Current prenatal diagnosis for fetal aneuploidies (including trisomy 21 [T21]) generally relies on an initial biochemical serum-based noninvasive prenatal testing (NIPT) after which women who are deemed to be at high risk are offered an invasive confirmatory test (amniocentesis or chorionic villi sampling for a fetal karyotype), which is associated with a risk of fetal miscarriage. Recently, ge...
Utilizing epigenetic (DNA methylation) differences to differentiate between maternal peripheral blood (PBL) and fetal (placental) DNA has been a promising strategy for non-invasive prenatal testing (NIPT). However, the differentially methylated regions (DMRs) have yet to be fully ascertained. In the present study, we performed genome-wide comparative methylome analysis between maternal PBL and ...
This article investigates the role of historical references and arguments in current policy debate on non-invasive prenatal testing (NIPT) Germany. It analyses major documents opinion statements, including recent parliamentary (2019). The implementation NIPT is accompanied by concerns strong criticism, particularly Many perceive new test to be a problematic step that facilitates selective pract...
Introducción. La prueba prenatal no invasiva (NIPT, por su sigla en inglés) es una de tamización aneuploidías fetales con mayor sensibilidad y especificidad que la bioquímica tradicional. Objetivo. Evaluar concordancia entre NIPT el cariotipo para detección embarazos alto riesgo dichas anomalías Materiales métodos. Estudio piloto prospectivo realizado septiembre 2019 diciembre 2020 20 pacientes...
We have developed a new method for non-invasive prenatal testing (NIPT) of paternally inherited fetal mutants for β-thalassemia (β-thal). Specially designed primer-introduced restriction analysis-polymerase chain reaction (PIRA-PCR) were used to detect four major mutations [IVS-II-654, HBB: c.316-197C > T; codon 17 (A > T), HBB: c.52A > T; -28 (A > G), HBB: c.-78A > G and codons 41/42 (-TTCT), ...
OBJECTIVE To validate an updated version (Version 2) of a single-nucleotide polymorphism (SNP)-based noninvasive prenatal test (NIPT) and to determine the likelihood of success when testing for fetal aneuploidies following a redraw. METHODS Version 2 was analytically validated using 587 plasma samples with known genotype (184 trisomy 21, 37 trisomy 18, 15 trisomy 13, 9 monosomy X, 4 triploidy...
OBJECTIVES To determine the underlying biological basis for noninvasive prenatal testing (NIPT) results of multiple aneuploidies or autosomal monosomies. METHODS Retrospective analysis of 113,415 tests to determine the study cohort, consisting of 138 (0.12%) cases reported as a single autosomal monosomy (n = 65), single trisomy with a sex chromosome aneuploidy (n = 36), or with multiple aneup...
