On March 6, 2018, the US Food and Drug Administration (FDA) granted the first marketing authorization to 23andMe, a personal genomics and biotechnology company, for a direct-to-consumer (DTC) genetic test: testing for 3 BRCA1 or BRCA2 mutations to identify women at increased lifetime risk of breast cancer.1 The FDA granted authorization based on the accuracy and reproducibility of the test for 3 BRCA mutations that are most common in people of Ashkenazi Jewish descent, but which also occur in the general population. 23andMe hailed the decision as a “milestone in consumer health empowerment,”2 allowing women to test for common BRCA mutations. Consumers simply mail a swab of saliva to 23andMe and receive results in 6 to 8 weeks at a cost of $199.3
