Mutations in genes that occur spontaneously may contribute to congenital heart disease in children, according to a new study.
These mutations — which arise after conception, rather than being inherited from a parent — may contribute to about 10 percent of cases of congenital heart disease in children, the study said.
Congenital heart disease is a group of heart defects (such as holes, or missing parts of the heart), and is the most common type of birth defect in the United States. About 40,000 babies are born each year with congenital heart disease.
