Case Report: How whole-genome sequencing-based cell-free DNA prenatal testing can help identify a marker mhromosome

Frontiers in Genetics, 2022
A supernumerary marker chromosome (SMC) is a structurally abnormal chromosome that cannot be characterized by conventional banding cytogenetics. Marker chromosomes are present in 0.075% of prenatal cases.

To guide or not to guide: A randomized study on the use of needle guide for chorionic villus sampling training. [PDF]

Acta Obstet Gynecol Scand
In this randomized study, novice performance improved when a needle guide was used during chorionic villus sampling (CVS) training. Incorporating needle guides into training may help ensure safer practice, particularly as clinical opportunities for skill development decrease. Abstract Introduction Chorionic villus sampling (CVS) is an invasive prenatal

Relevance of Invasive Testing in Era of Non-Invasive Testing for Prenatal Chromosomal Abnormalities

Gynecology Obstetrics & Reproductive Medicine, 2022
Prenatal screening for chromosomal abnormalities has two components i.e. prenatal screening (maternal serum screening and cell-free fetal DNA screening) and prenatal diagnosis (chorionic villus sampling, amniocentesis, and cordocentesis).

Case report: Prenatal diagnosis of rare chromosome mosaicism: discordant results between chorionic villi and amniotic fluid samples

Frontiers in Genetics, 2023
Objective: We described a unique case of near-negative chromosome mosaicism in chorionic villi but complete monosomy X in amniotic fluid.Methods: Chorionic villus sampling and amniocentesis were performed separately in the first and second trimesters ...
