T21 can be suspected pre-natally with an abnormal quad screen (a-fetoprotein, human chorionic gonado-tropin, estriol, inhibin A) with an 80% to 95% detection rate, or by noninvasive prenatal screening of cell-free placental DNA in the mother's blood with a positive predictive value closer...
As the aDNA record continues to grow, genetic disorders with extremely low rates of prevalence will be able to be more frequently discovered. Methods for screening data, such as the one presented here, will need to be developed and refined for better detection of these afflictionsis. Integrated...

Background Conventional prenatal screening tests, such as maternal serum tests and ultrasound scan, have limited resolution and accuracy. Methods We developed an advanced noninvasive prenatal diagnosis method based on massively parallel sequencing. The Noninvasive Fetal Trisomy (NIFTY) test, combines an ...

Current guidelines suggest screening at school age or when there are clinical symptoms of OSA in Trisomy 21. However, results suggest the need to evaluate and intervene earlier especially in infants with dysphagia. SUPPORT (IF ANY).Cho Yeilim...
To provide accurate individual patient-specific risks for trisomy 21, maternal weight must be taken into account and should be a mandatory data item for screening programmes. Maternal weight correction in the first trimester using free -hCG and PAPP-A can be best achieved using the log-linear pr...
