Twin Pregnancy discordordant for Downs syndrome: Case Report
Keywords:
Twin Pregnancy, Nuchal Translucency, Robertsonian Translocation, Down Syndrome, Fetal Reduction
Abstract
The work presented is a clinical and genetical trial of a couple with a reproductive failure and a family history of chro-mosomal abnormalities. The most reliable and accurate methods used for antenatal diagnosis of Down syndrome fetuses are highlighted.
