Dr. Harry “Hal” Dietz is a professor of pediatrics, an associate professor of medicine and an assistant professor of neurological surgery at the Johns Hopkins University School of Medicine. He is the Victor A. McKusick Professor of Genetics and also serves as the director of the William S. Smilow Center for Marfan Syndrome Research. Recognized as the world’s leading authority on Marfan syndrome, Dr. Dietz conducted genomic mapping and research on therapeutic agents for deficiencies in the genetic protein fibrillin, which is linked to Marfan syndrome. His research contributions have made diagnosis of the condition patient-specific and accurate. He has received more than 50 national and international awards and honors, including the Antoine Marfan Award from the National Marfan Foundation and the Art of Listening Award from the American Heart Association. Dr. Dietz is an ad hoc reviewer for 19 different organizations, including the American Journal of Cardiology, the Archives of Pediatric and Adolescent Medicine, and the Journal of Clinical Investigation. Over more than two decades, Dr. Dietz has mentored 75 predoctoral and postdoctoral researchers. He has authored 282 original publications in peer-reviewed journals, 25 textbook chapters, and 239 abstracts, and has also delivered more than 440 lectures on Marfan syndrome and related genetic disorders. Dr. Dietz completed his B.S. at Duke University and received his M.D. from the SUNY Upstate School of Medicine. He completed a pediatric residency and a cardiology fellowship at Johns Hopkins University before joining the faculty in 1992. Dr. Dietz is rated as an Advanced provider by MediFind in the treatment of Vici Syndrome. His top areas of expertise are Caudal Duplication, Neu Laxova Syndrome, Early Infantile Epileptic Encephalopathy, and Cardiomyopathy Hypogonadism Metabolic Anomalies.

Dr. Ada Hamosh is the Dr. Frank V. Sutland Professor of Pediatric Genetics in the Departments of Genetic Medicine and Pediatrics. Since 2002, she has served as clinical director of the McKusick-Nathans Institute of Genetic Medicine, now Department of Genetic Medicine and scientific director of the Online Mendelian Inheritance in Man® (OMIM), a catalog of more than 16,800 human genes and genetic disorders created by Dr. Victor A. McKusick. Her research centers the molecular basis of Mendelian disorders, the integration of genetics into clinical practice and the diagnosis and management of inborn errors of metabolism. Dr. Hamosh earned a bachelor’s degree in biology from Wesleyan University, a medical degree from Georgetown University School of Medicine and a master’s of public health from Johns Hopkins University School of Public Health. She later completed a fellowship in medical and biochemical genetics from the Johns Hopkins School of Medicine, before joining the Johns Hopkins faculty in 1992. Dr. Hamosh began her genetics career focusing on cystic fibrosis, serving as coordinator of the International Cystic Fibrosis Genotype-Phenotype Consortium. She served as chair of the Maryland State Advisory Council for Hereditary & Congenital Disorders from 2001-2009, during which time she also served on the executive committee of the Genetic Counseling Training Program, run by Johns Hopkins University and the National Human Genome Research Institute. Dr. Hamosh has authored more than 128 publications on a variety of topics. In addition, she is a member of 16 professional associations and advisory committees including the American Society of Human Genetics, the Steering Committee of the Global Alliance for Genomics and Health, and the executive board of the Human Genome Organization, of which she will be President from 2023-2025. Dr. Hamosh was recognized in Baltimore magazine as one of the region’s top doctors in 2013, and 2016-2020. Dr. Hamosh is rated as a Distinguished provider by MediFind in the treatment of Vici Syndrome. Her top areas of expertise are Methylmalonic Acidemia, Maple Syrup Urine Disease, Ornithine Transcarbamylase Deficiency, Phenylketonuria (PKU), and Deep Brain Stimulation.

Dr. Jaqueline Weissman is an assistant professor in the Department of Neurology, Kennedy Krieger Institute, Department of Pediatrics Johns Hopkins Hospital and Institute of Genomic Medicine at Johns Hopkins Hospital. She is also director of the Center for Tuberous Sclerosis and Related Disorder at Kennedy Krieger Institute. She focuses on genetic and epigenetic causes of neurodevelopmental disorders - particularly intellectual disability - and how specific genetic and epigenetic changes lead to specific neuroanatomic, neurophysiologic and cognitive phenotypes. She is also interested in developing specific cognitive profiles in genetic syndromes as potential outcome measures for trials and to help localize deficits. Currently most of her research is centered around Kabuki Syndrome. Dr. Weissman received her B.A. with. Dr. Harris is rated as an Advanced provider by MediFind in the treatment of Vici Syndrome. Her top areas of expertise are Borjeson-Forssman-Lehmann Syndrome, Coffin-Lowry Syndrome, Galactosialidosis, and Odontotrichomelic Syndrome.
