Prenatal screening can detect some of these genetic disorders before a child is even born. Genetic testing helps lead to a trisomy diagnosis early during pregnancy. Normally, each pair would contain two chromosomes, but a third chromosome forms and attaches to the pair, creating a trisomy, which literally translates to three bodies..

If the test finding mosaic trisomy 15 is a chorionic villus sampling, then there is a chance that all the trisomy 15 cells are only in the placenta and not in the baby (confined placenta mosaicism). According to the medical literature, although individuals with trisomy 15q25-qter have many of the characteristic abnormalities typically associated with the disorder, there may be some differences.
