Borrowing a case study here used at a national meeting of nurse practitioners:
As genomic information becomes a part of common medical disorders, the primary care practitioner will have to assume responsibility for providing patients and families with an understanding of the risks and benefits of genetic knowledge.
So consider this case: Mr. and Mrs. G are a couple who are being referred for prenatal genetic evaluation in their current (4th) pregnancy. Mrs. G is 34 years old and currently is 9 weeks pregnant.
They have two sons, ages 12 and 10, who are healthy. Their 8 year old daughter, Annie, has a diagnosis of congenital adrenal hyperplasia (CAH). Annie has the classic salt wasting form of this disorder and is being followed by the pediatric endocrinologist at the local children’s hospital.
The gene for this particular condition is known and the parents were counseled that testing the current pregnancy could be done if the mutations in the family were identified. This information could then be used to test the fetus and determine if prenatal treatment of an affected female fetus is indicated.
Blood from Annie and her parents was drawn for direct DNA testing. The parents were informed it would take about 2 weeks for the DNA lab to complete this testing. Two weeks later, the laboratory director gives you a call. She says that DNA analysis identified both mutation in Annie, and that Mrs. G was found to be a carrier for one of these mutations.
However, no mutation was found in Mr. G, which means he could not be Annie’s biological father.
ETHICAL ISSUE: Should the primary care practitioner inform the mother/father or both of non-paternity?
Don’t skip “the answer” and then sit back looking smug. Trace your moral spontaneous judgments before we do any ethics at all. My hunch is that these will be broad-ranging—and thus there will be “meat” for several “ethical analyses.”
Want to tell us what your spontaneous moral judgments are??????? And where they lead??????
