DNA Today: A Genetics Podcast #273 ENPP1 Deficiency Disorders with Inozyme
As we delve into the intricacies of ENPP1 Deficiency Disorders, Dr. Yves Sabbagh and Christine O’Brien provide invaluable insights into genetics, diagnostics, treatment, and collaborative efforts between the patient community and pharmaceutical companies. Join us in this illuminating conversation, as we navigate the complexities of GACI and explore avenues for a brighter future in managing these conditions.
Yves Sabbagh, PhD, is senior vice president and chief scientific officer, joining Inozyme in October 2020. Dr. Sabbagh brings to Inozyme more than 20 years of experience in rare genetic disorders and mineral metabolism with responsibilities leading to the identification and evaluation of novel therapeutic approaches and translating them into clinical candidates.
Prior to joining Inozyme, Dr. Sabbagh served as the head of Rare Renal and Musculoskeletal Diseases research at Sanofi. Prior to that executive role, he held scientific roles of increasing responsibility at Sanofi and Genzyme Corporation spanning endocrine, renal and rare bone diseases including driving the strategy for bone indications. Prior to his corporate experience, he was an instructor at the Harvard Medical School in the Endocrine unit. Dr. Sabbagh has co-authored more than 40 peer-reviewed publications and book chapters and is a member of several scientific societies. Dr. Sabbagh received a BSc in biochemistry from McGill University, an MSc in microbiology from Université Laval and a PhD in biology from McGill University.
Christine O’Brien lives outside of Boston, Massachusetts with her husband Michael and their 3 children. Her two oldest children are both living with ENPP1 Deficiency. Her husband and son also have Loeys-Dietz Syndrome. She is a founding member and co-president of GACI Global, the only patient advocacy group that exists for patients with GACI / ARHR2 caused by ENPP1 Deficiency or ABCC6 Deficiency. Prior to joining the ranks of medical mamas everywhere who manage therapies, appointments, and medications, she was an elementary school guidance counselor. Today, in addition to her work with GACI Global, Christine currently juggles raising children with part time jobs as a photographer and the director of customer service at British Swim School of Greater Boston.
