Evolving Features of RASopathies Among Pregnancies With Abnormal Fetal Fluid Collections

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective We aimed to characterize the fetal features across gestation and describe genotype‐phenotype correlations for pregnancies with fetal RASopathies that were more severely affected as they presented with at least one abnormal fluid collection.

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 ...
