  1. Ethical issues in genetics and genomicsSection 3 Lesson Plan: Ethical issues in genetics and genomics – considering how people make decisions

  2. This powerpoint has a series of ethical scenarios, you can mix and match which ones you would wish to include There is also a word document which has a set of consent and confidentiality scenarios available with kind permission from the Joint Committee on Medical Genetics

  3. Ethical issues – case 1 David (19) collapsed and was found to have a HB of 6.4g/dl. Investigations identified Familial Adenomatous Polyposis (an inherited cancer syndrome with mean age of death 40). His sister and a maternal aunt were also at risk. David was willing to discuss his diagnosis with his sister but refused to contact his maternal aunt because of a serious family rift.

  4. Ethical issues – case 1 • What ethical issues does this raise? • How might the professionals involved endeavour to resolve the situation? • The maternal aunt is also a patient of the general practitioner involved. Does this raise any other ethical issues?

  5. Ethical issues – case 2 Judith (26) comes from a family with a significant history of ovarian cancer. A causative mutation has been identified in a maternal aunt. Judith is at 25% risk of having inherited the altered gene and requests a predictive test. Her mother (at 50% risk) has previously stated that she does not wish to know her gene status. If Judith has a positive result, her mother’s status will inevitably be revealed.

  6. Ethical issues – case 2 • Consider the ethical issues raised from both Julie and her mother’s perspective. • How might the professionals involved attempt to resolve this situation? • What clinical considerations might influence the decisions made?

  7. Ethical issues – case 3 Amy developed breast cancer several years ago at the age of 37. She has since been found to have a BRCA1 mutation (one of the gene mutations which are known to predispose to breast cancer). She would like her two daughters, aged 15 and 9, to have a predictive test.

  8. Ethical issues – case 3 • What ethical issues are raised by this request? • Would predictive testing be appropriate or not? Whatever your conclusion please try to identify several reasons.

  9. This next set of slides include more family history to enable the ‘students’ to consider the wider implications for the family
