May 22#395 Mapping Melanoma: How Spatial Biology Is Advancing Cancer Research
What if we could study melanoma not just cell by cell, but in the exact place those cells live inside the tumor?
That is the promise of spatial biology. In this episode of DNA Today, we explore how emerging genomic technologies are transforming melanoma research by allowing scientists to examine not only which cells are present in a tumor, but where they are located, how they interact, and why those relationships matter.
May is Melanoma Awareness Month, making this an important time to spotlight how tools like spatial transcriptomics, single-cell sequencing, and multiomics approaches are helping researchers better understand tumor behavior, immune response, and treatment resistance.
Joining us are Professors Thomas Tüting and Andreas Braun, German dermatologists and researchers whose work focuses on melanoma, tumor immunology, and translational cancer research. We are also joined by Dr. Jia Hui Khoo, Product Manager at MGI, who brings expertise in spatial biology and the technologies helping make this research possible.
Together, we discuss an exciting melanoma research project profiling human melanoma samples from the University Hospital Magdeburg’s biobank, using MGI’s DCSP approach, which spans DNA, cell omics, spatial omics, and proteomics. This work has the potential to deepen our understanding of melanoma biology, tumor heterogeneity, immune landscapes, and the future of precision oncology.
In this Episode, We Discuss:
How melanoma research and treatment have evolved, especially with the rise of immunology and immunotherapy.
Why human melanoma biobanks are so valuable for translational cancer research.
How spatial biology helps researchers understand tumors in context, not just as isolated cells.
Why the location of cells within a tumor matters for understanding melanoma progression and immune response.
How spatial transcriptomics and single-cell sequencing can reveal differences between patients who respond well to immunotherapy and those who do not.
What researchers hope to learn by profiling STOmics spatial transcriptomics datasets alongside matched single-cell datasets from human melanoma and mouse models.
How MGI’s DNBSEQ and STOmics technologies support oncology research.
What MGI’s DCSP approach brings to melanoma research by integrating DNA, cell omics, spatial omics, and proteomics.
Why high-resolution spatial technologies like Stereo-seq may be especially important for studying the tumor microenvironment.
How multiomics research could eventually inform biomarker discovery, patient stratification, therapeutic development, and the future of human pathology.
Guests:
Professor Thomas Tüting, MD is Professor and Chairman of Dermatology at University Hospital Magdeburg in Germany, where his work focuses on tumor immunology, melanoma progression, metastasis, and resistance to cancer immunotherapy. He trained in dermatology at University Hospital Mainz and completed research training in experimental tumor immunology at the University of Pittsburgh. His research has explored how the immune system shapes melanoma biology, including the role of inflammation, tumor plasticity, and the tumor microenvironment in cancer progression and treatment response. In 2024, Professor Tüting was awarded an ERC Synergy Grant with collaborators at Uppsala University to advance immunotherapy research for malignant melanoma and brain tumors, with a focus on the vascular-immune interface and local anti-tumor immune activation.
Professor Andreas D. Braun, MD is a dermatologist and researcher in the Department of Dermatology, Allergology and Venereology at the University Hospital Schlewsig-Holstein in Lübeck. His research centers on melanoma biology, tumor progression, metastatic spread, and mechanisms that influence response or resistance to immunotherapy. Professor Braun has co-authored studies on topics including Hgf-Met and BRAF signaling in melanoma, tumor-intrinsic Toll-like receptor 4 signaling, MHC-I downregulation, CD8+ T-cell infiltration, and metastatic spread in melanoma. His work bridges clinical dermatology and translational cancer research, with a focus on using molecular and immunologic insights to better understand melanoma behavior and treatment response.
Dr. Jia Hui Khoo specializes in spatial biology and single-cell technologies. She leads the DCS portfolio at MGI EU&AF, advancing the adoption of spatial biology solutions. DCS represents MGI’s three core technology areas: DNA genomics, cell omics, and spatial omics. She began her work at MGI by leading collaborations using Stereo-seq with research institutions across Europe and now drives product strategy for the company’s spatial multi-omics portfolio.

