HER2 receptor. These days those with breast cancer that overexpresses this growth factor receptor tend to get monoclonal antibodies against it, which both suppress its growth effects and tag it for disruption by the immune system.
Yes, this is a protein test rather than a genetic test. But it lets the subset of people with this amplification get a treatment that has a large positive absolute effect on those with early-stage cancer.
