DNA Today: A Genetics Podcast

In this special episode of DNA Today, Kira Dineen sits down with Mayte Garcia — artist, author, internationally acclaimed dancer, actress, singer, choreographer, philanthropist, and the former wife of Prince — for a deeply personal conversation about love, loss, legacy, and the rare genetic condition Pfeiffer syndrome type 2. You may know Prince as one of the most influential musicians of all time, but in this episode, we step beyond the public image and into a far more intimate story: Prince and Mayte as expectant parents, the profound love they shared for their son Amiir, and the devastating medical journey that followed after his birth. Mayte reflects on pregnancy, the bond she and Prince formed with Amiir before he was born, the difficult decisions they faced, and what it meant to navigate a rare diagnosis in the 1990s before information was as accessible as it is today.  Kira also provides helpful context on Pfeiffer syndrome, including its genetics, symptoms, and why Amiir’s diagnosis of the severe type 2 form carried such serious medical challenges. This conversation also explores grief — both private and public — as Mayte shares what it was like to mourn Amiir while under the intense pressure of public life. She offers moving insight for parents who feel pressure to hide their pain, and reflects on how writing her memoir, The Most Beautiful: My Life with Prince, became part of her healing. The episode closes on legacy: not only Prince’s legacy as a global music icon, but his humanitarian spirit and the work that continues through Live 4 Love Charities, the nonprofit founded in memory of Amiir and rooted in Prince’s philanthropic vision. This month marks 10 years since Prince passed away, and also 30 years since their son Amiir died. Mayte is honoring them both through a special Live 4 Love Charities Glam Slam Benefit in Los Angeles on April 21st, 2026. We Discuss: Prince and Mayte’s bond with Amiir during pregnancy Why they declined amniocentesis during the pregnancy What Pfeiffer syndrome type 2 is and how it differs from other forms The genetics of Pfeiffer syndrome, including FGFR2 and de novo variants The medical complexity of Amiir’s care after birth Prince as a father behind the public persona Grief, public image, and the pressure to “perform” wellness Mayte’s memoir and why she chose to tell this story The legacy of Amiir Prince’s humanitarian legacy beyond music Mayte’s leadership of Live 4 Love Charities The upcoming Glam Slam Benefit on April 21st honoring Prince’s life and impact About Mayte Garcia Mayte Garcia is a Puerto Rican dancer, choreographer, actress, singer, author, and philanthropist.

Danon disease is a rare, X-linked metabolic disorder that strikes at the heart of cellular function. Caused by mutations in the LAMP2 gene, it disrupts the body’s ability to clear cellular waste (autophagy), leading to devastating and often life-threatening cardiac complications. Because the disease is so rare, understanding its natural progression, and how to stop it, is the current "North Star" for researchers and clinicians alike. In this episode, we are joined by two world-renowned experts to discuss the current landscape of Danon disease research: Dr. Barry Greenberg and Dr. Cordula Wolf. We dive deep into the mechanics of the disease, the importance of the LAMPLIGHT-NH observational study, and the groundbreaking LAMPLIGHT-2 interventional gene therapy trial. Meet the Experts Dr. Barry Greenberg (US): A pioneer in heart failure research and Director of the Advanced Heart Failure Program at UCSD. Dr. Cordula Wolf (Germany): A leading expert in pediatric cardiology and congenital heart defects, specializing in the clinical management of metabolic cardiomyopathies. Understanding the Disease Course Danon disease is fundamentally a "traffic jam" at the cellular level. Without a functional LAMP2 gene, lysosomes cannot fuse with autophagosomes, leading to a buildup of cellular debris. The Impact: This manifests primarily as hypertrophic cardiomyopathy, skeletal muscle weakness, and intellectual disability. The Cardiac Threat: For many patients, especially males, the disease progresses rapidly toward end-stage heart failure or sudden cardiac death, often requiring heart transplants at a young age. Resources & Clinical Trial Links If you are treating a patient with a confirmed or suspected LAMP2 pathogenic variant, your referral to a study site can change the trajectory of their care. Observational (LAMPLIGHT-NH) Best for gathering data without changing current management. Natural History Study (LAMPLIGHT-NH): ClinicalTrials.gov NCT06214507 Interventional (LAMPLIGHT-2) A Phase 2 trial for those meeting specific cardiac and age requirements.

