Critically Speaking

Oct 16, 2019

In this episode, Therese Markow and Dr. Ricki Lewis discuss the change in consumer genetic testing that became possible due to the human genome project. Dr. Lewis has utilized the genetic testing more than once herself and they discuss how the results of the test varied, as well as the surprise and irony of the geneticist receiving surprise genetic test findings. Dr. Lewis has had a long career in the life sciences, including her authorship in 36 textbooks and her publications in multiple journals and magazines.  


Key Takeaways:  

  • In 6 months, 23andMe was able to find a Parkinson’s Disease chain using 10,000+ people’s voluntary results of the testing. 
  • As soon as you find out you have half siblings, half of your medical history is incorrect. 
  • Learning information from older relatives can help you put pieces together with your genetic history. 


"Think really carefully before you start delving into your genetic information." —  Dr. Ricki Lewis
