    #409 How DNA Testing Exposed the Dark History of American Adoption

    What happens when stigma, secrecy, and institutional power separate a mother from her child, and prevent an adoptee from accessing his own identity and medical history for decades? This week, we are sharing an episode of DNA Clarity and Support, the newest podcast to join the Gene Pool Media network. Host and genetic counselor Brianne Kirkpatrick Williams speaks with New York Times bestselling author and journalist Gabrielle Glaser about her book, American Baby: A Mother, a Child, and the Shadow History of Adoption. American Baby follows Margaret Erle Katz, who became pregnant as a teenager in 1961, and the son she was pressured to relinquish for adoption. That child, later named David Rosenberg, grew up without access to his biological family or family medical history. Decades later, while experiencing serious health problems, David used direct-to-consumer DNA testing to identify his birth family and discovered that the story he had believed about his adoption was not true. Through David and Margaret’s experiences, Gabrielle exposes the coercion, secrecy, and stigma that shaped the postwar adoption industry, and explores why access to original birth records, genetic relatives, and family health history remains so important. On This Episode, We Discuss: How Gabrielle met David while reporting on his kidney transplant How DNA testing connected David with his biological family What David discovered about his birth parents’ efforts to keep him How sealed adoption records restrict access to identity and family medical history Stigma, coercion, and secrecy in postwar American adoption Unethical research conducted on infants awaiting adoption The emotional complexity of unexpected biological connections and family reunions Privacy concerns surrounding commercial DNA databases Support resources for adoptees and others navigating DNA discoveries Margaret’s journey from decades of secrecy to adoptee-rights advocacy About Gabrielle Glaser Gabrielle Glaser is a New York Times bestselling author and journalist whose work on mental health, medicine, addiction, and culture has appeared in The New York Times Magazine, The New York Times, and many other publications. Her fourth book, American Baby: A Mother, a Child, and the Shadow History of Adoption, examines the history of adoption in post–World War II America through the story of one family separated by the country’s secretive and coercive adoption system.

    #408 Low ALP, Fractures, and Early Tooth Loss Point to Hypophosphatasia

    Hypophosphatasia (HPP) can present very differently from one person to the next, from life-threatening complications in infancy to fractures, chronic pain, muscle weakness, or early tooth loss later in life. With symptoms spanning multiple body systems and varying across the lifespan, how can clinicians recognize when these seemingly disconnected findings may point to HPP? In the first episode of our three-part series on hypophosphatasia, we are joined by genetic counselor Amy Patterson to explore the clinical spectrum and diagnosis of HPP. Amy explains what happens biologically in HPP, why traditional age-based classifications do not always capture its variability, and how the condition may present from the prenatal period through adulthood. We also discuss the importance of persistently low alkaline phosphatase (ALP), including why results must be interpreted using age- and sex-appropriate reference ranges. Amy reviews the additional laboratory findings, medical and dental histories, imaging, physical examination, and molecular testing that may contribute to a diagnosis. She also highlights common misdiagnoses and the clinical clues that should prompt healthcare providers to consider HPP. Episode Discussion Topics What hypophosphatasia is and how impaired mineralization affects the body The perinatal, infantile, childhood, adult, and odonto forms of HPP Prenatal and infantile presentations of severe HPP Clinical and dental signs in children Fractures, chronic pain, fatigue, weakness, and dental concerns in adults How manifestations may change throughout a person’s lifetime Variability among relatives with the same familial ALPL variants Common diagnostic delays and misdiagnoses Distinguishing HPP from other causes of rickets and skeletal abnormalities Differentiating HPP from osteoporosis, osteopenia, osteoarthritis, and fibromyalgia The importance of persistently low ALP and appropriate reference ranges Alternative explanations for a low ALP result The HPP International Working Group The roles of laboratory testing, radiographs, dental records, and medical history When molecular testing of the ALPL gene may be appropriate Whether HPP can be diagnosed without an identified pathogenic or likely pathogenic ALPL variant About the Guest Amy Patterson, MS, CGC, is a licensed, board-certified genetic counselor in the Department of Genetic Medicine at Johns Hopkins. She works with pediatric and adult patients in the general genetics clinic and the Greenberg Center for Skeletal Dysplasias, including individuals and families affected by hypophosphatasia. About the Series This episode is the first in a three-part educational series about hypophosphatasia. Stay tuned for the next installment . Across the series, we explore the clinical spectrum and diagnosis of HPP, its genetic basis and variable expression, and considerations for genetic counseling and management.

