Testing for inherited susceptibility to breast cancer: a survey of informed consent forms for BRCA1 and BRCA2 mutation testing.

The identification of genetic mutations linked to breast cancer has made it possible to test for the genetic predisposition to this disease. However, though this test may provide certain benefits, there are also potential risks involved with the testing process, including social and economic considerations. In light of these potential risks, we sought to determine what information individuals are receiving in the informed decision making process. To learn the minimal amount of information the actual testees receive, we obtained 10 informed consent forms from seven different testing facilities. These testing centers include the major sources of BRCA1 and BRCA2 mutation testing in the United States at this time. We analyzed the content of these forms by developing content categories and scoring them appropriately. We found all ten forms discussed in varying ways and to varying degrees the purpose of genetic testing, limitations of the test, implications of both positive and negative results, and confidentiality procedures; most, but not all, addressed various psychological and insurance risks. Overall, the forms demonstrated substantial variation in content and organization, underlining the need for more discussion and research on the purpose, nature, and effectiveness of informed consent forms for this type of genetic test.
