FDA to Permit Marketing of Direct-to-Consumer Tests for Genetic Health Risks
In a reversal of previous policy, the FDA has announced it will allow the genetic testing company 23andMe to market its DNA tests directly to consumers.
In a reversal of previous policy, the FDA has announced it will allow the genetic testing company 23andMe to market its DNA tests directly to consumers.
“Consumers can now have direct access to certain genetic risk information,” said Jeffrey Shuren, MD, director of the FDA’s Center for Devices and Radiological Health, in the announcement. “But it is important that people understand that genetic risk is just one piece of the bigger puzzle, it does not mean they will or won’t ultimately develop a disease.”
The fear that consumers will misinterpret the test results led to the FDA's 2013 decision to bar marketing of 23andMe’s tests. The agency said at that time that 23andMe had not shown that the tests were accurate and that customers understood the results,
The tests work by analyzing DNA from a saliva sample for genetic variants associated with a higher risk of developing 10 diseases, including Parkinson’s disease, late-onset Alzheimer’s disease, and celiac disease. The FDA’s announcement cautioned that users should not interpret the results as a diagnosis or a basis for making treatment decisions, but acknowledged a study that found the tests’ directions and reports were easy to follow and that users understood over 90% of the content in the reports.
The announcement noted that diagnostic genetic tests are “excluded from today’s marketing authorization and any future, related exemption.” Examples of diagnostic tests include the test for the BRCA mutation, which some women have used to decide whether to undergo preventive mastectomies or other surgeries to lower their risk of cancer.
A notable figure who had previously argued against the FDA’s prior policy on 23andMe’s tests is Scott Gottlieb, MD, who is now poised to lead the agency pending Senate confirmation. In 2013, the American Enterprise Institute published
“The agency is trying to regulate mental responses to the data supplied by the tests — how others interpret or decide to act on accurate science,” Gottlieb wrote. “Dodging the First Amendment requires more than loose speculation about the possibility that the molecular scripts of life are too subtle and important to be read with impunity by the masses.”
This week, 23andMe reinforced the idea that consumers have the right to interpret their own genetic code as it heralded the FDA’s decision as a substantial step towards a more patient-centered approach to the field of genetics.
“This is an important moment for people who want to know their genetic health risks and be more proactive about their health,” said Anne Wojcicki, chief executive officer and co-founder, in
