Testing BRCA1 variants reveals differences in breast cancer risk
Researchers at the Francis Crick Institute have tested thousands of possible BRCA1 mutations in mammary gland cells to shed light on which genetic variants confer a high risk of developing breast cancer. Research like this holds potential to improve how genetic results are interpreted in the future.
