Purpose: Children born to older parents are at greater risk for genetic abnormalities, such as Down syndrome. The influence of maternal age on Down syndrome is well established but little is known about the genetic consequences of advanced paternal age.
Materials And Methods: Data on the incidence of Down syndrome from 1983 to 1997 (3,419 cases) were obtained from the New York State Department of Health congenital malformations registry.
