Prenatal diagnosis of genetic syndromes

Genetic syndromes mostly occur sporadically in couples with no prior risk. Ultrasound (US) screening provides a potential tool to detect them successfully. Due to the fact that many of these syndromes are quite rare, the clinical use of routine prenatal ultrasound in their detection has not been fully investigated. We present data on the prenatal diagnosis of nine non-chromosomal genetic syndromes provided by 25 congenital malformation registries across Europe. US led to the prenatal detection of 32% of 536 cases of analysed genetic syndromes, thereby resulting in a 24% reduction in their prevalence at birth, due to termination of pregnancy. The detection rate varies with the different countries’ policies of prenatal screening, the operator's skill, equipment used, the time of the screening and the type and severity of the syndrome presentation.