    #407 NFL and Kansas City Chiefs Star Art Still on the Missed Signs of Hereditary Amyloidosis

    What happens when the symptoms of a genetic condition look like the lasting effects of a professional football career? Former NFL defensive end and Kansas City Chiefs star Art Still spent decades attributing carpal tunnel syndrome, trigger finger, back problems, joint and tendon injuries, neuropathy, and other health concerns to football, aging, and ordinary wear and tear. Even when he developed atrial fibrillation, Art’s lifelong discipline and athlete mentality made him believe he could manage his health on his own. Art and his wife, Liz Still, join host Kira Dineen to share how those seemingly disconnected symptoms were eventually traced to hereditary transthyretin amyloidosis, also known as hereditary ATTR or hATTR amyloidosis. During evaluations through the NFL Player Care Foundation wellness program, Art’s healthcare providers looked beyond his individual symptoms and asked about his family health history. That conversation revealed a striking pattern: relatives with serious cardiac, neurologic, and mobility-related conditions, including Art’s older brother, who received a heart transplant, and his nephew, who lived with sickle cell disease and had previously tested positive for the same TTR variant. Genetic testing confirmed that Art carries the V122I variant, also called p.Val142Ile or V142I, in the TTR gene. This variant is found in approximately 3–4% of Black Americans, or about 1 in 25, although carrying it does not necessarily mean someone will develop amyloidosis. For Art and Liz, the diagnosis provided answers, but it also raised questions for their 11 children, 28th grandchild on the way, and extended family. They discuss navigating family conversations about inherited health risks, the value of genetic testing, Art’s evolving trust in healthcare, and why following a treatment plan matters. Through their nonprofit, Still 4 Life, Art and Liz now offer free community presentations focused on awareness, earlier detection, family health history, and self-advocacy. Their goal is to make complicated medical information easier to understand and reach people who may otherwise dismiss their symptoms or hesitate to seek care. Episode Discussion Topics How Art’s “no pain, no gain” athlete mentality shaped his response to symptoms Why professional athletes may normalize pain and avoid disclosing injuries The symptoms Art initially attributed to football, including carpal tunnel syndrome, trigger finger, back problems, neuropathy, joint and tendon injuries, and a torn biceps Why a torn biceps can be a potential warning sign of transthyretin amyloidosis Liz’s early belief that Art’s symptoms were natural consequences of his football career When Art’s cardiac symptoms caused Liz to realize something else might be happening Art’s history of atrial fibrillation and his initial resistance to medication His evaluations through the NFL Player Care Foundation wellness program The family health history questions that helped connect Art’s seemingly unrelated symptoms His brother’s heart transplant His nephew’s sickle cell disease, amyloidosis, and earlier genetic test result Why Art’s nephew was originally evaluated for Marfan syndrome How genetic testing identified Art’s V122I TTR variant The relief of finally understanding the cause of Art’s health problems How the diagnosis changed conversations with their 11 children and extended family Why family health history may be one of the most valuable legacies a family can preserve The difference between carrying a genetic variant and developing symptoms Why ancestry can help identify risk but should not be used to exclude someone from consideration Art’s mistrust of the medical and pharmaceutical industries, and how his perspective evolved What happened when Art reduced and stopped his heart medication without medical guidance Why finding a healthcare team that explains the purpose of treatment is so important How Liz advocated for Art when she realized he was