University of Wisconsin veterinary researchers uncover news clues about the cause of common birth defects

Cleft lip and palate are the most common craniofacial birth defects in humans, affecting more than 175,000 newborns around the world each year. Yet despite decades of research, it’s still not known what causes most cases or what can be done to prevent them. But a recent study from the University of Wisconsin School of Veterinary Medicine (SVM) has uncovered new information about orofacial development in mice that researchers believe could one day help reduce the risk of these birth defects in humans.