What happens when a rare, devastating genetic condition impacts not just one person in a family, but three siblings? In this episode of DNA Today, we’re joined by siblings Faith Sinclair and Dan Peach who both have sialidosis.  Sialidosis is a rare lysosomal storage disorder that often leaves families searching for answers for years. Faith and Dan share their deeply personal journey with the condition, from the initial struggles of seeking a diagnosis for their brother, Antonn, to the cutting-edge gene therapy research currently underway.   Inside This Episode: The Diagnostic Odyssey Faith and Dan share the emotional impact of living with Sialidosis and the long road to a definitive diagnosis. We explore the uncertainty that many rare disease families face and how receiving an answer after years of "red flags" reshaped their lives. Understanding Sialidosis (The Science) We break down the clinical and cellular mechanics of Sialidosis. We discuss: The role of the NEU1 gene and how mutations lead to cellular dysfunction. The two primary forms of the condition (Type I and Type II) and their clinical presentations. Why Sialidosis is frequently misdiagnosed or overlooked by clinicians. Daily Life & Advocacy What does it look like to manage a rare condition day-to-day? Faith offers a candid look at the balance between medical management and the psychosocial burden on patients and siblings. Dan discusses how his personal and familial connection fueled the mission of Cure Sialidosis. The Future of Treatment: Gene Therapy We look toward the horizon of rare disease research. Sialidosis is currently entering the pre-clinical gene therapy stage, where the goal is to correct the NEU1 gene. Dan provides an update on the status of enzyme replacement and the global drive to raise funds for manufacturing the treatments required for human trials scheduled for 2026.   About Our Guests: Dan Peach is a founding member of Cure Sialidosis and a board member of Cure Mucolipidosis. As one of five siblings, three of whom were affected by Sialidosis, his connection to the disorder is profound. Since helping facilitate the diagnosis of his brother Antonn and sister Faith, Dan has become a dedicated patient-researcher. He leads a global community of patients, clinicians, and researchers, collaborating worldwide to address the root causes of the disease and improve outcomes for all affected. Faith Sinclair is a patient advocate living with Sialidosis, and sister to Dan. Her journey from years of medical uncertainty to a definitive diagnosis has made her a vital voice in the rare disease space, dedicated to sharing the unique perspectives of patients and their families.     Relevant Resources:  CureSialidosis.org Kiwi siblings battling rare genetic condition Sialidosis therapy: Kiwi siblings fundraise for injection against disease that killed brother - NZ Herald    More Lysosomal Storage Disorder Episodes on DNA Today: #380 “Rare Rebels”: When Parents Drive Science, The Story of MPS I #376 Why Females with Fabry Disease Aren’t “Just Carriers”  #372 Fighting for Time: Hunter Syndrome (MPS Type II), Gene Therapy & Urgent Advocacy #292 TALEN® Gene Editing Technology with Cellectis (MPS type I Research) #281 Tay-Sachs with Dr. Matthew Goldstein #171 Farber Disease with Aceragen    Connect With Us:  Get ready, genetic nerds, another brand-new episode of DNA Today drops this Friday!

In this special live recording from The University of Connecticut’s 2026 Rare Disease Symposium, host Kira Dineen, moderates a powerful panel featuring individuals living with rare conditions. The conversation moves beyond clinical diagnostics to explore the "hidden work" of navigating the healthcare system, the trauma of medical dismissal, and the fierce advocacy required to survive and thrive in a complex medical landscape. Shoutout to the lead organizer Anthony Zuo for putting this conference together.    The Panel (in order of appearance)    David (Dave) Leeds: Lives with Hereditary Angioedema (HAE) with normal C1 inhibitor (specifically the HS3ST6 gene mutation), a type of HAE that affects fewer than 20 people worldwide. He also advocates for his son, who has Specific Antibody Deficiency.   Kate Tokarski: A social worker and former paramedic living with three conditions: vitiligo, type 1 diabetes, and SUNCT syndrome (short-acting unilateral neuralgiform headache with conjunctival injection and tearing). She navigates a "rare family" dynamic, including children affected by gastroparesis, keratoconus, juvenile arthritis, celiac disease, ampfield pain syndrome, COPA syndrome, and median arcuate ligament syndrome.    Jill Gassman Zullo: Lives with Sinus Nasal Mucosal Melanoma, a rare cancer affecting less than 1% of the population. She is the author of Brokenly Beautiful.    Jonathan Cappiello: After 20 years of having a misdiagnosis, he was correctly identified as having a nano-rare disease, 3-hydroxy-3-methylglutaryl-CoA synthase deficiency. He is also the host of 1 of 20 podcast.   Topics Discussed  The Burden of Expertise A recurring theme is the "expert patient." Panelists describe the exhaustion of knowing more about their conditions than the providers treating them. Kira emphasizes the importance of medical professionals being comfortable saying, "I don't know," rather than muddling through an answer. Navigating the Emergency Room David describes the danger of ER protocols. For HAE patients, standard allergy treatments like EpiPens and steroids do nothing for their Bradykinin-based swelling, which can be fatal if it affects the throat. The panel discusses "Medical PTSD" and why the ER is often a place of last resort. The Battle with Insurance and Systems Kate shares a heartbreaking story of "Systemic Trauma": The Insurance Loop: Her daughter was denied a life-changing medication due to a bureaucratic glitch. The School-to-Court Pipeline: Because she missed school due to her autoimmune crises, Kate was reported for neglect, and her 16-year-old was read her Miranda Rights in family court for being a "truancy outlier." The Power of Community and Storytelling Jonathan discusses his journey as a science podcaster, using his background in film and journalism to give a platform to others with rare diagnoses. The panel highlights how storytelling is a form of survival and a tool for systemic change.   Relevant Resources:  Jill Gassman Zullo’s book Brokenly Beautiful Jonathan Cappiello’s podcast 1 of 20 podcast Kate Tokarski’s poem I Was 'That Mom'  National Organization for Rare Disorders (NORD) Undiagnosed Disease Network (UDN) Genetic and Rare Diseases Information Center (GARD)   Relevant Rare Disease Patient Advocacy Stories on DNA Today: #380 “Rare Rebels”: When Parents Drive Science, The Story of MPS I #371 Growing Old Too Fast: A Mother’s Fight for Cockayne Syndrome Advocacy #372 Fighting for Time: Hunter Syndrome, Gene Therapy & Urgent Advocacy #356 From Statehouse to Capitol Hill: A Guide to Effective Advocacy for Rare Diseases #342 $10 Million for a Cure: Donating Mr. Beast’s “Beast Games” Winnings For Son’s Creatine Transporter Deficiency Connect With Us:   Luckily you don’t have to wait long for a brand-new episode of DNA Today, we drop episodes every Friday!

