New insights into little known but common birth defect: Congenital diaphragmatic hernia

Although many genetic mutations have been linked to CDH, a new study from the University of Utah School of Medicine is the first to demonstrate a linkage between genetic variation and a physiological mechanism that gives rise to defects in the diaphragm. The research points to a crucial role for connective tissue in CDH, and in guiding normal development of the diaphragm. These findings were published March 25, 2015, in Nature Genetics.

Research like this could tell physicians when and how CDH occurs in fetal development, opening the  door to preventative treatments. “We learned that these defects happen really early – much earlier than previously thought,” says Gabrielle Kardon, Ph.D., associate professor of human genetics and principal investigator on the study.  She stressed there are currently no therapeutic interventions to prevent CDH, and even with surgical patching of the diaphragms CDH is “silently killing half of the affected babies” – referring to the 50 percent mortality rate with this condition. Her lab is poised to test whether drugs can prevent the birth defect in animal models.
