Question

Quizplus · Accepted Answer

BRCA1 mutations alone are associated with an increased risk of breast and ovarian cancers but are not considered as tumorigenic as mutations affecting multiple tumor suppressor genes such as BRCA1, BRCA2, Her2, and p53 or the combination of BRCA1, BRCA2, and p53 mutations, which are associated with higher cancer risks. The addition of Her2 mutation further increases the risk.
