Alice Whittemore, a professor of epidemiology and biostatistics at Stanford University School and Medicine, and her colleagues included 86 known genetic variants that have been associated with breast cancer—including BRCA1 and BRCA2, which are relatively rare but confer a very high risk of disease compared to…
