Researchers uncover new clues about links between parent age and congenital disorders

A new study found that the link between paternal age and rare congenital disorders is more complex than previously thought. Researchers discovered that while older fathers are more likely to have children with certain bone and heart malformations, some genetic mutations associated with these conditions do not increase with paternal age.
