    On Rare Innovators: Nasha Fitter is Redefining the Rare Disease Playbook – “Who says we can’t do this?”

    In this episode of On Rare Innovators, Mandy Rohrig, Senior Director of Patient Advocacy at BridgeBio, and David Rintell, Head of Patient Advocacy at BridgeBio, talk with Nasha Fitter, a parent, entrepreneur, and rare disease leader whose determination was reshaped the day her daughter Amara was diagnosed with FOXG1 syndrome. Drawing on a career defined by bold pivots and purpose-driven problem solving, Nasha is challenging long-held assumptions about what small, rare disease communities can achieve. From building the FOXG1 Research Foundation to co-founding Citizen Health, she has pushed for new models of data, drug development, and patient empowerment. Nasha’s story is a reminder that innovation often begins with a single question: “Who says we can’t do this?”

    "It’s good to be alive." Greg is living with LMNA cardiomyopathy

    Greg’s journey with LMNA cardiomyopathy, a rare inherited heart condition, began in high school when he experienced sudden episodes of rapid, irregular heartbeats during track practice. The cause remained a mystery for years, leading to misdiagnoses and untreated disease progression. During that time, Greg faced life-threatening arrhythmias and required several implanted devices before finally receiving a heart transplant. That experience, and the challenges that came before it, ultimately inspired his passion to create change and help others facing the same uncertainty. In this episode of On Rare, David Rintell, Head of Patient Advocacy at BridgeBio, and Mandy Rohrig, Senior Director of Patient Advocacy at BridgeBio, speak with Greg about the long road to diagnosis, the emotional impact of learning he had passed the condition on to his children, and his transformation into an advocate as president of the DCM Foundation. He also shares how his personal experience led to the launch of Everygene, a free genetic testing program for people with cardiomyopathies. Dr. Clayton Beard, Chief Scientific Officer at BridgeBio Gene Therapy, provides a high-level medical overview of LMNA-related dilated cardiomyopathy, a form of heart disease caused by mutations in the LMNA gene that compromise the structural integrity of heart cells and disrupt electrical signaling. He explains how these changes can cause dangerous arrhythmias, weaken the heart muscle, and lead to heart failure, making LMNA cardiomyopathy one of the most severe genetic forms of the condition. Dr. Beard also highlights the importance of early genetic testing for at-risk families, the role of research in improving detection and treatment, and how a better understanding of LMNA can lead to life-saving interventions.

    “I’m still very grateful for the life that I’ll have.” Cerys is living with Limb-Girdle Muscular Dystrophy type 2i/R9

    Before she turned eight, Cerys had already faced two diagnoses, only one of which she truly understood. While being diagnosed with celiac disease as a child, unusually high CK levels in her blood pointed to a deeper issue: limb-girdle muscular dystrophy type 2I/R9 (LGMD2I/R9). In this episode of On Rare, David Rintell, Head of Patient Advocacy at BridgeBio, and Mandy Rohrig, Senior Director of Patient Advocacy at BridgeBio Gene Therapy, speak with Cerys, a 23-year-old living in Wales, about living with LGMD2I/R9. She shares how she’s navigated symptom progression, adapted to using mobility aids, and discovered the power of telling her story through her podcast, Unbalanced. When Cerys was first diagnosed with LGMD2I/R9 at age seven 7 years old, she didn’t fully understand the diagnosis. Her parents carried the emotional weight, trying to protect her from fear of what was ahead. It wasn’t until her muscle weakness became impossible to ignore, at 12 years old, that the condition began to define her daily life. From navigating stairs and driving to embracing a wheelchair, Cerys has had to adapt physically, emotionally, and socially, all while managing her energy levels so that she can continue to do the activities she loves. She finds strength in the LGMD community and hope in research, representation, and connection. In 2023, she launched Unbalanced to amplify stories like hers because growing up, she didn’t see anyone with a disability who looked like her. Now, she’s determined to be that voice for others. Dr. Anna Talaga, Director of Medical Affairs at ML Bio Solutions (a BridgeBio affiliate), provides a medical overview of LGMD. LGMDs are a group of genetic diseases that cause progressive muscle weakness and wasting, particularly in the shoulders, hips, and thighs. In some people, the heart and respiratory muscles may be impacted. Unlike many genetic conditions that are caused by a mutation in a single gene, LGMD can result from mutations in many different genes because they all affect the same protein complex that supports and stabilizes muscle fibers. LGMD type 2I/R9 (LGMD2I/R9), specifically, is caused by mutations in the FKRP gene, which is critical for maintaining muscle fiber integrity. Diagnosis typically begins with symptoms like difficulty walking, climbing stairs, or standing from a seated position, and is confirmed through genetic testing. LGMD2I/R9 is a progressive disease and there are currently no approved treatments that slow or stop its progression.