May 15#394 How Newborn Sequencing Could Transform Pediatric Rare Disease Care in Florida
Newborn sequencing is no longer just a future-facing idea discussed in genetics circles. It is beginning to take shape through real pilot programs, state policy, and health system efforts exploring how genomics could fit into routine newborn care.
In this episode of DNA Today, we take a closer look at one example of that momentum: Florida’s Sunshine Genetics Act. The legislation created a five-year, voluntary newborn genetic sequencing pilot program and established the Sunshine Genetics Consortium. The program allows parents to opt in to newborn genetic screening, including whole genome sequencing. The state allocated millions for the Sunshine Genetics Pilot Program, along with additional funding for the Florida Institute for Pediatric Rare Diseases.
To unpack what this could mean for rare disease diagnosis, pediatric genomic medicine, and the future of newborn screening, our host Kira Dineen is joined by Dr. Pradeep Bhide, Director of the Florida Institute for Pediatric Rare Diseases, and State Representative Adam Anderson, who championed the legislation after losing his son Andrew to Tay-Sachs disease at age 4.
About Our Guests
Dr. Pradeep G. Bhide is the Jim and Betty Ann Rodgers Eminent Scholar Chair of Developmental Neuroscience, Director of the Florida Institute for Pediatric Rare Diseases, and Director of the Center for Brain Repair at the Florida State University College of Medicine. His work focuses on developmental neuroscience, pediatric rare disease research, precision diagnostics, and advancing treatments for children and families affected by rare genetic conditions.
Representative Adam Anderson represents District 57 in the Florida House of Representatives. He sponsored and championed the Sunshine Genetics Act, drawing from his family’s personal experience with rare disease after the loss of his son Andrew to Tay-Sachs disease. Through this legislation, Representative Anderson has helped position Florida as one of the first states to explore how genomic sequencing could be integrated into newborn screening and pediatric rare disease care.
In This Episode, We Discuss:
How Representative Anderson’s son Andrew inspired his advocacy for newborn sequencing and rare disease legislation
What the Sunshine Genetics Act makes possible for families in Florida
How newborn genome sequencing could shorten or prevent the rare disease diagnostic odyssey
The role of the Sunshine Genetics Consortium in coordinating researchers, clinicians, geneticists, children’s hospitals, and biotech innovators across the state
Why early genomic diagnosis can influence medical management, specialist referrals, surveillance, treatment planning, and access to clinical trials
How Florida’s approach fits into the broader global movement toward newborn sequencing, alongside programs such as Genomics England’s Generation Study, GUARDIAN in New York, BeginNGS at Rady Children’s, and NIH-funded BEACONS
What “whole genome sequencing” means in the context of this pilot, and how programs may distinguish between sequencing the whole genome and analyzing a targeted set of genes
How families may be educated about voluntary participation and informed consent
What types of results may be returned to parents and healthcare practitioners
How programs are thinking about childhood-onset, treatable, preventable, and potentially adult-onset findings
The connection between earlier diagnosis and emerging gene-based therapies
What it takes to move complex genomic medicine legislation forward
How Florida is building infrastructure for pediatric genomic medicine
Which outcomes will matter most as the five-year pilot unfolds, including enrollment, sequencing metrics, clinical impact, public health impact, cost effectiveness, and economic benefits, which are included in the reporting requirements for the program.
Why This Conversation Matters
For many families affected by rare disease, the search for a diagnosis can take years. Those years can include specialist visits, inconclusive testing, missed opportunities for early intervention, and emotional strain. Newborn sequencing raises the possibility of identifying certain serious genetic conditions before symptoms appear, allowing families and clinicians to act sooner.
At the same time, implementing newborn sequencing brings important questions: What conditions should be included? What results should be returned? How should parents be consented? How will privacy and data use be handled? What infrastructure is needed to support follow-up care? And how can programs ensure equitable access?

May 01#392 Your DNA Is Not Static: Roxanne Khamsi on Mutation & Mosaicism
What if one of the biggest assumptions in genetics is also one of the most incomplete? We often talk about DNA as though it is a stable blueprint, a fixed set of instructions inherited at conception and carried unchanged throughout life.
But in Beyond Inheritance, science journalist Roxanne Khamsi challenges that idea in a profound way, arguing that our genomes are far more dynamic, unstable, and biologically creative than most of us realize.
In this episode, Roxanne Khamsi dives into the science and implications of mutations that arise after conception, the spontaneous, somatic, and mosaic genetic changes that shape our tissues, immune systems, brains, aging process, and risk for disease.
We talk about how these changes complicate the idea of inherited disease, how cancer can be understood through evolution, why some mutations are harmful while others may actually rescue disease, and what all of this means for the future of medicine.
In This Episode, We Discuss:
Why DNA should not be viewed as static
What somatic mutations are and why they matter
The concept of mosaicism and what it means that every human is a mosaic
How Darwinian evolution can happen within the body
How mutation supports antibody diversity and immune defense
Clonal hematopoiesis and its links to cardiovascular disease and aging
Phenocopies and how spontaneous mutations can mimic inherited disease
Cases where cells appear to self-correct through additional mutations
Whether mutation accumulation may help drive aspects of aging

