The state of congenital heart disease.

In this special issue of the American Journal of Medical Genetics Part C, we focus on the "State of Congenital Heart Disease." We anticipate that after viewing this journal, the reader will be up-to-date on the epidemiology of congenital heart disease (CHD), the genetic basis of CHD, ethical concerns, and the global impact of CHD. And most importantly, we are confident that this special issue conveys the message that CHD is complex and that much work is still needed in genetic and genomic research. Published 2020.
