Performance of non-invasive prenatal testing for trisomies 21 and 18 in twin pregnancies

Molecular Cytogenetics, 2018
Background Cell-free fetal DNA in maternal plasma represents a source of fetal genetic material that can be sampled noninvasively. There are ample studies confirming the accuracy of NIPT in singleton pregnancies, but there is still relatively little ...

Molecular delineation of small supernumerary marker chromosomes using a single nucleotide polymorphism array

Molecular Cytogenetics, 2020
Background Defining the phenotype-genotype correlation of small supernumerary marker chromosomes (sSMCs) remains a challenge in prenatal diagnosis. We karyotyped 20,481 amniotic fluid samples from pregnant women and explored the molecular characteristics
