How are the BRCA1 or BRCA2 mutations inherited?

0

Both men and women who carry a BRCA1 or BRCA2 mutation may pass that alteration on to their sons and daughters, whether or not they are diagnosed with cancer themselves. Not all children of people who have an altered gene will inherit the alteration, and not all of those who inherit the alteration will develop breast cancer in their lifetime.
