Review the following key ethics terms:
Read Genetic Screening by Burke, et al. Focus on the content found on pages 154- 156.
Then watch Nathan’s Story: Tay-Sachs Disease in the Irish Population followed by Dr. Fullerton’s introductory video.
Dr. Fullerton introduces the following case:
“A young couple who are interested in starting a family come to you to discuss undergoing genetic carrier testing prior to trying to conceive. Both members of the couple are healthy and there is no known history of genetic disease in either patient’s background. However, the husband does have a younger brother affected by Down Syndrome who lives semi- independently in a group home. They each self-identify as being of Caucasian (not Irish or French Canadian) ethnicity and report no known Ashkenazi or Jewish Ancestry.”
“They are now aware of a wide range of recessive genetic conditions for which they could be tested. They simply want to avoid having a child with a truly devastating prognosis such as Tay-Sachs disease. Therefore, they request a test of the HEXA gene only.”
Review: the 4-Box Method…
Consider (A): how does the 4-Box method apply to Dr. Fullerton’s case using this 4-Box worksheet for guidance.
Consider (B): how might the following ethics concepts help you to (1) categorize the ethical issue(s) and (2) justify your response to the family:
Should you honor this request or recommend that the couple consider carrier testing for additional genetic conditions instead?
- CONSEQUENCES: What are the harms and benefits?
- RULES: What are the norms, laws, standards of practice, legal and ethical rights, obligations and responsibilities?
- VIRTUES: What might it mean to manifest sympathy, empathy, courageousness, trustworthiness, openness, respectfulness, or other virtues in this case?
- SOCIAL RELATIONS: Consider the interpersonal relations, social norms, and power structures.

For more information about genetic testing we would refer you to “Carrier testing for Ashkenazi Jewish disorders in the prenatal setting” by Ferriera et al. This article was published in the American Journal of Obstetrics and Gynecology. It is above the level of the average foundations phase student.
