Abstract

Cytomegalovirus (CMV) intrauterine infection is a risk factor underlying Fetal Growth Restriction (FGR). Maternal secondary infection is of lower vertical transmission rate compared to primary infection during pregnancy. Whole Genome Sequencing (WGS) detects nearly all types of genomic variants and is increasingly applied to prenatal diagnosis. In the present study, we describe a growth-restricted fetus, of which CMV intrauterine infection was initially not suspected due to prior maternal immunity. WGS of DNA extracted from amniotic-fluid cells incidentally detected the presence of CMV. Our experience highlights incorporating pathogen analysis in WGS is of clinical value.
