Part II-A New Dilemma Suzanne and David decided that Suzanne would take the diagnostic test. In preparing for a possible positive result, they increased the value of Suzanne's life insurance and purchased the best long-term care policy available. They also prayed together and promised each other that the test results would not change them, only prepare them for the future. The doctor swabbed the inside of Suzanne's cheek to obtain some cells. The DNA was extracted from these cells and tested for the gene. Suzanne's test came back positive-she had inherited the gene mutation APP from her father. When they got the news, Suzanne reacted with tearful stoicism, David with stunned silence. Suzanne and David now have a new dilemma. They have always wanted to have children, but understand that each of their children now has a 50% chance of inheriting the disease. In addition, it is likely that Suzanne will not be able to raise (or even recognize) her children as her disease progresses. This would have an impact on all of them-Suzanne, David, and any children they might have. Should they have children? Questions 1. What role is played by meiosis, oogenesis, and spermatogenesis in human reproduction? How is it possible that 50% of Suzanne's eggs will be carrying the mutated APP gene? 2. What is DNA? A gene? An allele? How do genes determine traits? 3. The APP gene codes for a particular protein. Why does a mutated APP gene lead to problems in the brain? What are the two other genes (and their resulting gene products-the proteins) that, when mutated, can lead to EOFAD? How does each protein play a role in brain function?
