  1. Personal genetics: What it might it means for me, my family and society Personal Genetics Education Project (pgEd) Harvard Medical School www.pged.org National Science Teacher Association 2013 San Antonio, Texas

  7. pgEd’s goal: To encourage thoughtful discussion about personal genetics so people can make informed choices for themselves, their families, and society.

  8. Careers in science? Jim Henson, The Muppets

  9. Guiding questions in all our lessons: Why does it matter to you?How do we evaluate risk, and weigh the risks and benefits about DNA? Do genes always predict what traits and conditions we are going to have?

  10. Why is genetics getting more personal? • Knowledge about our DNA is becoming more detailed, inexpensive and widely accessible • Insights about our health, behavior, family history and traits grow on a daily basis • Highly personal information with social, legal and familial impact is available online and OTC personal genetics educationproject

  11. Why is talking with students so urgent? • “Under $1000 dollars in this decade” • “Widely available in the next 5-10 years” • “ Transforming health care for the next generation” • Average age to marry in the US, 2000-2003: Men 26.7, Women 25.1 • Average age of first-time mothers in the US, 2003: 25.2 • Sources: census.gov, cdc.org, NYT personal genetics educationproject

  15. Direct to consumer ( DTC) analysis for sale on the internet

  17. What information would you like to have about your risks for various diseases? Might your opinion change at different points in your life?

  18. Curiosity about ancestry, family history • Ideas for medical tests and interventions if I learn I’m at risk • To find the right drugs, in the right doses, for my conditions • Motivation to my change habits • Planning for my long term medical and financial needs • To inform my reproductive decisions personal genetics educationproject Why personal genome analysis?

  19. 1. How far ahead is the technology of its clinical usefulness? • 2. How much information would you want to know? • 3. Will fair weight be given to environmental & social factors? • 4. How will your genetic information affect your family?  • 5. How much should we be concerned about discrimination at work and by insurance companies?  • 6. How can we ensure access for all? personal genetics educationproject Personal genomes: what are the challenges?

  20. Genetic Information Non-discrimination Act (GINA) • “The first civil rights legislation of the 21st century” • -Senator Ted Kennedy personal genetics educationproject

  21. GINA: Prohibits discrimination in health insurance and employment Title 1: Prohibits discrimination in group and individual health insurance plans. Forbids genetic information being used to deny coverage, adjust premiums, or require someone to take a genetic test. Title 2: Prohibits employers from using genetic information to make hiring, firing or promotion decisions. Severely limits employers rights to request, require, or purchase an employee’s genetic information. personal genetics educationproject

  22. What are some of the big social issues in personal genetics? • Athletics and genetic testing – how much can DNA reveal about ourselves and our potential? • DNA and the law - Can we use DNA to keep us safe and preserve civil liberties at the same time? • How do we decide to use a new reproductive technology? pgEd lesson plans: All Common Core aligned, tackle these issues, active classroom, all free! WANT TO PILOT A LESSON?

  23. What might a “sports gene test” tell us? www.nytimes.com/2008/11/30/sports/30genetics.html personal genetics educationproject

  25. Connections between genetics and athletics? • There are genes involved with collagen production that are thought to be useful in predicting certain types of soft tissue injuries. • A small study indicates a possible link between having the ApoE4 variant and increased risk of severe effects from a concussion. • What is the predictive power of these •      variants? (genetics vs. environment) personal genetics educationproject

  26. ApoE4 and concussions: A new area of inquiry ApoE4 variant is also associated with Alzheimer’s disease (AD). People with one copy of the variant, ApoE4, have 3x higher risk for AD. People with two copies of the ApoE4 variant have 15X higher risk for AD. personal genetics educationproject

  27. ApoE4 and concussion risks? How does one weigh the benefits and risks of knowing about one’s genetic status related to AD? Would you want to test your child to help decide which sports to possibly avoid or to pursue? How much does the genetic component matter? Is this a family decision? Why or why not? personal genetics educationproject

  28. DNA and society: New ways to use DNA to solve crimes http://www.scientificamerican.com/article.cfm?id=portrait-in-dna personal genetics educationproject

  30. DNA as identification tool: beyond individual crimes personal genetics educationproject

  31. DNA collections used to prove innocence • The Innocence Project: Exonerated 274 people, 17 of these exonerations were death row inmates • 70% of exonerations have been people from minority groups personal genetics educationproject www.innocenceproject.org

  33. personal genetics educationproject PGD being performed on a 3-day old embryo Image via http://www.obgyn.net/Frontiers_In_Reproductive_Medicine/images/PGD.gif

  34. personal genetics educationproject • 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. What is preimplantation genetic diagnosis (PGD)?

  36. Men Women Public attitudes regarding PGD Transplants Adult illness Gender Strength & Intelligence Fatal Hudson 2006 Fertility & Sterility

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

  38. 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? personal genetics educationproject
