Confined placental mosaicism of trisomy 6 detected through genome‐wide NIPT was associated with placental abruption

Clinical Case Reports, 2021
Confined placental mosaicism (CPM) leads to discordant noninvasive prenatal testing (NIPT) results. We describe a very rare case of CPM of trisomy 6 detected through genome‐wide NIPT. This case was associated with placental abruption, which might suggest

A capture methyl-seq protocol with improved efficiency and cost-effectiveness using pre-pooling and enzymatic conversion

BMC Research Notes, 2023
Objective The opportunities for sequencing-based methylome analysis of clinical samples are increasing. To reduce its cost and the amount of genomic DNA required for library preparation, we aimed to establish a capture methyl-seq protocol, which adopts ...

Improved library preparation protocols for amplicon sequencing-based noninvasive fetal genotyping for RHD-positive D antigen-negative alleles

BMC Research Notes, 2021
Objective We aimed to simplify our fetal RHD genotyping protocol by changing the method to attach Illumina’s sequencing adaptors to PCR products from the ligation-based method to a PCR-based method, and to improve its reliability and robustness by ...
