Predisposition Biomarkers

Overview

A genetic predisposition (also called genetic susceptibility) is an increased likelihood of developing a health disorder based on the presence of a particular biomarker.  For example, the presence of the BRCA1 and/or BRCA2 genes indicates that a patient has an increased susceptibility to breast cancer. Genetic testing for disease risk is often considered when someone has a personal or family history that suggests an inherited risk for a particular health condition, and when the results provide information that can help guide a person’s future medical care.
