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 Nijmegen Breakage Syndrome. Her top areas of expertise are Odontotrichomelic Syndrome, Kabuki Syndrome, 3MC Syndrome, and Coffin-Lowry Syndrome.

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 Nijmegen Breakage Syndrome. His top areas of expertise are Snyder-Robinson Syndrome, Abruzzo-Erickson Syndrome, Costello Syndrome, and WAGR Syndrome.

Dr. Tom Crawford has been a member of the Department of Neurology since 1987. He is co-director of the MDA clinic for Neuromuscular Disorders and Neurologist for the Ataxia Telangiectasia Clinical Center at Johns Hopkins. His practice involves general child neurology with a principal interest in caring for children with neuromuscular, neuromotor, and ataxic disorders. Primary research interests involve the basic science and clinical characterization of two important neurologic disorders that affect children: Spinal Muscular Atrophy and Ataxia Telangiectasia. He is also actively involved in the Biology of neurofilaments by characterization of transgenic animal models. He is on the Medical and Scientific Advisory Boards of Families of Spinal Muscular Atrophy, and the Medical Advisory Committee for the Muscular Dystrophy Association. He is the Neurologist for the Ataxia Telangiectasia Clinical Center at Johns Hopkins, which has evaluated almost half of the known patients with this disorder in the United States. Additional specific clinical interests include evaluation and treatment of children with brachial plexus palsies. Dr. Crawford received his medical degree from the University of Southern California. He completed a pediatric internship and residency at the Pediatric Pavilion of the Los Angeles County / University of Southern California Medical Center, followed by a pediatric chief residency. He completed his training in Neurology with Special Qualification in Child Neurology at the Los Angeles Childrens Hospital. He then traveled east to the laboratory of Dr John Griffin at Johns Hopkins for a fellowship in Neuromuscular Disorders. Prior to medical training and Neurology residency, he majored in Psychology and Religion at Yale College. Dr. Crawford has published extensively and presented nationally and internationally. He has an active role in teaching medical students and residents in neurology. In addition, Dr. Crawford has special interest and experience in EMG studies of children and adults. Dr. Crawford is rated as a Distinguished provider by MediFind in the treatment of Nijmegen Breakage Syndrome. His top areas of expertise are Primary Lateral Sclerosis, Spinal Muscular Atrophy (SMA), Ataxia-Telangiectasia, and Spinal Muscular Atrophy Type 2.
