#283 Cardiogenetics with Blueprint Genetics

Ornithine transcarbamylase deficiency (OTC-D) is the most common urea cycle disorder (UCD) and is inherited in an X-linked manner. Females with OTC-D are affected to varying degrees. Some female patients will develop chronic and nonspecific symptoms, such as headaches, and all women with OTC-D are at risk of experiencing hyperammonemic crises. Additionally, recent studies suggest these women can experience neurocognitive changes even though they may appear to be “asymptomatic” or have mild symptoms. As our understanding of the disease has evolved, so too have the ways in which we refer to these women and approach their care.
 
In this episode, we’re delving into the evolution of caring for heterozygous females with OTC-D, including the unique challenges to diagnosis and management of these patients with variable and nonspecific symptoms.
 
Joining us are two esteemed guests well-versed in the unique needs of females with OTC-D.
 
Annette Feigenbaum, MBChB, FRCPC, DABMG (Rady Children’s Hospital and University of California San Diego), is a metabolic geneticist with over 30 years of experience in the field. She recently retired from her clinic role at Rady Children’s Hospital, where she served as an associate physician for the past 12 years. She and her team recently published a case report on the prenatal and postpartum management of a female with OTC-D. She has also published an overview of the challenges of managing female heterozygotes with OTC-D.
 
Joshua Baker, DO (Ann & Robert H. Lurie Children’s Hospital of Chicago), is a metabolic geneticist and the director of the Inborn Errors of Metabolism Program in the Division of Genetics, Genomics, and Metabolism. He and his team recently published a case report on a family with variable manifestations of OTC-D.
 
On This Episode, We Discuss:
How our understanding and approaches to managing heterozygous females with OTC-D have changed over time
Management challenges unique to females with OTC-D and best practices for encouraging continued engagement in their care
Opportunities to support the care of females with OTC-D

#282 The Evolution of Caring for Females With OTC Deficiency

A physician-scientist father shares his heartbreaking story of the death of his daughter who was diagnosed with Tay-Sachs disease and how it motivated him to become the CEO of JScreen to prevent this experience in other families. 
 
This episode was originally recorded for another podcast Kira Dineen produces, It Happened To Me, and which is hosted by Cathy Gildenhorn and Beth Glassman. 
 
Matt Goldstein is a physician-scientist and entrepreneur. He has founded companies, built R&D teams, and led strategy and execution of both pre-clinical research and clinical development. Prior to joining JScreen and Emory University, Matt was a Partner at Related Sciences, a venture creation firm. As an entrepreneur at Third Rock Ventures he spent a decade building and operating Third Rock portfolio companies. He was responsible for building and leading the Immunology program at Tango Therapeutics, the centerpiece of Tango’s strategic multi-billion dollar partnership with Gilead Sciences, Inc. He also served as the development head for Tango’s lead program which entered the clinic in 1H 2022. Matt was a co-founder of Neon Therapeutics leading Translational Medicine and Early Development through completion of their first clinical study and initial public offering. He is a graduate of Swarthmore College and the MD/PhD program at Stanford University, where he pioneered novel cancer immunotherapies in the lab of Ron Levy, MD. He completed his clinical training in Internal Medicine at Harvard Medical School, Brigham & Women’s Hospital. He lives in Boston with his wife, Myra, their second daughter Kaia and son Ezra. His oldest daughter Havi died on January 20th, 2021 of Tay-Sachs disease.
 
A quick update that during the episode Matthew mentioned there are 4,000 genetic counselors in the USA, this number has now surpassed 5,000.  
 
During the episode, Matthew recommends the book Bearing the Unbearable: Love, Loss, and the Heartbreaking Path of Grief by Dr. Joanne Cacciatore. 
 
Check out his wife, Myra Sack’s organization, Emotion, which is for grieving individuals to find community and cope with loss. In the next episode of It Happened To Me Myra Sack will come on the show to share about Emotion and her upcoming book, Fifty-Seven Fridays, which consists of memoirs from Matt and Myra, Havi’s diagnosis, and how they celebrated her life.
