Precision assessment of public attitudes toward genetic testing.

Public attitudes toward genetic testing are largely unknown. Furthermore, as medical practices vary widely among different regions around the world due to differences in cultural, sociopolitical, and economical environments, people from different regions may have drastically different attitudes. Even for the same individual, the attitude may vary depending on the purpose and type of genetic testing and the disorder to be tested for. It seems to me what is called for is a "precision" approach to gauging people's attitude toward genetic testing. In the current issue of the American Journal of Medical Genetics: Part A, Fu et al. reported a carefully designed study that began to fill this gap, although more work need to be done for different disorders and among other populations. © 2016 Wiley Periodicals, Inc.
