Why 23andMe’s Sample Swap is Actually an Argument In Favor of DTC Genetic Testing
Direct-to-consumer (DTC) genetic testing company 23andMe made news this week thanks to a lab mix-up that left up to 96 customers reviewing genetic data that was not their own. Full details of the mix-up, and analysis of 23andMe’s response, are available from Daniel MacArthur at Genetic Future and Turna Ray at Pharmacogenomics Reporter.
23andMe’s sample swap follows close on the heels of the FDA announcing an investigation into Pathway Genomics and Congress launching an even broader investigation of the three leading DTC genetic testing providers. Not surprisingly, many commentators have pointed to 23andMe’s mix-up as just the latest example of the dangers of DTC genetic testing and further evidence of the need for greater federal regulatory scrutiny.
There are a number of reasons why DTC genetic testing may soon find itself subject to increased federal regulatory oversight. However, 23andMe’s widely publicized data error should not be one of those reasons. In fact, the sample swap, while unfortunately timed, actually presents a compelling argument in favor of the direct-to-consumer model for genetic testing.
Evaluating the NIH’s New Genetic Testing Registry
This morning the NIH announced plans to create a publicly accessible registry of genetic tests. The Genetic Testing Registry (GTR) is expected to be available in 2011 and will contain information voluntarily submitted by genetic test providers. The news is significant and carries implications for clinical genetic testing laboratories, personal genomics service providers and individual purchasers of genetic tests.
Many details of the GTR are yet to come, with NIH promising to “engage stakeholders – such as genetic test developers, test kit manufacturers, health care providers, patients and researchers – for their insights on the best way to collect and display test information.” While the GTR isn’t expected to launch until next year, and there is time to fill in the details, the questions and answers section of the GTR’s new website helpfully addresses several of the most important features of the registry.
This post looks at what we know about the GTR today, and considers what the GTR’s ultimate implementation might mean for the development and regulation of genetic testing. (Note that the inset orange questions, and the text that immediately follows each question, is taken directly from the GTR question and answer page.)