not following his prescribed treatment plan The importance of asking questions and making healthcare decisions with qualified clinicians How Art uses humor and personal storytelling to make medical information approachable Why Art and Liz founded Still 4 Life Meeting people where they are through free community education Encouraging families to discuss their health history and advocate for one another Turning a hereditary diagnosis into a game plan for a healthier community About Hereditary ATTR Amyloidosis Hereditary transthyretin amyloidosis is caused by a disease-associated variant in the TTR gene. The variant makes the transthyretin protein more likely to misfold and accumulate as amyloid deposits in organs and tissues. Depending on the individual and the specific variant, hereditary ATTR amyloidosis can affect the heart, peripheral nerves, autonomic nervous system, digestive system, kidneys, and other parts of the body. Possible warning signs can include cardiomyopathy, heart failure, irregular heart rhythms, neuropathy, carpal tunnel syndrome, spinal stenosis, tendon injuries, swelling, and digestive symptoms. Because these concerns are often evaluated by different specialists, and may be attributed to more common conditions, the underlying diagnosis can be missed for years. Art carries the V122I variant, which is also referred to as V142I or p.Val142Ile under current genetic nomenclature. It is particularly prevalent among people with West African ancestry and is found in approximately 3–4% of Black Americans; however, genetic variants do not conform neatly to racial categories.  Not everyone who inherits a disease-associated TTR variant develops amyloidosis. Anyone concerned about personal symptoms or family history should discuss appropriate evaluation and testing with a qualified healthcare professional. About Art Still Art Still is a former NFL defensive end, College Football Hall of Fame inductee, and rare disease advocate. He was selected by the Kansas City Chiefs with the second overall pick in the 1978 NFL Draft and played 12 professional seasons with the Chiefs and Buffalo Bills. During his decade in Kansas City, Art earned four Pro Bowl selections and was named the Chiefs’ Most Valuable Player twice. After years of orthopedic, neurologic, and cardiac symptoms, Art was diagnosed with hereditary transthyretin amyloidosis in 2023. Art now uses the same team-oriented mindset that shaped his football career to educate communities about amyloidosis, family health history, early detection, and self-advocacy. About Liz Still Liz Still is Art’s wife, care partner, and advocacy partner. She initially believed that many of Art’s symptoms resulted from his years in professional football. When his cardiac problems became more serious, she recognized that something else might be happening and became an important advocate throughout his diagnostic and treatment journey. Following Art’s hereditary amyloidosis diagnosis, Liz helped research the condition, understand its implications for their family, and communicate the information to their children and relatives. She now works alongside Art through Still 4 Life, helping families recognize the importance of asking questions, sharing family health history, and advocating for the people they love. Still 4 Life Art and Liz founded Still 4 Life to increase awareness and encourage earlier detection of amyloidosis and other rare diseases. Through free community presentations, they share Art’s personal experience in approachable language and encourage people to: Learn and document their family health history Discuss patterns of illness with relatives Pay attention to symptoms that may appear unrelated Ask healthcare providers questions Advocate for themselves and their loved ones Learn whether a genetics evaluation may be appropriate Seek medical guidance before changing prescribed treatment Community organizations, healthcare professionals, and other groups interested in hosting an educational presentation can connect with Art and Liz through Still4Life.org.

