Dr. Yoshitsugu Aoki is a physician-scientist at the forefront of RNA therapeutics and genetic medicine.As Director of the Department of Molecular Therapy at the National Center of Neurology and Psychiatry in Tokyo, Dr. Aoki has helped lead the development of antisense oligonucleotide (ASO) therapies for Duchenne muscular dystrophy—including viltolarsen, an exon-skipping therapy approved in both Japan and the United States.In this conversation, we explore how RNA therapies became a reality, what they’re doing for patients today, and where the field is heading next.⸻🔬 What we cover:

• What exon skipping is (in simple terms)
• How ASO therapies are helping Duchenne patients
• Breakthrough clinical results and what they mean
• Delivering therapies to the brain
• The future of RNA, gene therapy, and combination treatments
• How AI and robotics could accelerate drug development

Welcome — I’m Ron Kleiman, and this is GENEration Hope.In this episode, I’m joined by Dr. Guoping Feng, Professor of Neuroscience at MIT, affiliated with the McGovern Institute, the Yang Tan Collective, and the Broad Institute. We talk about: • Why he left medicine to pursue research that could lead to treatments for kids  • The urgency of moving faster — because “kids are growing up every day”  • Gene therapy delivery, the blood–brain barrier, and what’s changing with new vectors  • How AI and machine learning are speeding up vector design and behavioral testing  • The miniSHANK3 approach: why the full SHANK3 gene is too large, how a mini gene is designed, and how it’s delivered  • Where genome editing (base editing / prime editing) may fit in the future If conversations like this help, please subscribe, like, and share — it’s the best way to support GENEration Hope.

Sue Lomas helped build the Phelan-McDermid Syndrome community in the earliest days—when families were scattered, information was scarce, and finding “your people” took persistence. In this conversation, Sue and I talk about how rare-disease communities form, why early diagnosis and genetics matter, and how parent-led foundations can accelerate research by connecting families, clinicians, and scientists.We also explore the emotional side of the journey: the turning points that reshape what you believe is possible, the role of family support behind the scenes, and what purpose looks like after stepping away from a long mission.If you’re a rare disease parent, advocate, researcher, or someone who cares about the future of gene-based medicine—this one is for you.If this resonates, please like, subscribe, and share it with a family who needs hope today.Chapters 00:00 Cold Open: A moment that captures the mission01:33 Connecting with other foundations (learning by reaching out)03:42 Turning point: realizing more is possible (communication)06:40 The feeling of acceleration in research and progress09:53 The early days: “by luck” and finding the right people11:49 First conferences and building real community13:49 The support system: partnership and what it takes16:19 Early diagnosis & genetics (why it matters)19:09 Growing a foundation while staying cohesive22:03 “Shank3” in a classroom: when awareness spreads25:08 How this journey changes parents over time29:43 Advice for parents: planning, siblings, and support33:17 Retirement, purpose, and what comes next36:50 Final reflections and gratitude