What does it mean to truly care for a child with achondroplasia beyond just their growth differences? Achondroplasia is the most common form of skeletal dysplasia, but it is so much more than height. Children and adults with achondroplasia can have medical complications that require lifelong monitoring and the need for lifelong multidisciplinary care. This is the second episode in our three-part series on achondroplasia, sponsored by BioMarin. In our first episode, (Episode 359 of DNA Today) Dr. Janet Legare helped us explore the basics of achondroplasia and the role of genetics in diagnosis and family counseling. In this conversation, we’re shifting the focus to what living with achondroplasia actually looks like day to day, from managing medical complications to coordinating care across multiple specialties. Joining us is Dr. Ricki Carroll, a complex care and palliative care physician on the multidisciplinary skeletal dysplasia team in Delaware. Dr. Carroll brings expertise in providing a medical home for children with skeletal dysplasias, with a special focus on pain and symptom management. She also co-leads a skeletal dysplasia consultative service, and her training in bioethics adds a unique perspective on delivering compassionate, individualized care. In This Episode, We Discuss Building a Medical Home What a “medical home” means for children with achondroplasia Common concerns families raise after a new diagnosis, beyond height Supporting families early while planning for long-term care Co-Morbidities & Clinical Complications Key conditions clinicians should monitor in infants and children, including: Foramen magnum stenosis Hydrocephalus Sleep apnea ENT issues like recurrent ear infections and hearing loss Orthopedic challenges such as kyphosis, spinal stenosis, and bowed legs How chronic pain presents and is managed across childhood and adulthood Living With Achondroplasia How medical needs evolve from childhood into adolescence and adulthood The role of fatigue, mobility limitations, and accessibility in daily life Balancing medical care with childhood independence and normalcy Under-recognized burdens that significantly affect patients and families Multidisciplinary Care in Practice What a full skeletal dysplasia care team looks like How palliative care supports symptom management, decision-making, and quality of life Coordinating care across specialties like orthopedics, neurosurgery, ENT, and audiology Preventing communication breakdowns between providers Helping families navigate complex choices around interventions and surgeries Looking Ahead Gaps in current care models for achondroplasia How emerging treatments are changing long-term planning conversations Key takeaways for providers who may only occasionally care for patients with achondroplasia   Our Guest Dr. Ricki Carroll: Dr. Ricki Carroll is a complex care and palliative care physician on the skeletal dysplasia and palliative care teams at a hospital in Delaware. Dr. Carroll works to provide a medical home and manage care for children with a wide array of skeletal dysplasias. Her background in palliative medicine allows her to focus on pain and symptom management needs for these children, teens and young adults. Dr. Carroll also leads the skeletal dysplasia consultative service, providing care for infants and children with skeletal dysplasias who are in the hospital. Additionally, drawing upon her Master’s in Bioethics, she is currently serving as co-Chair of an Ethics and Patients’ Rights Committee.   Achondroplasia Resources:  Little People of America (LPA)  Dwarf Athletic Association of America (DAAA)  International Achondroplasia Forum  Achondroplasia GeneReviews  Achondroplasia Growth Charts Ireland PJ, Johnson S, Donaghey S, Johnston L, McGill J, Zankl A, Ware RS, Pacey V, Ault J, Savarirayan R, Sillence D, Thompson E, Townshend S.