    #406 Mock Teratogen Genetic Counseling Session: Ozempic, Zoloft, Xanax, and Metformin

    This is our seventh installment in our Mock Genetic Counseling Session Series! In this episode, genetic counselor and teratogen information specialist Sharon Voyer Lavigne and student Edith Atwerebour perform a mock genetic counseling session. The session indication is medication exposures during pregnancy, including Ozempic®, metformin, Zoloft®, and Xanax®. This session was recorded in person, providing a more dynamic and engaging learning experience. Therefore, we highly recommend watching it on YouTube to fully immerse yourself in the interaction. We hope this series is helpful for prospective and current genetic counseling students, as well as the general public, by demystifying the genetic counseling process.  The Actors: Edith Atwerebour is currently a student in the Human Genetics Program at Sarah Lawrence College training to become a genetic counselor. In this mock session, she plays Denise, a 34-year-old woman who is pregnant with her second child and seeking information about medication exposures during pregnancy. The premise of this mock case was developed as part of Atwerebour’s internship with DNA Today. Sharon Voyer Lavigne, MS, LGC, is a licensed genetic counselor, teratogen information specialist, and Coordinator of MotherToBaby Connecticut. She has worked with MotherToBaby Connecticut for more than 28 years and also serves as its Research Coordinator. Lavigne is a Clinical Instructor in the Division of Human Genetics within the Department of Genetics and Genome Sciences at UConn Health. She teaches and trains genetic counseling students, maternal-fetal medicine fellows, OB/GYN residents, and other healthcare professionals. Lavigne received her Bachelor of Science in Biology from Northeastern University and her Master of Science in Human Genetics/Genetic Counseling from Sarah Lawrence College. Through MotherToBaby, she helps patients and healthcare professionals understand the most current evidence about medications and other exposures during pregnancy and breastfeeding. Mock Session Overview: How genetic counselors establish the approximately 3% background risk for birth defects before discussing specific exposures Why the timing, dose, frequency, and duration of a medication exposure matter What is currently known, and still unknown, about semaglutide (Ozempic®/Wegovy®) exposure during early pregnancy Why controlling type 2 diabetes may be more important than the medication exposure itself The role of metformin, insulin, maternal-fetal medicine specialists, and diabetes educators during pregnancy What research suggests about sertraline (Zoloft®) use and the risk for structural birth defects How untreated anxiety and depression can also affect maternal and pregnancy health Possible newborn adaptation symptoms following exposure to certain psychiatric medications Why patients should consult their healthcare providers before reducing or discontinuing medication How therapy, family support, and postpartum planning can complement medication management The role of anatomy ultrasounds and fetal echocardiograms in pregnancy monitoring How MotherToBaby helps patients and healthcare providers navigate exposures during pregnancy and breastfeeding The central takeaway from the session is that Denise’s reported medication exposures are not expected to place the pregnancy at a significantly greater overall risk. Instead, the primary priorities are improving diabetes control, maintaining her mental health, and coordinating care among her obstetrician and other healthcare providers. MotherToBaby Resources: MotherToBaby provides free, evidence-based information about medications and other exposures during pregnancy and breastfeeding. Patients and healthcare providers can contact MotherToBaby by phone, text, email, or live chat. MotherToBaby Pregnancy and Breastfeeding Fact Sheets MotherToBaby: Semaglutide (GLP-1s like Ozempic®, Wegovy®, Rybelsus®) MotherToBaby: Metformin (Glucophage®, Glumetza® and Fortamet®)  MotherToBaby: Sertraline (Zoloft®) MotherToBaby: Alprazolam (Xanax®, Niravam®, Gabazolamine-0.5®) Previous Installments of Our Mock Genetic Counseling Session Series: Episode #311: Cancer Session for Breast and Prostate Cancer Family History Episode #317: Prenatal Session for Advanced Maternal Age Episode #331: Pediatric Session for Autism Episode #351: Cardio Session for Sudden Death of a Family Member Episode #368: Prenatal Session for Increased Nuchal Translucency Episode #373: Pediatric Session for an Abnormal Cystic Fibrosis Newborn Screening Result Disclaimer: Please note that the information provided in this mock genetic counseling session is intended strictly for educational purposes and should not be used for personal medical decision-making. Medication risks and benefits during pregnancy vary based on the individual, medication, dose, timing, and underlying medical condition.