The Guest:
Roxanne Khamsi is an author, speaker, contributing writer for The Atlantic, and award-winning science journalist whose work has appeared in The New York Times, Nature, Scientific American, WIRED, and National Geographic. In Beyond Inheritance, she draws on more than two decades of reporting at the intersection of genetics and medicine to take readers through cancer biology, immune diversity, clonal hematopoiesis, somatic mosaicism, germline mutation, aging, and even microbial evolution, revealing mutation not as an occasional error, but as a constant force shaping life from within.

April 24#391 Living with FSGS: A Genetic Kidney Disease Journey
Kidney disease affects more than 1 in 7 adults in the United States, yet many people do not realize they are at risk until symptoms become serious. For some patients, kidney disease is tied to rare or genetic causes, making diagnosis and treatment even more complex.
In this episode of DNA Today, we explore focal segmental glomerulosclerosis (FSGS), APOL1-mediated kidney disease (AMKD), and the real-life impact of navigating a rare kidney disease diagnosis as a young adult.
Joining the show is Emani McConnell-Brent, who shares her personal experience living with FSGS, from early symptoms and delayed diagnosis to the emotional toll of learning her kidney disease is genetic.
Also featured is Dr. Pranav Garimella, Chief Medical Officer at the American Kidney Fund, who explains the science behind FSGS, when genetic testing for conditions such as AMKD should be considered, and why earlier recognition of kidney disease symptoms can make such a meaningful difference.
Together, they discuss the importance of listening to patients, not dismissing early warning signs like protein in the urine, and improving access to genetic evaluation for people with unexplained kidney disease or a family history of kidney problems.
Emani also opens up about how kidney disease changed her daily life, from monitoring her blood pressure and swelling to adjusting her plans, energy, and expectations as a young adult. Her story is a powerful reminder that earlier diagnosis does not just impact medical management, it can also shape a person’s mental health, future planning, and sense of control.
The episode also highlights the work of the American Kidney Fund, including its mission to support people living with kidney disease through education, advocacy, prevention, and resources for both patients and healthcare providers.
In This Episode, We Discuss:
What focal segmental glomerulosclerosis (FSGS) is
How FSGS affects kidney function
Emani McConnell-Brent’s journey to diagnosis
The role of APOL1 genetic risk variants in kidney disease
Why persistent protein in the urine should not be overlooked
When genetic testing may be appropriate in kidney disease evaluation
The mental health and lifestyle impact of chronic kidney disease in young adults
How the American Kidney Fund supports patients, families, and providers
About the Guests
Emani McConnell-Brent is a full-time student at Bowie State University majoring in psychology. She is an advocate for kidney health and mental health. Despite Emani’s diagnosis of focal segmental glomerulosclerosis (FSGS) in 2020, she has invariably displayed ambition, resilience and transparency. She refuses to allow her diagnosis or any lifelong outcomes to dictate her success. Instead, she views her diagnosis as an opportunity for advocacy and education. Emani has since devoted her platform to telling her story and to bringing awareness to APOL1-mediated kidney disease and health disparities among African Americans.

Dr. Pranav Garimella, MBBS, MPH, FASN, joined the American Kidney Fund as its first Chief Medical Officer in January 2025. A board-certified nephrologist and nationally recognized leader in rare kidney diseases, he also serves at UC San Diego Health as Director of Acute Dialysis Services and the Polycystic Kidney Disease Center of Excellence. Dr. Garimella is an accomplished researcher focused on kidney function, cardiovascular disease, bone health, and mortality, with NIH-funded work and more than 110 peer-reviewed publications. He is also a trained epidemiologist, frequent journal reviewer, and fellow of the American Society of Nephrology.

April 17#390 Prince, Mayte Garcia, and Their Son Amiir’s Pfeiffer Syndrome Type 2 Story
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. A professional belly dancer since age three, she became internationally known as Prince’s muse, collaborator, featured dancer for the New Power Generation, and later his first wife.

April 10#389 From Natural History to Gene Therapy: The Future of Danon Disease Research
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 UC San Diego.
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.

April 03#388 From Medical Mystery to Gene Therapy: One Family’s Sialidosis Journey
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.

March 27#387 The Hidden Work of Rare Disease: Navigating a Broken Healthcare System
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.

March 20#386 Achondroplasia Beyond Height: Managing Lifelong Medical Needs
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.
