Genetic testing is a powerful tool that examines changes, known as mutations or variants, in your DNA. This testing has far-reaching applications in the field of medicine, influencing the care you or your family members receive. For instance, genetic testing can lead to a diagnosis of a genetic condition, such as Fragile X syndrome, or provide critical information regarding your risk of developing cancer. There exists a diverse array of genetic tests, all of which involve the collection of a blood or saliva sample, with results typically available within a few weeks. Since genetic information is shared within families, if you're found to have a genetic alteration, it's essential to consider the potential implications for your relatives. Genetic counseling, both before and after testing, plays a pivotal role in ensuring that the right person in your family undergoes genetic testing, receives the appropriate test, and comprehends the results.
