Novel Co‐Occurrence of Trisomy 21 and Heterozygous CFTR Mutation [PDF]
The coexistence of trisomy 21 and cystic fibrosis (CF) is extremely rare, with fewer than 10 reported cases, all involving homozygous CFTR mutations. However, the impact of a heterozygous CFTR mutation in a patient with trisomy 21 remains unexplored.

Objective: We present mosaic trisomy 21 at amniocentesis in a twin pregnancy associated with a favorable fetal outcome, maternal uniparental disomy (UPD) 21 and postnatal decrease of the trisomy 21 cell line.

Improving the Positive Predictive Value of Non-Invasive Prenatal Screening (NIPS). [PDF]
We evaluated performance characteristics of a laboratory-developed, non-invasive prenatal screening (NIPS) assay for fetal aneuploidies. This assay employs massively parallel shotgun sequencing with full automation.

Trisomy 21 and the Brain [PDF]
In fetuses with Down syndrome, neurons fail to show normal dendritic development, yielding a "tree in winter" appearance. This developmental failure is thought to result in mental retardation. In adults with Down syndrome, neuronal loss is dramatic and neurofibrillary and neuritic Abeta plaque pathologies are consistent with Alzheimer disease.

Serum biochemical parameters in pregnant women with and without fetal chromosomal abnornalities
Aim. To analyse the levels of serum beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein A (PAPP-A) in pregnant women without fetal chromosomal abnormalities and with fetal trisomy 21 (Down syndrome) or 18 (Edwards syndrome ...

Prenatal screening tests and prevalence of fetal aneuploidies in a tertiary hospital in Thailand
This study evaluated prenatal screening test performance and the prevalence of common aneuploidies at Siriraj Hospital, Thailand. We collected data from screening tests which are first-trimester test, quadruple test, and noninvasive prenatal tests (NIPT)
