New gene linked to congenital heart defects

Researchers from the UC San Diego School of Medicine and colleagues have identified a new gene, ETS-1, that is linked to human congenital heart defects. The landmark study, recently published online in the journal of Human Molecular Genetics, provides important insights into some of the most prevalent forms of congenital heart defects in humans, including ventricular septal defects and potentially hypoplastic left heart syndrome, a uniformly fatal heart abnormality.
