About Hal C. Dietz III

Professional Titles

  • Investigator, Howard Hughes Medical Institute
  • Victor A. McKusick Professor of Medicine and Genetics

Primary Academic Title

Professor of Genetic Medicine

Background

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.

Research Summary

Dr. Dietz and his laboratory team are interested in the development and homeostasis of the arterial wall, and other diseases of the connective tissue.

One goal is to understand genetic factors that predispose to aortic aneurysm, a condition accounting for 1-2 percent of deaths in industrialized countries. Their initial approach has been to study Marfan syndrome (MFS), a genetic disease that includes aortic aneurysm as part of the condition and that is caused by mutations in a single gene. It is anticipated that a comprehensive understanding of the cause, progression, and modulation of MFS will promote a greater understanding of vascular wall biology.

Other vascular disorders currently being studied include vascular Ehlers-Danlos Syndrome, and an aggressive aneurysm phenotype called Loeys-Dietz syndrome. We have shown that the multisystem pathogenesis of each of these disorders relates to crosstalk between the transforming growth factor b (TGFb), angiotensin II (AngII) and mitogen-activated protein kinase pathways. These pathways can be targeted carefully in mouse models to provide a strong scientific basis for therapeutic intervention in humans with these diseases.

A second major interest of the laboratory is to understand the mechanism of nonsense-mediated mRNA decay; to evaluate its basic biologic purpose; and to assess its role as a potent modulator of disease severity in a wide variety of genetic disorders.