    “It’s important to stay connected” Daniel is living with Tuberous Sclerosis Complex (TSC)

    Seizures, sleepless nights, and mysterious white patches on his skin marked the beginning of Daniel’s journey with Tuberous Sclerosis Complex (TSC). Diagnosed at age 6, Daniel faced a childhood filled with MRIs, EEGs, and specialist visits, often requiring cross-country travel for coordinated care. In this moving episode of On Rare, David Rintell, Head of Patient Advocacy at BridgeBio, and Mandy Rohrig, Senior Director of Patient Advocacy at BridgeBio Gene Therapy, speak with Daniel, a 31-year-old living in Seattle, about growing up with TSC, the emotional toll of visible symptoms, and the stigma he faced from peers. He reflects on the cognitive and mood impacts of TSC, including OCD and outbursts, and how he often kept to himself to feel more accepted. Today, Daniel is an active advocate in the TSC community, emphasizing the importance of connection, representation, and finding support among those with shared experiences. As he puts it, “You have to find your people.” Che-Wei Chang, Principal Scientist at BridgeBio, presents a medical overview of Tuberous Sclerosis Complex (TSC), a rare genetic disorder marked by seizures and benign tumors throughout the body. TSC results from a spontaneous mutation in a single copy of the TSC1 or TSC2 gene, which normally inhibit mTOR, an enzyme that regulates cell growth. Loss of this inhibition leads to mTOR hyperactivation, leading to abnormal cell proliferation and tumors in the brain, kidneys, skin, and other organs. Diagnosis typically involves identifying tubers in the brain along with tumors in other organs and is confirmed through genetic testing. Treatments include mTOR inhibitors, which are effective against many TSC-related tumors, and anti-seizure medications, although drug resistance is common.

    “We just thought we were clumsy”. Katie and Allie are living with late-onset Tay-Sachs disease

    Katie and Allie’s story began in childhood with unexplained clumsiness and subtle symptoms that intensified over time. After years of searching for answers, Katie was diagnosed with late-onset Tay-Sachs (LOTS), a rare neurodegenerative disease. Further testing confirmed her twin sister Allie’s diagnosis as well. Despite facing daily challenges ranging from mobility issues to emotional strain, the sisters have become passionate advocates, raising over $1 million for research and awareness. With humor, grit, and the support of their family—especially their powerhouse mom—they continue to live fully and inspire the rare disease community. In this moving episode of On Rare, David Rintell, Head of Patient Advocacy at BridgeBio, and Mandy Rohrig, Senior Director of Patient Advocacy at BridgeBio Gene Therapy, speak with Katie and Allie, who share their experience with late-onset Tay-Sachs. The episode explores how Tay-Sachs, typically diagnosed in childhood, can present in adulthood, the emotional toll of navigating a progressive rare disease, and the resilience of a close-knit sibling duo who’ve turned advocacy into action.   Diana Jussila, Director of Family Services at the National Tay-Sachs & Allied Diseases Association (NTSAD), provides essential insights into late-onset Tay-Sachs disease, a rare, progressive, neurodegenerative condition caused by mutations in the HEXA gene leading to deficiency of the Hex A enzyme. Without this enzyme, toxic substances accumulate in the brain and spinal cord, resulting in symptoms like muscle weakness, balance issues, speech difficulties, and psychiatric challenges. With no approved treatments and only supportive care available, community connection, advocacy, and ongoing research are vital lifelines for those living with late-onset Tay-Sachs disease.
