposes, although keeping people anonymous these days is technically difficult in genetics. They tell you that they wonโt release your data to the FBI or CIA, unless requested. It is legally possible that, once youโve spit in the tube, that the FBI or CIA can end up with that data should they decide that this was an issue of national security or something like that. 23andme is quickly becoming the largest DNA repository in the world, and the federal government would like to be able to identify every resident in the United States genetically.
The other thing people donโt understand is that once you spit in that tube and they send you back the information, they do things like tell you whether or not youโre at risk for breast cancer. You are then responsible for telling your insurance company, โYes, Iโm at risk for breast cancer,โ or youโre committing fraud. The importance of that in the United States is we have a law that says you canโt discriminate against people based on the genetic information when it comes to healthcare, but you can on long-term care or life insurance. People should think long and hard before they spit in that tube.
UCSC researchers led the push to sequence the human genome as quickly as possible. If they had moved too slowly, the private firm Celera would have tried to patent the entire thing. How would this conversation be different if that had happened?
We know a little bit about this because of the BRCA1 and BRCA2 [genes], which are the breast cancer genes. In that case, a company did patent it and did beat out the public effort. It was these two researchers from Utah who ended up creating a company, and that lead to Myriad Genetics. And Myriad Genetics cornered the market on BRCA1 and 2 testing until 2013, when the Supreme Court said gene patents are unconstitutional. To get your BRCA1 and 2 data you had to pay Myriad $3,000. BRCA1 and 2 is one of the few examples right now where the genetic information is, you could argue, very medically relevant. It has medical value, and for many, many years, women had to pay a high price to get access to that. Now the whole marketโs been opened by the overturning of the gene patents. All of these new companies have come into this space. 23andme is in this space. And you see all this competition. I donโt think it ever would have happened, that anyone would have let Celera patent the Human Genome. We probably would have seen the Supreme Court case come a lot earlier.
Itโs in nobodyโs interest to have genomic data under patent. Who was against Celera being under patent? The pharmaceutical companies. They did not want genomic data to be locked up under a patent because they werenโt going to make any money off genomic data. They were gonna make money off the things developed from genomic data.
Anything else I should be scared of in the future?
I hate that framing! We shouldnโt be afraid of genetics. We should be informed about geneticsโnot put it up on a pedestal. The whole reason I wrote this book was to make the field of genomics more accessible to people so they could join in the conversation and not treat it like itโs some high priesthood, that you have to have some fancy degree or that you need to be some kind of really smart scientist in order to understand it and to participate.
