2 Discussion Questions: If you could choose specific traits or qualities that you would want your child to have, what would you choose? Why? Are there any you would not want your child to have? What are they? Why?

3 personal genetics education project What is preimplantation genetic diagnosis (PGD)? What is preimplantation genetic diagnosis (PGD)? PGD is a method to test for certain genetic traits in an embryo, almost always for genetic disease. An embryo is created via in vitro fertilization. Genetic testing occurs when embryo is 2-4 days old, typically at the 8-cell stage. A single cell is removed and tested. The results of testing are used to decide which embryos, if any, to implant in prospective mother’s uterus.

6 personal genetics education project What % of IVF clinics provide testing for the following reasons? aneuploidy autosomal disorders chromosomal rearrangement X-linked diseases non-medical sex selection avoid adult-onset disease HLA typing HLA typing w/o single gene test Select for a disability

7 personal genetics education project Public attitudes regarding acceptable uses of PGD: fatalHLA matchadult onset disease sexIntelligence/ strength

8 Wants a total ban on PGD Supports government regulation of safety and quality Thinks government should regulate ethics only Supports no government regulation Believes government should regulate safety, quality and ethics Opinion poll: What role, if any, should the US government play in regulating preimplantation genetic diagnosis (PGD)?

9 personal genetics education project Discussion Questions What are the potential opportunities and challenges of PGD? Now that we’ve discussed the issue a bit, did you change your opinion about whether you’d want to choose certain traits for your child? If your parents used this on you - should they tell you? Or is it no big deal? Do we need rules to guide how this is used? If yes, what sort of rules? Whose job would it be to enforce them?
