DNA DTC: The Return of Direct to Consumer Whole Genome Sequencing
This morning, Gene By Gene, Ltd. – better known as the parent company of the popular genetic genealogy provider Family Tree DNA – formally announced a corporate reorganization that includes the debut of a new division, DNA DTC. (Apparently the news was also announced earlier this month at the Family Tree DNA Conference, although the company waited until today to launch press releases.)
The announcement from Gene By Gene is newsworthy for several reasons, including:
1. The Return of True DTC Whole Genome and Whole Exome Sequencing. According to DNA DTC, the company offers a range of products “utilizing next generation sequencing including the entire exome (at 80x coverage) and the whole genome.” The company’s website, while fairly spartan, appears to bear this out. Whole exomes ($695 at 80x coverage) and genomes ($5,495 at 30x coverage) are both listed as available products.
Now, Gene By Gene is not, as its Wikipedia page claims (as of this writing), “the first commercial company to offer whole genome sequencing tests.” Knome earned that honor more than four years ago, when it started selling whole genome sequences for $350,000; an astounding price, either low (given the cost of the first human genome was $3 billion) or high (given that, well, it was $350,000) depending on your perspective. Gene By Gene probably does represent, however, the only commercial company currently offering a whole genome sequence in a truly direct-to-consumer (DTC) manner.
The Past, Present and Future of DTC Genetic Testing Regulation
[Editor’s Note: Newsweek science editor Mary Carmichael has a DNA Dilemma. As Carmichael debates whether to take a direct-to-consumer (DTC) genetic test, she is soliciting feedback from the DTC community, from the public and from other commentators, including myself. At the end of the week, she will make her decision.
On Tuesday, Carmichael and five commentators examined what can be learned from a DTC genetic test. Yesterday, the topic was whether DTC genetic tests are trustworthy, and whether the results can be cause for concern. Today’s topic is the regulation of DTC genetic tests. In addition to several short commentaries, including a much shorter version of the piece below, Carmichael has also posted a lengthy interview with two top FDA officials on the subject of DTC genetic testing regulation.
The column below is an expanded version of what appears over at Newsweek. To see all of the commentaries in Carmichael’s series, click here.]
The recent media attention focused on direct-to-consumer (DTC) genetic tests has left companies, investors, consumers and even regulators scrambling to figure out what comes next.
As the situation stands today, companies and their investors live in a climate of unprecedented regulatory uncertainty, causing delays in the introduction of new products and rendering an already inhospitable economic climate – for both fundraising and sales – even more challenging. Commentators and regulators caution consumers that some DTC genetic tests may be unreliable or, worse, harmful, but have yet to provide clear tools and guidelines for evaluating competing tests. And regulators, including the FDA, must balance their mandate to protect the health and safety of the public with that same public’s desire for autonomy, while also recognizing that innovation is a prerequisite for a healthcare system that must continue to improve outcomes while reducing costs.
Clearly, something must change. But what will that change be? And how will the field of DTC genetic testing evolve? Will DTC be able to continue its current business while regulators and companies engage in protracted negotiations? Will oversight weed out the “snake oil salesmen” and permit legitimate companies to flourish? Will it drive all genetic testing (temporarily) out of the hands of consumers?
Or will the field change in a dramatic and completely unexpected way?
While You Were Meeting: FDA Mails Letters to 14 More Genetic Test Providers
Earlier this week the FDA held a widely publicized two-day public meeting to discuss its planned regulation of laboratory developed tests (LDTs) (for more see: Day One Recap and Day Two Recap). Other than Monday morning, when the FDA presented background information on LDTs and some of the considerations that have pushed the Agency to pursue a “risk-based application of oversight to LDTs,” the top Agency officials at the meeting were conspicuously quiet. Elsewhere, however, the FDA was doing plenty of talking.
In letters dated July 19th, the first day of the FDA’s public LDT meeting, the Agency continued its crackdown on direct-to-consumer (DTC) genetic test providers, mailing letters to 14 providers of genetic tests. A list of all 14 companies and tests appears below.
Challenging the FDA: A History Lesson for DTC Genetics
Last week the FDA sent letters to five personal genomics companies alleging that the companies are manufacturing and selling medical devices without appropriate FDA review. The FDA’s decision to substantially increase its regulatory oversight of some of the most prominent direct-to-consumer (DTC) genetic service providers has met with a mixed reaction. Supporters of the move argue that these DTC products are medical in nature and require more stringent regulatory controls. Critics, including at least one of the companies receiving a letter (23andMe), fault the FDA for adopting a paternalistic stance to personal genetic information and imposing unnecessary regulatory controls.
