Genetic testing and counseling are useful tools for patients with rare diseases.
Sophisticated genetic tests available in clinical settings now offer health care providers a closer look into patients’ genes. The information there may allow them to diagnose a hereditary condition, assess a patient’s risk for a particular disease or determine whether a certain drug might work.
Since the mapping of the human genome in 2003, more than 75,000 genetic tests have emerged, with about 10 new tests entering the market daily.
