It's 7q11.23 Day! Jen and Brendan are joined by Kieran Devin Johnson, a young man from the Denver area who loves both paintball and  @Southwest  Airlines! Seriously,  @Southwest  , you must give this guy a listen! The Geneticist and WS Mom Jocelyn Krebs teaches Jen and Brendan about the importance of 7q11.23, what it means, and her wonderful artwork to help us celebrate this once-a-century event!