    #405 Why Insurance Denies Genetic Testing, and How to Navigate Coverage

    Genetic testing can change the course of a patient’s care, but accessing the right test is not always straightforward. Behind the scenes, insurance coverage decisions, documentation requirements, prior authorization, denials, appeals, and cost concerns can all influence whether a patient receives timely answers. In this episode of DNA Today, we launch a new special series sponsored by Revvity in this episode exploring the health economics of genetic testing and the real-world systems that shape access to genomic medicine. Host Kira Dineen is joined by Dr. Madhuri Hegde, Senior Vice President and Chief Scientific Officer at Revvity, and Mackenzie Mosera Derby, a pediatric genetic counselor at UW Health. Together, they examine genetic testing access from both the diagnostic laboratory and clinical perspectives exploring why insurance coverage remains so inconsistent, what goes into a prior authorization, why genetic tests are commonly denied, and how clinicians can approach appeals and peer-to-peer reviews. In This Episode, We Discuss The transition from stacked laboratory procedure codes to codes for genes, panels, exomes, and genomes How and why insurance coverage varies among payers and individual health plans Coverage differences across hereditary cancer testing, exome sequencing, genome sequencing, reproductive testing, and population screening How rapid and ultra-rapid genome sequencing may be covered differently from standard genome sequencing The limited coverage available for preventive and population-based genomic testing The coordination required among patients, clinicians, laboratories, and insurance companies Why laboratories offering tests with similar names may differ in technology, interpretation, turnaround time, and clinical support What documentation is typically required for a genetic testing prior authorization How clinicians demonstrate medical necessity and clinical utility Why professional guidelines and peer-reviewed literature can strengthen an authorization request The role laboratories play in benefits investigations, billing assistance, financial support, and prior authorization Why laboratories may perform testing without knowing whether they will ultimately be reimbursed Common reasons insurance companies deny genetic testing Why “this test will not change clinical management” can be an overly narrow interpretation of genetic testing’s value How genetic results may inform surveillance, reproductive decisions, recurrence risks, family members, research eligibility, and patient support The role of hospital test utilization committees Why genetic counselors and geneticists should be represented on utilization review teams How letters of medical necessity (LOMN) and peer-to-peer reviews may support an appeal Why genetic counselors may be prevented from conducting peer-to-peer reviews, even when they were the ordering provider The time clinicians spend educating insurance representatives about genetics Why payer policies frequently lag behind genomic technology and professional recommendations The importance of detailed clinical documentation and accurate diagnostic coding The difference between prior authorization, insurance coverage, and guaranteed payment How self-pay pricing and misleading “no-cost” language can create confusion The potential devaluation of genetic testing and genetic counseling services through complementary or low cost self-pay options  Why improving access requires collaboration among patients, clinicians, laboratories, professional organizations, healthcare systems, and payers About The Guests  Madhuri Hegde, PhD, FACMG, is the Senior Vice President and Chief Scientific Officer at Revvity, where she leads the company’s scientific strategy and oversees Revvity Omics’ global network of laboratories. Dr. Hegde is a medical geneticist and an American Board of Medical Genetics and Genomics-certified diplomate in clinical molecular genetics. Her work focuses on advancing genomic technologies and expanding access to diagnostic testing for patients with rare and inherited conditions. Before joining industry, Dr. Hegde served as Executive Director of the Emory Genetics Laboratory and as a professor of human genetics and pediatrics at Emory University. She has previously joined DNA Today to discuss whole-genome sequencing, Duchenne muscular dystrophy, and rapid genome sequencing in the neonatal intensive care unit. Mackenzie Mosera Derby, MS, CGC, is a pediatric genetic counselor at UW Health and the University of Wisconsin–Madison Division of Genetics and Metabolism. Her work includes pediatric and inpatient genetics, genetic testing utilization, clinical education, and improving the systems through which patients access genetic services. Mackenzie also teaches genetic counseling students and brings experience examining how documentation, insurance authorization, utilization review, and multidisciplinary collaboration affect patient care. Resources American College of Medical Genetics (ACMG) Evidence-Based Clinical Practice Guidelines (EBGs) National Society of Genetic Counselors (NSGC) Billing and Reimbursement Resources (including CPT codes)  American Medical Association (AMA) creation of Current Procedural Terminology (CPT®) codes Centers for Medicare & Medicaid Services (CMS), which is the U.S. federal agency that provides health coverage to more than 160 million through Medicare, Medicaid, the Children's Health Insurance Program, and the Health Insurance Marketplace.  Health literacy paper referenced by Mackenzie sharing that only 12% of U.S. adults had “proficient” health literacy.

