First-trimester prenatal diagnosis of Ellis-van Creveld syndrome using linked microsatellite markers

We report a personal experience of first-trimester prenatal diagnosis of Ellis-van Creveld (EvC) syndrome based on typing of microsatellite markers flanking the EvC locus. An heterozygous fetus was diagnosed with a diagnostic accuracy of 96 per cent. The DNA prediction was confirmed by ultrasound at 22 weeks of gestation and by clinical evaluation at birth.
