Ventriculomegaly(VM)is a common fetal ultrasound abnormality in prenatal screening,with an incidence of about 1％,and is closely related to the intellectual and psychomotor development of children,which can be evaluated by prenatal ultrasound or MRI that can assess its size and morphology.VM can be caused by central nervous system malformations,chromosomal aberrations,gene mutations,genetic syndromes and potential fetal anomalies,with genetics etiology accounting for a large portion of the cases and has become a concern for many families.This review combs genetic advances in fetal VM,including the genetics etiology and its associated molecular mechanisms,as well as the diagnosis and identification of genetic etiologies.
