A Rare Finding of Mosaic 45,XX,der(13;21)(q10;q10)[15]/46,XX,r(13)(p11.2q33) Following Abnormal Prenatal Chromosomal Microarray Testing [PDF]
Mosaicism for both a ring chromosome and Robertsonian translocation is a rarely reported cytogenetic phenomenon. We describe a case referred for testing following abnormal noninvasive prenatal screening for trisomy 13.

Chromosomal and genetic anomalies in fetuses with nuchal translucency between 3.0 and 3.4 mm: A systematic review and meta-analysis. [PDF]
Fetuses with a nuchal translucency between 3.0 and 3.4 mm showed a high rate of chromosomal anomalies and copy number variants, most of which could potentially be detected through cell‐free DNA. Abstract Introduction To report the prevalence of chromosomal anomalies in fetuses with a nuchal translucency (NT) between 3.0 and 3.4 mm and to assess the ...

Genetic evaluation and pregnancy outcome of fetuses with digestive system malformations: an eight-year single-center retrospective study [PDF]
BackgroundLimited reports have investigated the genetic etiology of fetuses with digestive system malformations (DSMs). Our initial aim was to describe supplement data of fetal DSMs and further elucidate the genotype-phenotype correlations in fetuses ...

Clinical and Cytogenomic Characterization of Three Patients With Distal 1q43q44 Deletion: Twin Sisters With a de novo Deletion and a Patient With der(1)t(1;21)(q43;q22.3)mat. [PDF]
Distal 1q43q44 deletions lead to a consistent neurodevelopmental phenotype characterized by microcephaly, corpus callosum abnormalities, and developmental delay. Despite differences in genomic architecture, overlapping deletions affecting dosage‐sensitive genes such as AKT3, HNRNPU, and ZBTB18 define the core phenotype.

Prenatal exome sequencing of fetuses with central nervous system anomalies based on prenatal ultrasound and magnetic resonance imaging diagnosis: A retrospective cohort study with a systematic review and meta-analysis. [PDF]
Prenatal exome sequencing significantly improves diagnostic yield over chromosomal microarray analysis for fetal CNS abnormalities, with a diagnostic yield of 16% in our cohort and 27% in the meta‐analysis. Diagnostic yields vary across different phenotypes. Abstract Introduction Fetal central nervous system (CNS) abnormalities have diverse etiologies,
