About Us



Parabase Genomics’ is committed to improving neonatal care through the development of early diagnostics for actionable inherited disorders. The company’s NewbornDx Tests™ are designed to be rapid and less invasive, using dried blood spots, and incorporate the most damaging disorders. Physicians can now make precise treatment decisions based on an individual’s molecular profile rather than severe symptomology. NewbornDx will assist neonatologists to make prompt and informed decisions while the patient is still in the hospital by matching them to the best treatment and clinical trial options. 

The company’s advisors are world leaders in newborn medicine, genomic technologies and informatics.

Directors and Advisors

Edwin Naylor, Ph.D., MPH

External Board of Directors

Dr. Naylor is a recognized expert in the field of Newborn Screening for nearly four decades. He trained in the laboratory of Robert Guthrie, who pioneered Newborn Screening worldwide. In 1994 Dr. Naylor founded a private newborn screening and research laboratory (NeoGen Screening, Inc) that carried out Newborn Screening for all newborns in the District of Columbia, Mississippi, Nebraska, and Pennsylvania; and was the first to introduce tandem mass spectrometry and primary DNA screening as a routine newborn screens. The company was also a major developer of second-tier DNA confirmation on dried blood specimens. The laboratory was sold in 2003 to Pediatric Medical Group and later resold to Perkin Elmer. Dr. Naylor is actively involved in consulting and research including with Parabase Genomics. Dr. Naylor has a M.P.H from University of Pittsburg in Human and Population Genetics, a Ph.D from University of Utah in Genetics and undergraduate degree from Middlebury College in Biology and Chemistry.

Dietrich A. Stephan, PhD.

External Board of Directors

Dr. Stephan is a geneticist, entrepreneur and recognized leader in the field of personalized medicine. He is on the Board of Directors of several organizations, including the Personalized Medicine Coalition, and continues to found biotechnology companies, including Silicon Valley Biosystems (SV Bio), Aueon, Amnestix, and DiaVacs. Dr. Stephan has published over 140 articles in peer-reviewed scientific journals, and he is a member of the Scientific Advisory Boards of many companies. Among numerous honors and awards, Dr. Stephan has won the Bio-IT World Grand Prize for Discovery Research in 2005, and the "Most Influential in Bringing Genomics to the Clinic" award at the Consumer Genetic Conference in 2010. In 2006, Dr. Stephan founded Navigenics, Inc., a pioneering consumer genomics company, and later served as the company's Chief Science Officer. Prior to that, he served as part of the leadership team of the Translational Genomics Research Institute (TGen), building it into one of the largest free-standing research institutes in the world. His roles at the Institute were Chairman of the Neurogenomics Department, Professor within the Institute, and Deputy Director for Discovery Research of the Institute overall. Dr. Stephan also served as Chairman of the NIH Neuroscience Microarray Consortium for seven years. He was Executive Director of the Gene Partnership at Harvard Medical School and Children's Hospital Boston, where he architected and capitalized a groundbreaking genomic medicine pediatric program, as well as a genomic cancer program at Fox Chase Cancer Center. Dr. Stephan brought next-generation genome sequencing (NGS) to these clinical settings, with associated clinical decision support and sustainable business processes. Dr. Stephan earned a B.Sc. in biology from Carnegie Mellon University and a Ph.D. in Human Genetics from the University of Pittsburgh Graduate School of Public Health, where he was a 2012 “Legacy Laureate”.
