As a multistakeholder group of authors, we are a diverse group with expert perspectives on the social, emotional, physical, and logistical burdens/benefits of trial participation and the myriad ways they affect pediatric GT research. For both pragmatic and ethical reasons, it is essential to prioritize addressing child participant and adult caregiver needs and concerns when designing and conducting GT clinical trials in pediatric populations with rare genetic neurological disorders. We use the term “lived experience” in reference to how people think about and make decisions regarding participation in research studies and how they articulate the emotional, social, ethical, and equity tradeoffs that impact their lives and illness experience.