What’s Next for DTC? In last week’s post, we outlined several possible responses available to DTC genetics companies, including (1) pulling products from market, (2) agreeing to comply with FDA regulatory requirements, (3) modifying products to avoid FDA oversight or (4) challenging the FDA’s regulatory authority over DTC genetic testing products. We also noted the possibility that the FDA’s decision to look more closely at DTC genetic tests could presage increased scrutiny of the genetic testing industry more broadly, including the many tests currently offered without FDA clearance or approval as laboratory developed tests (LDTs).
What Five FDA Letters Mean for the Future of DTC Genetic Testing
The FDA has published online letters sent to five personal genomics companies – 23andMe, Navigenics, deCODE Genetics, Knome and Illumina – informing the companies that they are manufacturing and selling medical devices without appropriate FDA premarket review and approval. No surprise that the news that the FDA has sent out letters to some of the most well-known providers of DTC genetic testing products is already making waves. (Daniel MacArthur was the first to point me to the AP story, and Mary Carmichael of Newsweek and Andrew Pollack of The New York Times were among the first to dive into the substance of the letters.)
Below, we will discuss the immediate and long-term implications of the FDA’s most recent regulatory actions for the five companies receiving letters, as well as for the DTC genetic testing industry. First, however, a review of the letters themselves is required. Each of the five two-page letters is signed by Alberto Gutierrez, Director of the FDA’s Office of In Vitro Diagnostic Device Evaluation and Safety (OIVD), and follows a similar format throughout. To gauge the impact of these letters we will take them paragraph by paragraph.
Mapping the Personal Genomics Landscape
Last week saw the first annual Genomes, Environments, Traits (GET) Conference, in Cambridge, Massachusetts. Timed to coincide with DNA Day 2010, the conference marked one decade since the publication of the draft consensus human genome sequence. The GET Conference was billed as “the last chance in history to collect everyone with a personal genome sequence on the same stage to share their experiences and discuss the important ways in which personal genomes will affect all of our lives in the coming years.” Not quite everyone with a public personal genome sequence attended – Craig Venter, Desmond Tutu, Glenn Close were all unavailable – but a majority of the genomic pioneers were in attendance and the GET Conference was a one-of-a-kind event.
For those who missed the GET Conference, several high quality recaps are available. The most detailed is A Day Among Genomes, by Carl Zimmer of Discover’s blog The Loom. More targeted reflections on the conference and related events come from Emily Singer of Technology Review summarzing key trends highlighted by the genome pioneers (Singer also has a related piece on the difficulties of understanding human genomes), David Dobbs of Neuron Culture on genomes, cool conferences, and what the hell to tell people about behavioral genes, and Turna Ray of Pharmacogenomics Reporter on the recent Myriad Genetics decision, and its impact on the business of patenting genes. If you’d like even more detail, the Twitter community provided real-time play-by-play.
While there’s no need for a further summary, the GET Conference does provide an occasion to look at the evolving personal genomics landscape in a more holistic fashion.
Another Stop on the Road to the $1,000 Genome
The latest stop on the road to the $1,000 genome? San Francisco, CA, where J.P. Morgan’s 28th Annual Healthcare Conference is in full swing. There is an abundance of real-time Twitter coverage from the conference, but certain announcements warrant a more detailed discussion.
The announcement generating the biggest buzz today came from Illumina, Inc., whose CEO Jay Flatley unveiled a new genome sequencing machine, the HiSeq 2000. According to Matthew Herper of Forbes.com, Illumina’s new machine “will decode a person’s DNA in one week using $10,000 worth of materials – five times cheaper than any other competing gadget on the market.” Herper adds that the machines will begin shipping in February with a cost of $690,000 (compared to $500,000 for Illumina’s current model). Illumina’s own product page for the HiSeq 2000 provides more technical details, including coverage (~30x) and read length (2×100 bp). There have also been unconfirmed rumors that the machine will come equipped with an iPhone user interface, a concept that Flatley first pitched at last summer’s Consumer Genetics Show.
