Introduction to Breast Cancer Genetics at the University of Chicago


In 1990 I met Mary-Claire King, who at
that time was looking for the gene responsible for breast cancer and then
in 1994 we found that gene, it was called BRCA1. We thought it would be the only
gene that would be responsible for all of breast cancer and it turns out that
BRCA1 is one of many genes that when inherited in an abnormal form can lead
to increased risk for breast and ovarian cancer. We may now have an inherited form of BRCA1 or now BRCA2 and several other genes do not have to wait to
develop breast cancer ovarian cancer. With a simple blood test they can know
whether they are at high-risk. So when patients come to my clinic and work with genetic counselors who explain how these genes work and then we’ll help
women develop a proper management plan to manage their risk
