Dr. Dan Roden of Vanderbilt University discusses the issues related to sharing genetic information with family members. Genetic test results that you may receive may have an impact on your family members, as they share much of your DNA. This involves making personal decisions that can be extremely complicated. Similarly, when genetic testing is done on large groups of individuals, this may have important implications for society as a whole.
Maureen Smith of Northwestern University recommends first discussing genetic test results with your doctor. Your doctor may refer you to a genetic counselor, who can help you understand test results and guide you toward brochures and websites that can provide information for both you and your family.
