BRCA1
BRCA1 DNA repair associated
BRCA1 helps repair broken DNA. Rare harmful changes in it greatly raise the risk of breast and ovarian cancer, and they are found by clinical genetic testing. The common variants listed on this page are not those rare changes.

Questions about BRCA1
Can a consumer DNA test find BRCA1 mutations?
Usually not reliably. Most consumer tests read a few positions at most, and a clear answer about BRCA1 needs a clinical test that reads the whole gene.
Are the BRCA1 variants on this page the risky ones?
No. The common variants here come from studies of large groups and shift risk only a little. The high-risk BRCA1 changes are rare and found by clinical testing.
