Abstract

Objective: This study aims to elucidate two distinct fetal ultrasound features associated with aberrant brain sulcus formation as potential prenatal markers for Sotos syndrome caused by mutations in the NSD1 gene.

Method: This retrospective study investigated three fetuses across two pregnancies, including a pair of monochorionic diamniotic twins, all diagnosed with Sotos syndrome via whole exome sequencing (WES). Comprehensive clinical and laboratory data were collected and analyzed. Each fetus underwent a series of specialized neurosonographic assessments to evaluate the development of the cerebral cortex.

Results: All three fetuses exhibited aberrant brain sulcus formation characterized by Sylvian fissure (SF) abnormalities and shallow parietooccipital sulcus (POS). WES revealed the presence of two de novo NSD1 variants in these fetuses.

Conclusions: Fetal aberrant brain sulcus formation may represent a distinctive ultrasound feature indicative of Sotos syndrome, thereby offering additional diagnostic insights for the identification of this condition.

期刊介绍： Prenatal Diagnosis welcomes submissions in all aspects of prenatal diagnosis with a particular focus on areas in which molecular biology and genetics interface with prenatal care and therapy, encompassing: all aspects of fetal imaging, including sonography and magnetic resonance imaging; prenatal cytogenetics, including molecular studies and array CGH; prenatal screening studies; fetal cells and cell-free nucleic acids in maternal blood and other fluids; preimplantation genetic diagnosis (PGD); prenatal diagnosis of single gene disorders, including metabolic disorders; fetal therapy; fetal and placental development and pathology; development and evaluation of laboratory services for prenatal diagnosis; psychosocial, legal, ethical and economic aspects of prenatal diagnosis; prenatal genetic counseling
