Fetal Brain Abnormalities in Trisomy 21 and Associated Neurodevelopmental Outcome: Key Factors to Identify Differences in Neurodevelopmental Outcome?

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Trisomy 21 (T21) is associated with various neurological impairments. However, the mechanisms of fetal brain development in T21 and their impact on neurodevelopmental outcomes remain unclear, limiting prenatal counseling. Therefore, this study aims to assess neuropathological changes in fetuses with T21 and the associated ...

Genetic Investigation in Fetal Growth Restriction: An Integrated Approach for Clinical Practice

Prenatal Diagnosis, EarlyView.
ABSTRACT International guidelines recommend genetic testing when fetal growth restriction (FGR) accompanies structural anomalies, but recommendations for apparently isolated FGR remain variable, particularly regarding gestational age thresholds and the role of exome sequencing (ES). Interpretation is difficult because studies define FGR inconsistently,

Diagnostic Yield of Sequencing in Prenatal Agenesis of the Corpus Callosum in a Well‐Phenotyped International Cohort

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To evaluate the incremental diagnostic yield of sequencing in a large, well‐phenotyped international cohort of fetuses with prenatally diagnosed agenesis of the corpus callosum (ACC) and to identify associated genes and variants. Methods Retrospective multicenter cohort study of fetuses with a prenatal diagnosis of ACC undergoing ...

A rare case of NIPT discrepancy caused by the placental mosaicism of three different karyotypes, 47,XXX, 47,XX,+21, and 48,XXX,+21

Molecular Genetics & Genomic Medicine, 2020
Background Placental mosaicism is one of the major reasons for noninvasive prenatal testing (NIPT) discrepancy. Herein, we discovered a rare case of placenta with complex karyotypes that caused false‐positive and false‐negative results in noninvasive ...

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...