If it performs as advertised, the HiSeq 2000 is likely to be a huge hit with large genome sequencing centers, as evidenced by the announcement that the BGI (formerly the Beijing Genomics Institute) has agreed to purchase a whopping 128 of the new sequencing systems. But what, if anything, does the Illumina announcement mean for individuals consumers interested in receiving a complete genomic sequence?
Federal Privacy Regulation and the Financially Troubled DTC Genomics Company
Last month, the Genomics Law Report prepared a three-part series entitled What Happens if a DTC Genomics Company Goes Belly Up? The series, which was originally published on Genetic Future (see Parts 1, 2 and 3), reviewed the privacy policies of several genomics companies to determine whether they prohibit the transfer of private data to third parties. We also discussed the fact that a bankruptcy court may approve such a transfer notwithstanding a policy to the contrary. In this post, we examine whether federal regulations may restrict the dissemination of private genomic data—including the new rules proposed earlier this month under the Genetic Information Nondiscrimination Act of 2008.
1. Is DTC Getting HIPAA? The Health Insurance Portability and Accountability Act of 1996 (HIPAA), the most prominent federal regulation governing the privacy of medical records, established the Privacy Rule to provide national standards for protected medical records. HIPAA’s Privacy Rule currently applies only to “covered entities” and business associates of covered entities. A covered entity is a health plan, health care clearinghouse, or a health care provider. Since a company providing genomic sequencing services is not a health plan or a health care clearinghouse, HIPAA will apply only if such a company is determined to be a health care provider or a business associate of a covered entity.

The Scientific Foundation for Personal Genomics: Recommendations from the Joint NIH-CDC Workshop
Last December, some of the true heavyweights in the field of personal genomics convened for a two-day workshop cosponsored by the CDC and NIH to review the science and implementation of personal genomics. Participants included scientific luminaries (e.g., Francis Collins, George Church and Bob Green), personal genomics companies (e.g., 23andMe, Knome, Navigenics, deCODE Genetics and DNA Direct) and policy groups (e.g., Genetic Alliance, Personalized Medicine Coalition and Genetics and Public Policy Center). The workshop and its participants’ recommendations were summarized (pdf) late last month in the journal Genetics in Medicine.
The workshop focused on a review of the “scientific foundation for using personal genomics in risk assessment and disease prevention,” developing five specific recommendations for the future development and use of personal genomics.
1. Develop and implement scientific standards for personal genomics. Of primary importance was the development of scientific benchmarks for evaluating personal genomics testing. Heavily emphasized was the need to establish standards for measuring the clinical validity (how well a genetic variant identifies or predicts an individual’s clinical status) and clinical utility (the health and other benefits of a test balanced against its harms or costs) of personal genomics tests. The importance of voluntary industry guidelines (pdf), randomized clinical trials and economic analysis of personal genomics testing were all discussed.
Whole-Genome Sequencing and Gene Patents Coexist (For Now)
In a recent post, John Conley analyzed the ACLU’s lawsuit challenging Myriad Genetics’ patents on the BRCA-1 and BRCA-2 “breast and ovarian cancer susceptibility” genes. Several readers responded with the same general inquiry: if an individual undergoes a whole-genome sequence analysis, will the individual (or the company providing the sequence) be required to pay royalties to Myriad because the BRCA-1 and -2 loci will have been sequenced?
Although focused on the BRCA genes, the question is broadly applicable to the entire genome sequencing industry: when sequencing all or a portion (e.g., the exome) of an individual’s genome, are individual gene patents infringed upon by either the company providing the sequence or the individual purchasing or requesting it? The answer is not entirely clear, but, at least in the case of Myriad and the BRCA genes, it appears to be no. Or at least, not yet.
Let’s begin with what is not patented, which includes a majority of genes and the vast majority of the human genome. Genes—those stretches of DNA that encode for proteins—make up approximately 2% of the human genome. The estimate of the exact number of genes ranges from between roughly 20,000 to 30,000 and, of those, a 2005 study in the journal Science found that only 20% of human gene DNA sequences are patented (subscription). Although those numbers are certainly subject to change, the reality is that, today, it is likely that less than 1% of the entire human genome has been patented.
Of course, that very small number belies the fact that the genes which have been patented consist of some of the most important identified genes associated with the prediction or determination of human health and disease. The high-profile BRCA genes are an excellent example and thus make for a good case study.
