Family Patterns for BRCA 1 and BRCA 2 Mutations
Having an inherited mutation in the
BRCA 1 or BRCA 2 gene means that this person possesses an altered gene from one of your parents. Either parent can be a carrier of the altered gene, and assuming only one of your parents carries the mutated form, your siblings will also have a 50 percent chance of inheriting the
mutated gene. If you are a carrier, your children would face the same risk. However, it is important to remember that having the mutated gene only puts someone "at risk" for developing breast cancer. Altered BRCA 1 or BRCA 2 genes, does not mean breast cancer is definitely in your future, but regular screening measures should be taken.
