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 ...
متن کاملNoninvasive prenatal testing of aneuploidies: where are we now?
Prenatal diagnosis of chromosomal aneuploidies is the most frequent prenatal test offered to pregnant women. In most cases, they are recommended in the following circumstances: maternal age of 35 years or above; positive firstor second-trimester screening test results, and increased risk of fetal aneuploidies due to family history. During the first trimester, screening tests include: nuchal tra...
متن کاملNoninvasive prenatal diagnosis of common aneuploidies by semiconductor sequencing.
Massively parallel sequencing (MPS) of cell-free fetal DNA from maternal plasma has revolutionized our ability to perform noninvasive prenatal diagnosis. This approach avoids the risk of fetal loss associated with more invasive diagnostic procedures. The present study developed an effective method for noninvasive prenatal diagnosis of common chromosomal aneuploidies using a benchtop semiconduct...
متن کاملPrenatal detection of fetal aneuploidies using transcervical cell samples.
In the course of an investigation aimed at detecting the presence of trophoblastic cells in the endocervical canal of pregnant women between 7 and 17 weeks of gestation, several cases of aneuploidies were observed using a fluorescent in situ hybridisation (FISH) assay. The cases include fetal chromosome 21 and 18 trisomies, triploidy and sex chromosome aneuploidies. The results were confirmed b...
