Textbook Question
Chapter 16, Problem 17QP
You are a genetic counselor, and your patient has asked to be tested to determine if she carries a gene that predisposes her to early-onset cancer. If your patient has this gene, there is a 50/50 chance that all of her siblings inherited the gene as well; there is also a 50/50 chance that it will be passed on to their offspring. Your patient is concerned about confidentiality and does not want anyone in her family to know she is being tested, including her identical twin sister. Your patient is tested and found to carry a mutant allele that gives her an 85% lifetime risk of developing breast cancer and a 60% lifetime risk of developing ovarian cancer. At the result-disclosure session, she once again reiterates that she does not want anyone in her family to know her test results.
- a. Knowing that a familial mutation is occurring in this family, what would be your next course of action in this case?
- b. Is it your duty to contact members of this family despite the request of your patient? Where do your obligations lie: with your patient or with the patient’s family? Would it be inappropriate to try to persuade the patient to share her results with her family members?

A 45-year-old woman undergoes genetic testing and discovers that she is at high risk for developing colon cancer and Alzheimer disease. Because her children have 50% of her genes, they may also be at an increased risk for these diseases. Does she have a moral or legal obligation to tell her children and other close relatives about the results of her genetic testing?
As a genetic counselor, you inform Susan and John that a blood test for cystic fibrosis is available. would you recommend generic testing for Susan and John?
Explain whether the woman having genes for high risk for developing cancer and Alzheimer disease is morally or legally obligated to tell her children and close relatives about the genetic testing.

- In Section 12-1, Julie is concerned that she may develop breast cancer, but testing shows that she does not carry the rare high-risk BRCA1 and BRCA2 alleles. What if further testing showed that some of her aunts, her mother, and she carried a common low-risk allele for breast cancer. What would you recommend to Julie if you were her genetic counselor?arrow_forwardA couple has had a child born with neurofibromatosis. They come to your genetic counseling office for help.

Ignoring ethical and privacy concerns, Jeremy decides that since he has just learned about PCR in class, he will perform a paternity test on the side during his BISC 336 lab to determine whether Mike is related to the mailman or whether he is related to the Corner store clerk.

- The DNA profile of each individual is highly specific. The chances of two people having exactly the same DNA profile is 30,000 million to 1 (except for identical twins). Given a set of DNA profiles in figure 3, determine who the father is in a paternity case. The Case: Missis De Los Santos has a daughter who is in need of a liver transplant. Unfortunately, Mrs. De Los Santos was ruled out as a donor. She was asked to ask if her daughter's father could also go for a check-up for donor compatibility. Mrs. De Los Santos believes one of two men is her daughter's father. Who between the men is the daughter's father? Determine who the father in the case is by comparing the DNA profiles of the persons involved in the case. At the end of your profiling activity, you will know that you have correctly figured out who the father is if you have accounted where all the DNA markers of the daughter came from.
