Lab Test May Identify Dangerous Gene Mutations, Study Finds

September 12, 2018

(ABC News) – Scientists say they’ve found a new way to help determine whether specific genetic abnormalities are likely to make people sick, a step toward avoiding a vexing uncertainty that can surround DNA test results. Researchers used genetic engineering to create thousands of tiny variations in a gene linked to breast cancer, and tested each one in a lab to predict whether it would promote the disease if it appeared in a person.
