Find Out if You Have a Hereditary Disease

DNA tests can also be used to detect hereditary diseases such as Huntington's disease, sickle cell anemia, Marfan syndrome, and others. In fact, more than 2,000 hereditary diseases can be diagnosed using DNA testing. These are diseases that are almost certain to develop if you have the associated mutation, regardless of your lifestyle or current health.

It is critical to be able to screen for these diseases using a DNA test. When you know you have the genes for a specific condition, you can work with your doctor to develop a health plan. Furthermore, even if you don't have the disease, you can find out if you're a carrier. If you are a carrier, a DNA test can tell you how likely you are to pass the disease's genes on to your child.
