Application of proteomics to prenatal screening and diagnosis for aneuploidies.
Current screening for fetal aneuploidies relies on biochemical and ultrasound measurements, and the sensitivity and specificity needs to be improved to reduce the number of pregnant women subjected to invasive diagnostic procedures, such as amniocentesis. Proteomic technologies enable new strategies for discovering biomarkers from complex biological fluids in a high-throughput and sensitive man...
متن کاملNoninvasive prenatal screening for fetal common sex chromosome aneuploidies from maternal blood
Objective To explore the feasibility of high-throughput massively parallel genomic DNA sequencing technology for the noninvasive prenatal detection of fetal sex chromosome aneuploidies (SCAs). Methods The study enrolled pregnant women who were prepared to undergo noninvasive prenatal testing (NIPT) in the second trimester. Cell-free fetal DNA (cffDNA) was extracted from the mother's peripheral ...

Prenatal Diagnosis is the most reliable way of preventing genetic diseases that has been implicated in many countries and has prevented the birth of newborns with different hereditary, congenital and genetic diseases during the past few years. Prenatal diagnosis is actually the use of various diagnostic methods to check the condition of the fetus during pregnancy, because postnatal genetic diso...
متن کاملPrenatal screening for fetal aneuploidies with cell-free DNA in the general pregnancy population: a cost-effectiveness analysis.
OBJECTIVE To estimate the cost-effectiveness of fetal aneuploidy screening in the general pregnancy population using non-invasive prenatal testing (NIPT) as compared to first trimester combined screening (FTS) with serum markers and NT ultrasound. METHODS Using a decision-analytic model, we estimated the number of fetal T21, T18, and T13 cases identified prenatally, the number of invasive pro...
