People inherit two copies of each gene — one from each parent — an evolutionary fail-safe to ensure survival even when one of them doesn’t function. Likely not, according to the findings of a new ...

A study led by Harvard Medical School researchers shed new light on how even a single defective copy of the tumor-suppressor BRCA1 gene can increase patients’ risk of developing breast cancer.

University of Oregon biologists have uncovered a mechanism by which a well-known breast cancer gene also influences fertility. Mutations in the BRCA1 gene sharply increase a person's risk of ...

Harmful variants in the BRCA1 gene greatly increase a person's lifetime risk of developing breast, ovarian and pancreatic cancers, but most people are unaware they are carriers. In a new study in the ...
