Genetics

Predictive and presymptomatic testing

This type of testing is done to determine whether you have a greater chance of having diseases that usually show up later in life. If you have a relative who has the disease, information from these tests can help you make decisions about preventing or slowing the progress of the disease.

Genetic testing is used to identify the risk of diseases such as:

Breast cancer and ovarian cancer (BRCA-1 and BRCA-2 testing).
Familial adenomatous polyposis (FAP) , which causes abnormal growths inside the colon and increases your risk of colorectal cancer.
Huntington disease, a rare disease that causes premature, severe deterioration of the brain.
