CLICK HERE FOR WORD VERSION OF THE PRESS RELEASE BELOW Genetics Health Professionals Uniquely Trained to Coordinate Genetic Testing Direct-to-consumer (DTC) marketing of genetic tests has been increasing considerably over the past few years. DTC genetic marketing presents both opportunities and challenges. It increases the awareness of the public regarding their risks for hereditary conditions and risk reducing options such as screening and lifestyle modifications, while at the same time it may generate confusion and anxiety, or even false reassurance. There is also the potential for results of such testing to be misinterpreted or misused. This is especially true when testing does not involve the expertise of a health care professional. Geneticists and genetic counselors are uniquely trained to identify those who would benefit from genetic testing, educate those who undergo genetic testing and help prepare individuals for what they might learn from testing. Additionally, they can interpret complicated genetic test results with regard to their clinical implications. Myriad Genetics Laboratories, Inc. is currently running a DTC marketing campaign in Indiana and the surrounding states. Myriad is the only laboratory in the United States that offers BRCA1 and BRCA2 gene analysis. Mutations in these two genes are associated with an increased risk for breast, ovarian, and other cancers. It is estimated that only 5-10% of breast cancer is due to a mutation in one of these two genes. Similar marketing in other regions of the U.S. has drastically increased the demand for this type of genetic testing. It is therefore likely that primary health care providers will be approached with questions regarding testing for hereditary cancer and many of them will not have the knowledge and background to handle these inquires. Additionally, many of those concerned about their risks will actually have a low likelihood for hereditary cancer and may not be appropriate candidates for genetic testing. Professional organizations including the American Society of Clinical Oncology (ASCO), the National Comprehensive Cancer Network (NCCN), the Society of Gynecologic Oncologists (SGO), the National Society of Genetic Counselors (NSGC) and the Oncology Nursing Society (ONS) recommend pre- and post-test genetic counseling. This is an essential component to the process of genetic testing for hereditary cancer so that individuals may fully understand the benefits, limitations, and cancer risk reduction options. In addition, because family history can be complex and hereditary breast cancer may be caused by mutations in a gene other than BRCA1 and BRCA2, there are many situations where genetic risk evaluation and testing is complex. Finally, pre- and post-test genetic counseling is important to convey to the individual being tested that results from genetic tests have implications for the entire family, not just the person who is being tested. Geneticists, genetic counselors and other health care professionals trained in genetics are available to answer questions regarding genetic testing and to accept referrals for hereditary risk assessment and patient education regarding the benefits and limitations of genetic testing.
