Uncultured Amniocytes Enable Rapid and Clinically Informative Prenatal RNA Sequencing for Genetic Diagnosis. [PDF]
RNA sequencing (RNA-seq) provides transcript-level evidence for interpreting variants of uncertain significance in monogenic disorders, but its prenatal application is limited by sample availability and processing time. This study evaluated uncultured amniocytes as a practical substrate for prenatal RNA-seq.

Trisomy 7 mosaicism at amniocentesis: Interphase FISH, QF-PCR, and aCGH analyses on uncultured amniocytes for rapid distinguishing of true mosaicism from pseudomosaicism [PDF]
Objective: To present prenatal diagnosis of true trisomy 7 mosaicism. Materials, Methods and Results: A 36-year-old woman underwent amniocentesis at 18 weeks of gestation. Amniocentesis revealed a karyotype of 47,XY,+7[20]/46,XY[9].