    #404 Male Breast Cancer with X-Men Actor and Former Pro Wrestler Tyler Mane

    What happens when someone known for strength, stature, and intimidating roles faces a diagnosis most people do not associate with men?   Tyler Mane is known for playing Sabretooth in X-Men and Deadpool & Wolverine, Michael Myers in Halloween, and Ajax in Troy. Before his acting career, Tyler spent more than a decade wrestling professionally around the world, including appearances with WCW and UWF as Big Sky and Nitron. Recently, Tyler has taken on a very different role: raising awareness about male breast cancer.   Tyler joins host Kira Dineen to share his experience of discovering a breast lump, initially believing it was a lipoma, having his concerns dismissed, and ultimately receiving a breast cancer diagnosis. He opens up about his first instinct to keep the diagnosis private, the embarrassment he initially felt, and what motivated him to speak publicly.

    #402 How Genetic Genealogy Caught the Golden State Killer

    What happens when DNA from a decades-old crime scene meets a family tree created generations later? That combination helped investigators identify the Golden State Killer and transformed how law enforcement approaches some of the country’s most difficult cold cases. Content warning: This episode includes discussions of murder, sexual assault, suicide, and other sensitive topics. In this episode of DNA Today, host Kira Dineen speaks with Paul Holes, a retired cold-case investigator, New York Times bestselling author, podcaster, and television host. During his 27-year career with the Contra Costa County Sheriff’s and District Attorney’s Offices, Paul worked on some of the most infamous cases in American criminal history, including the Zodiac murders, the kidnapping of Jaycee Dugard, and the investigation that ultimately identified Joseph DeAngelo as the Golden State Killer. Paul is also the author of Unmasked: My Life Solving America’s Cold Cases, co-host of the podcast Small Town Dicks, and one of the investigators featured in the television special Celebrity Crime Scene: Marilyn Monroe, available on Hulu. We explore the science, strategy, and ethical complexity behind cold-case investigations. Paul shares how investigators determine whether decades-old evidence still holds value, what kind of DNA evidence would be needed to scientifically resolve the Zodiac case, and why older biological samples create difficult decisions about whether to test now or preserve evidence for future technologies. The episode also dives into the landmark investigation that identified the Golden State Killer. Paul walks through how traditional forensic DNA databases failed to produce a match, why investigative genetic genealogy changed the direction of the case, and how distant relatives’ DNA helped investigators build family trees that eventually led to Joseph DeAngelo. Later in the episode, Paul discusses his latest project, Celebrity Crime Scene: Marilyn Monroe, and how modern virtual reconstruction can be used to reexamine a historic death scene more than six decades later. Episode Discussion Topics Cold-case investigations and how evidence is reexamined decades later How investigators decide which biological samples may still have forensic value The Zodiac Killer case and what would be needed to consider it scientifically solved The challenges of DNA evidence from stamps, envelopes, letters, and other handled items Why finite evidence creates difficult decisions about testing now versus waiting for future technology The role of DNA in linking the Golden State Killer crimes before a suspect was identified Why traditional forensic DNA databases did not solve the case How investigative genetic genealogy helped generate a new lead How distant relatives’ DNA can help identify someone who never uploaded their own DNA The scientific and investigative process behind building genealogical trees from crime-scene DNA How investigators narrowed family branches until Joseph DeAngelo became a viable suspect Reconstructing Marilyn Monroe’s final hours using virtual crime-scene technology What records, photographs, reports, and witness statements can reveal in historical case reviews About Paul Holes Paul Holes is a retired cold-case investigator, New York Times bestselling author, podcaster, and television host. During his 27-year career with the Contra Costa County Sheriff’s and District Attorney’s Offices, he investigated some of the country’s most complex and high-profile cases, including the Zodiac murders, the kidnapping of Jaycee Dugard, and the Golden State Killer case. Paul’s work helped bring national attention to the power of investigative genetic genealogy, particularly through the identification of Joseph DeAngelo as the Golden State Killer. He is the author of Unmasked: My Life Solving America’s Cold Cases, co-host of Small Town Dicks, and appears in Celebrity Crime Scene: Marilyn Monroe.
