Ravgen

With the goal of changing the paradigm of prenatal diagnostics, Ravgen was founded in 2000 by Dr. Ravinder Dhallan, M.D./Ph.D., M.B.A., a graduate of The Johns Hopkins University School of Medicine. The current paradigm is almost exclusively focused on Downs syndrome testing, however, there are many other genetic conditions and reasons to offer patients prenatal diagnosis. For example, there are hundreds of single gene disorders, such as cystic fibrosis and sickle cell anemia among others, which can be better treated with early diagnosis. Dr. Dhallan and his team have spent the last decade working with fetal DNA present in the mother’s blood developing safe, noninvasive tests to expand upon the current options available to patients.
