The Food and Drug Administration has authorized the first direct-to-consumer (DTC) test to report on three specific BRCA1/BRCA2 breast cancer gene mutations.
Personal Genome Service Genetic Health Risk (GHR) Report for BRCA1/BRCA2 (Selected Variants) does not identify the most common BRCA1/2 mutations but rather the three most common in people of Ashkenazi (Eastern European) Jewish descent, the FDA said in a press statement.
The test, marketed by 23andMe, analyzes DNA from a self-collected saliva sample.
The three mutations identified by the test are present in about 2% of Ashkenazi Jewish women, but rarely in other ethnic populations. Any individual who takes the test may have other mutations in BRCA1 or BRCA2 genes, or other cancer-related gene mutations that are not detected by this test.
“This test provides information to certain individuals who may be at increased breast, ovarian, or prostate cancer risk and who might not otherwise get genetic screening and is a step forward in the availability of DTC genetic tests. But it has a lot of caveats,” Donald St. Pierre, acting director of the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health, said in the press statement. “While the detection of a BRCA mutation on this test does indicate an increased risk, only a small percentage of Americans carry one of these three mutations and most BRCA mutations that increase an individual’s risk are not detected by this test. The test should not be used as a substitute for seeing your doctor for cancer screenings or counseling on genetic and lifestyle factors that can increase or decrease cancer risk.”
The authorization was based on data provided by the company to indicate the test correctly identifies the three genetic variants in saliva samples and is reproducible. In addition, the company submitted data to demonstrate that the instructions are comprehensible and easy to follow.
The FDA cautions that consumers and health care professionals “should not use the test results to determine any treatments, including antihormone therapies and prophylactic removal of the breasts or ovaries.” Decisions should be made only after confirmatory testing and genetic counseling, they said.
