Research team discovers possible genetic mechanism behind congenital heart defects
... "It was previously believed that all cells during development
contained the same chromatin remodelling proteins that unwind DNA, a process that is important for genes to be turned on. However, we identified one of these proteins, called Baf60c, that is expressed specifically in the developing heart," said Dr. B...
