Uncovering the Genetic Landscape of Spinal Dysraphism: A Retrospective Analysis of 150 Fetal Cases

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Spinal dysraphism (SD) results from incomplete neural tube closure and encompasses a heterogeneous group of congenital anomalies with genetic and environmental etiologies. Although genetic contributions are recognized, causative variants remain insufficiently defined, and the clinical implications of extended genetic testing on ...

Clinical Utility of Nuchal Translucency Measurement in First‐Trimester Ultrasound Screening in a Setting With First‐Tier NIPT for Aneuploidy Screening

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To investigate the additional clinical value of nuchal translucency (NT) measurement at the first‐trimester anomaly scan (FTAS) in a setting with first‐tier non‐invasive prenatal testing (NIPT). Method This nationwide prospective cohort study, part of the IMITAS study on FTAS implementation, included all pregnancies with increased NT

Moderate Diagnostic Yield of Exome Sequencing in Fetal Growth Restriction: Retrospective Insights

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To determine whether invasive genetic testing should be systematically proposed in cases of FGR. Methods Descriptive retrospective study of 159 FGR cases (defined by an estimated fetal growth < 3rd percentile, regardless of Doppler findings) managed at the Toulouse Fetal Medicine Center (TFMC) during 2022–2023.

Gene List Selection Matters: Missed Diagnoses in Prenatal Exome Sequencing—PanelApp R21 and HPO‐Driven Versus OMIM‐Based Gene Lists

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To evaluate whether the causative variants found upon clinical exome sequencing in fetuses affected with selected structural anomalies would also be detected if PanelApp‐R21 or Human Phenotype Ontology (HPO)‐driven gene selection terms were applied instead.

QUANTITATIVE KARYOTYPE OF DIPLODON CHILENSIS (GRAY 1828) (BIVALVIA:HYRIIDAE) CARIOTIPO CUANTITATIVO DE DIPLODON CHILENSIS (GRAY 1828) (BIVALVIA:HYRIIDAE)

Gayana, 2000
The karyotype of a freshwater population of Diplodon chilensis located in La Poza area of the Villarrica Lake (39º18'S; 72º05'W), Southern Chile, was studied. The chromosomes were obtained by squash of cleaving embryos, previously treated with colchicine

Diagnosed After Birth—But Detectable Before? A Cohort Study of Prenatal Testing Potential

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To evaluate the yield of prenatal genetic testing in infants with a confirmed genetic diagnosis. Methods We retrospectively reviewed records of infants with a genetic diagnosis who were evaluated using a standardized genetic consult and testing approach. The predicted yield of various prenatal genetic sceening and diagnostic tools in

Diagnostic Yield of Sequencing for Prenatal Diagnosis of Fetal Structural Anomalies: An Updated Systematic Review

Prenatal Diagnosis, EarlyView.
ABSTRACT The clinical utility of sequencing in prenatal diagnosis is known, but diagnostic yield varies widely depending on clinical indication. Here we update an earlier systematic review reporting the diagnostic yield of prenatal sequencing in structurally abnormal fetuses, with particular focus on factors affecting diagnostic yield.

The Clinical Utility of Sequence‐Based Genetic Testing for Fetal Edema Following Non‐Diagnostic Microarray Results: A Population‐Based Cohort Study

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective Ultrasound findings of fetal edema may provide early evidence of a genetic disorder. Our objective was to evaluate the frequency and diagnostic yield of sequencing in a selected population after a non‐diagnostic microarray result for fetal edema.

Prenatal Tympanic Ring Anomaly Without Microtia: A Subtle Clue Toward Severe Early‐Onset Monogenic Disorders

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To investigate the genetic etiologies and clinical significance of fetal tympanic ring abnormalities detected during second‐trimester ultrasound in the absence of microtia. Method Between November 2019 and June 2024, we examined the fetal tympanic rings of 10,277 unselected pregnant women during the 20–22 weeks of morphology ...
