Zach and Stephanie want to have a child, but they are concerned. Stephanie's grandmother and mother both died of breast cancer, and Stephanie has been tested and found to have the gene for this fatal condition. Having a child does not ensure that the illness could be passed, but they want to reduce the risk of passing on this gene to their child. What technique might be used to achieve this goal?

Question

Preimplantation genetic diagnosis (PGD) can be used to identify embryos that do not carry the gene for breast cancer before they are implanted in the uterus. This can greatly reduce the chances of passing on the gene to the child. Karyotyping, embryonic genetic manipulation, fetal genetic cloning, and creating a "savior sibling" are either not relevant or not currently feasible options for reducing the risk of passing on the breast cancer gene.
