[The incidence of constitutional chromosome aberrations]
Abstract
The incidence of constitutional chromosomal abnormalities in livebirths has been estimated at 0.62% from 7 surveys pooling 45,183 newborns. The repartition of these abnormalities is reported and compared to the incidence observed in spontaneous abortuses, perinatal deaths and in normal adults.
