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

Welcome to GENEration Hope — I’m Ron Kleiman.Today’s guest is Dr. Katy Phelan, a pioneering human geneticist and one of the founders of the Phelan-McDermid Syndrome Foundation (PMSF). This conversation was recorded at the PMSF Annual Conference (2024).Dr. Phelan takes us back to the earliest days of how Phelan-McDermid syndrome was first identified, how families found each other long before social media, and why community became a turning point for so many parents.We also break down diagnostics in plain language — including microarray, sequencing, and why chromosome analysis can still matter — and we talk about what’s giving families real hope as research and treatments move closer.If conversations like this are helpful, please subscribe and turn on notifications so you’re alerted each month when a new interview drops, along with updates from GENEration Hope.Stay Hopeful,Ron⸻Chapters (paste into YouTube)00:01:21 Who is Dr. Katy Phelan (geneticist + PMSF founder)00:01:44 “Girls aren’t built for math” — and proving that wrong00:03:17 Why human genetics (and the Celtics + PMS colors story)00:04:39 The first 22q13 deletion case and the start of collaboration00:06:04 Community and siblings00:07:41 How close are we to treatments?

Dr. Curtis Rogers is a Senior Clinical Geneticist at the Greenwood Genetic Center and a long-time leader in the Phelan-McDermid syndrome (PMS) community.In this wide-ranging conversation recorded at the 2024 Phelan-McDermid community conference, we talk about: • What inspired Dr. Rogers to pursue medicine and genetics • How Phelan-McDermid syndrome was first recognized • How families built a community even before the internet • How genetic testing evolved from early chromosome studies to today’s sequencing • Why access, wait times, and insurance can slow diagnosis • The promise—and ethical complexity—of newborn screening • Where AI is beginning to help in clinical genetics • Why delivering genetic medicines to the brain is one of the biggest real-world challengesGENEration Hope shares stories and science from the rare disease community—focused on what’s changing now, and what’s coming next.▶️ Subscribe for more interviews: @GENErationHope_1 🌐 Learn more: generationhope.co#PhelanMcDermid #SHANK3 #RareDisease #Genetics #GeneTherapy

Newborn genome sequencing isn’t science fiction anymore. It’s already changing which babies get diagnosed, when they get treated, and how many families spend years in diagnostic limbo.When our daughter Evie started missing her milestones, we spent five years bouncing between specialists, MRIs, EEGs, blood tests, microarrays and more—with no answers. It took whole exome sequencing to finally reveal a point mutation in SHANK3, now known as Phelan-McDermid syndrome. Our story is heartbreakingly common for families with genetic disorders—and the emotional and economic cost is huge. In this episode of GENEration Hope, I sit down with Dr. Wendy K. Chung—clinical and molecular geneticist, Chair of Pediatrics at Boston Children’s Hospital and Harvard Medical School, and Principal Investigator of the GUARDIAN newborn genome screening study. We talk about: • How whole-genome sequencing (gWGS) is changing newborn diagnosis • What the GUARDIAN study is finding in over 13,000 babies so far • Why Rett syndrome is far more common than we thought (around 1 in 1,500 girls) • The week she diagnosed a 72-year-old and a 3-week-old with Rett • The ethics of telling parents about serious conditions when babies still look “perfectly fine” • How families can “stand up and be counted” in registries so they’re not left out of future trials • Why early diagnosis is essential for gene-targeted therapies—and why timing may one day mean treating even before birth
