Detection of fetal subchromosomal abnormalities by sequencing circulating cell-free DNA from maternal plasma.
BACKGROUND The development of sequencing-based noninvasive prenatal testing (NIPT) has been largely focused on whole-chromosome aneuploidies (chromosomes 13, 18, 21, X, and Y). Collectively, they account for only 30% of all live births with a chromosome abnormality. Various structural chromosome changes, such as microdeletion/microduplication (MD) syndromes are more common but more challenging ...
متن کاملFetal RHD genotype detection from circulating cell-free fetal DNA in maternal plasma in non-sensitized RhD negative women.
OBJECTIVE To examine the performance of the SensiGene Fetal RHD Genotyping Laboratory Developed Test (RHD Genotyping LDT) using circulating cell-free fetal DNA (ccff DNA) extracted from maternal plasma. METHODS ccff DNA was extracted from maternal blood from non-sensitized women with singleton pregnancies in two cohorts, one with a serotype reference (11-13 weeks' gestation) and one with the ...
متن کاملAn Effective Method for Detecting Y-chromosome Specific Sequences of Circulating Fetal DNA in Maternal Plasma During the First-trimester
Background and Aims: New advances in the use of cell-free fetal DNA (cffDNA) in maternal plasma of pregnant women has provided the possibility of applying cffDNA in prenatal diagnosis as a non-invasive method. One of the applications of prenatal diagnosis is fetal gender determination. Early prenatal determination of fetal sex is required for pregnant women at risk of X-linked and some endocrin...
متن کاملDetection and quantification by homogeneous PCR of cell-free fetal DNA in maternal plasma.
Prenatal diagnosis of genetic disorders has traditionally relied on invasive procedures such as amniocentesis and chorionic villus sampling (CVS). As these procedures carry a small but significant risk of pregnancy loss, a convenient noninvasive prenatal diagnostic has long been sought. Although fetal cells circulating in the maternal blood have been used for prenatal screening, because of thei...
متن کاملO-45: Quantification of Cell-Free-Fetal-DNAfrom Maternal Plasma for the First Time in Pakistan:Diagnosis of Genetic Disorders
Background: Current prenatal diagnosis requires invasive testing which carries a 1-4% procedure-related-risk of miscarriage; hence, non-invasive techniques are desired. The recent demonstration of cell-free-fetal-DNA enriched from maternal plasma has opened new possibilities for non-invasive-prenatal-diagnosis of not only genetic-disorders such as β-thalassaemia and haemophilia but also chromos...
