Genetic Studies

Genetic testing involves examining your DNA, the chemical database that contains instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that can cause illness or disease. While genetic testing can provide important information for diagnosing, treating, and preventing disease, there are limits. For example, if you are a healthy person, a positive genetic test result does not always mean that you will develop a disease. On the other hand, in certain situations, a negative result does not guarantee that you will not have a certain disorder. Genetic tests play an essential role in determining the risk of developing certain diseases as well as screening and sometimes medical treatment. Genetic testing can also pose emotional, social and financial risks. Discuss all the risks and benefits of genetic testing with your doctor, medical geneticist, or genetic counselor before taking a genetic test. When genetic testing does not lead to a diagnosis but a genetic cause is still suspected, some facilities offer genome sequencing - a process for analyzing a DNA sample from your blood. Each has a unique genome, made up of the DNA of all of a person's genes. These complex tests can help identify genetic variants that may be related to your health. These tests are usually limited to examining the parts of the DNA that code for proteins called the exome.
