This is our sixth installment in our Mock Genetic Counseling Session Series! In this episode, genetic counselor Charlotte Close and student Marcely Ventura perform a mock genetic counseling session. The session indication is an abnormal newborn screening result for cystic fibrosis.    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.
