The Lancet Oncology
I am employed by 23andMe in the company's communications group.
We read the Lancet Oncology Editorial with interest.1
Although there are several important topics to debate regarding
direct-to-consumer genetic testing, the authors missed an opportunity to
address them. Rather, they conflate two separate issues: the regulation
of prescription medication marketing, and the regulation of
non-diagnostic direct-to-consumer genetic testing.
The
Editorial discusses proposed legislation to end tax breaks given to drug
companies for marketing prescription drugs directly to consumers. The
juxtaposition of this legislation with the discussion on #23andMe
suggests a connection between the proposed law and direct-to-consumer
genetic testing regulation, when in fact the two are unrelated.
Direct-to-consumer genetic testing is subject to regulation by the US
Food and Drug Administration (FDA) and various state agencies, and does
not receive any tax deduction for marketing.
In addition
to decoupling these issues, the Editorial would benefit from painting a
more complete picture of the regulatory environment for
direct-to-consumer genetic testing. Although 23andMe was not wholly
banned from selling its product, it was mandated by the FDA to cease
marketing the health portion of its test in November, 2013. 23andMe
complied and engaged in a lengthy review process with the FDA, which
included thorough validation testing and consumer comprehension studies.
As a result, the FDA authorised the marketing of 23andMe's Bloom
Syndrome Carrier Status test report, and down-classified carrier status
testing as a category of direct-to-consumer genetic testing, therefore
exempting carrier testing from premarket review. 23andMe now offers the
only direct-to-consumer genetic service that includes reports that meet
FDA standards.2 Furthermore, 23andMe does not provide information on carcinogenic mutations, as cited in the editorial.
The
authors also raise questions about whether information gleaned from
genetic testing should be delivered directly to consumers. Although
there is always room for debate, evidence has been generated over the
past 5 years indicating that most consumers who purchase
direct-to-consumer genetic tests do understand the results they are
given.3
Additionally, and in direct opposition to assertions in the Editorial,
data included in 23andMe's FDA submission showed a more than 90%
comprehension rate of key concepts in its reports.4
Those results were generated in nationwide focus groups, which were
representative of the US population according to age, race or ethnicity,
and education.
Although direct-to-consumer marketing of
pharmaceuticals and direct-to-consumer genetic testing are two topics
that warrant further discussion, they are distinct issues that should be
treated as such to ensure the respective facts can be understood,
analysed, and debated. Other issues specific to direct-to-consumer
genetics raised by the editors, such as consumer privacy and physician
comprehension of genetic testing information, should be continually
discussed. We welcome these conversations as greater adoption of
direct-to-consumer genetic testing continues.
