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.)
The Wild, Wild East of DTC Genomics and the Need for Meaningful Self-Regulation
Earlier this month CNN reported on the launch of a new program by the Chongqing Children’s Palace (CCP), in Chongqing, China, “that uses DNA testing to identify genetic gifts and predict the future.” In a story seemingly more appropriate for the Onion than for CNN, the article reports that Chinese scientists at the CCP are using the test, which is developed by the Shanghai Biochip Corporation, to “isolate eleven different genes” that will provide “information about a child’s IQ, emotional control, focus, memory, athletic ability and more.”
Shockingly, the CNN story expresses only the barest skepticism about the scientific claims made by CCP. Thankfully, Daniel MacArthur of Genetic Future, stepped in to provide a dose of clarity:
A quick note for any Chinese parents considering having this test performed on their children: you’re wasting your money (and we’re not talking small change – the test costs US$880).
The genetic variants that are currently known to affect traits such as athletic performance and height explain only a tiny fraction of the variation in these traits, so predictions made from genetic tests are extremely weak. In fact, for a trait such as height, parents can make substantially better predictions simply by measuring their own height than they can using the best that modern genetics has to offer…
…this is a scam, pure and simple, preying on parents’ willingness to believe in the power of science and to pay through the nose for anything they think might give their child an extra edge.
Although disappointing, the outlandish scientific claims made by CCP are unfortunately far from unique. Atlas Sports Genetics, which sells a $149 test that promises to predict a child’s natural athletic strengths, has been criticized for using genetic testing “to sell new versions of snake oil.” A Swiss-based DNA dating website, GenePartner, claims to measure the “genetic compatibility between two individuals and make[] an accurate prediction of the strength of their basis for a long-lasting and fulfilling romantic relationship” which, if true, would offer many a $99 insurance policy against vastly greater sums paid to divorce attorneys later in life.
