Background

Dr. Hilary Vernon is an Associate Professor of pediatrics at the McKusick Nathans Institute of Genetic Medicine at the Johns Hopkins University School of Medicine. She is also an attending physician at Kennedy Krieger Institute.

Dr. Vernon received her undergraduate degree in biochemistry from University of Pennsylvania. She earned her M.D. from Robert Wood Johnson Medical School/UMDNJ and her Ph.D. from Rutgers University. She completed a combined residency in pediatrics and clinical genetics and a fellowship in clinical laboratory biochemical genetics at Johns Hopkins University. Dr. Vernon joined the faculty at the Kennedy Krieger Institute and at Johns Hopkins University in 2011.

Her research focuses on inborn errors of metabolism, which cause disturbances of mitochondrial function, including Barth Syndrome, methylmalonic acidemia and propionic acidemia. She directs the Barth Syndrome Interdisciplinary clinic at the Kennedy Krieger Institute and is the principal investigator of the first intervential clinial trial in Barth Syndrome. She is also the co-director of the Clinical Trials Unit at the McKusick-Nathans Institute of Genetic Medicine.

Dr. Vernon was recognized with the 2010 Francis F. Schwentker Award for Excellence in Research at Johns Hopkins University and the 2011 James B. Sidbury Jr. Fellowship in Biochemical Genetics at Johns Hopkins University. She is board certified in pediatrics, clinical genetics and clinical biochemical laboratory genetics.

Research & Publications

Research Summary

Dr. Vernon's current area of study is in inborn errors of metabolism, which cause disturbances of mitochondrial function, including several different organic acidemias and Barth Syndrome. These are rare disorders, each with an approximate incidence of 1/50,000 - 1/250,000. They have an onset in childhood and a devastating effect on health and quality of life.

Dr. Vernon's lab uses a mass spectrometry-based metabolomics approach to create metabolic profiles of these disorders and select promising analytes from these profiles as potential treatment targets for further study. She is also using cell culture and animal-based models in identifying molecular and metabolic markers.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
