Methods:Screening was performed in 7096 singleton pregnancies. The estimated risk for trisomy 21, the detection rate (DR), false positive rate (FPR) and the cut-off nuchal translucency thickness to obtain a 5% FPR were calculated. Results:The median maternal age was 28.6 years. The estimated r...

The risk of trisomy X increases with advanced maternal age. The phenotype in trisomy X is hypothesized to result from overexpression of genes that escape X-inactivation, but genotype-phenotype relationships remain to be defined. Diagnosis during the prenatal period by amniocentesis or chorionic villi ...
Trisomy 21 carries a high risk of CHD; approximately 40–50% of the patients are affected. Atrioventricular canal type defects, also called endocardial cushion defects, occur in 60% of patients with trisomy 21 and CHD. Conversely, approximately 60% of liveborn infants with a complete common ...
你好：你描述的检查结果还的低风险的。可以继续妊娠和定期的孕检。
This criteria may, as well, be expressed by a pathological threshold of NT varying with maternal age and gestational age. Without questioning that women aged of 38 years or older are a high-risk group, this approach should allow an improvement of the prenatal screening for trisomy 21. 展开 ...
