Dr. Bruce Gelb is a pediatric cardiologist at the Mount Sinai School of Medicine. He trained in pediatrics at Columbia-Presbyterian Medical Center and in pediatric cardiology at Texas Children's Hospital. Dr. Gelb is pursuing molecular cardiology/genetics research on inherited cardiovascular disease, particularly congenital heart defects. His group has discovered several disease genes including those underlying Noonan syndrome and related disorders, which are RAS signaling defects
