  • This is our third installment in our new Mock Genetic Counseling Session Series! In this episode, pediatric genetic counselor Miranda Di Biase and students Claire Zimlinghaus and Joy Lin perform a mock pediatric genetic counseling session. This session’s indication is one of the most common in pediatric genetics: autism. This session was recorded in person, providing a more dynamic and engaging learning experience therefore, we highly recommend watching it on YouTube to fully immerse yourself in the interaction. We hope this series is helpful for prospective and current genetic counseling students, as well as the general public, by demystifying the genetic counseling process. Understanding how these sessions work can empower individuals and provide valuable educational insights into this critical healthcare service.
