A prenatally diagnosed Klinefelter syndrome case of 46,XX/47,XXY mosaicism with partial deletion of Y chromosome

open access: yesTaiwanese Journal of Obstetrics & Gynecology
Objective: Herein, we report the first case of 46,XX/47,XXY mosaicism with a partially deleted Y chromosome. Case report: Chorionic villus sampling (CVS; G-banding) was performed due to increased nuchal translucency; the results showed a 46,XX karyotype.

Prenatally Diagnosed 7q11.23 Copy Number Variations: A Retrospective Case Series

open access: yesMolecular Genetics &Genomic Medicine, Volume 14, Issue 1, January 2026.
Prenatal 7q11.23 CNVs exhibit 100% ultrasound anomalies in deletions (cardiovascular defects, growth restriction) and 50% in duplications. Inherited CNVs (50% deletions, 43% duplications) correlate with milder outcomes, while de novo variants drive high TOP rates (76.5%), emphasizing genomic testing and parental studies for precise counseling.

Prenatal Exome Sequencing Analysis in Fetuses With Structural Anomalies: A Multicenter Prospective Cohort Study With Practical Implications

open access: yesPrenatal Diagnosis, Volume 46, Issue 1, Page 46-55, January 2026.
ABSTRACT Objective To evaluate the diagnostic value of prenatal exome sequencing (ES) integrated with copy number variant (CNV) and single nucleotide variant (SNV) analysis (ES‐CNV/SNV) in fetuses with structural anomalies following negative chromosomal microarray analysis (CMA) and karyotyping, and to delineate the practical challenges encountered ...

Banning Abortion in Cases of Down Syndrome: Important Lessons for Advances in Genetic Diagnosis [PDF]

open access: yes, 2018
In December 2017, Ohio passed into law legislation that prohibited physicians from performing abortions if the pregnant woman’s decision was influenced by her belief that the fetus has Down syndrome.

Insights Into Congenital Lymphatic Anomalies Underlying Fetal Effusions

open access: yesPrenatal Diagnosis, Volume 46, Issue 1, Page 3-11, January 2026.
ABSTRACT Objective We describe a series of pregnancies with autosomal dominant lymphedema and generalized lymphatic dysplasia in the fetus diagnosed with prenatal exome or genome sequencing. We focus on specific syndromes, fetal features, and parental symptoms to deepen our understanding of congenital lymphatic anomalies.

Placental chorangiomas: Diagnostic challenges and contemporary approaches to fetal care

open access: yesPregnancy, Volume 2, Issue 1, January 2026.
Abstract Placental chorangiomas are the most common benign tumors of the placenta. Although most are small and asymptomatic lesions, giant chorangiomas are associated with an increased risk of adverse maternal and fetal outcomes. Therefore, in those affected by giant placental chorangioma, early diagnosis and intensive fetal monitoring are indicated to

Whole‐genome paternal uniparental disomy identified through prenatal single‐nucleotide polymorphism‐based cell‐free DNA screening

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 1, Page 73-78, January 2026.
ABSTRACT Objective Prenatal single‐nucleotide polymorphism (SNP)‐based cell‐free DNA (cfDNA) screening can identify genome‐wide paternal uniparental disomy (GW‐UPDpat), including cases with complete hydatidiform mole with a coexisting fetus (CHMCF), those with placental mesenchymal dysplasia (PMD) and those with a mosaic/chimeric GW‐UPDpat syndrome ...
