Her story is expected to inspire other women to seek out genetic testing for cancer — but some will find themselves in a much less clear-cut situation.
After Jolie Pitt disclosed in 2013 that she carries a risk-increasing mutation in the gene BRCA1 and had undergone a preventive double mastectomy, researchers documented a surge in demand for genetic testing. They called it the “Angelina Jolie Effect”1. But not everyone who pursues genetic testing comes away with a definite course of action.
Thousands of possible mutations in BRCA1 and the related gene BRCA2 elevate a woman’s risk of developing cancer. But it is impossible to say whether many of these mutations predispose someone to cancer, because researchers simply have not seen them enough to know...
