We present two consecutive pregnancies with shared ultrasound findings-sloping forehead, micrognathia, ambiguous genitalia, brachycephaly, short extremities, single umbilical artery, choroid plexus cysts, and clenched hands. Subsequent whole exome sequencing identified TRAIP gene variants implicating diagnosis of Seckel syndrome 9 (SCKL9). Prenatal testing in subsequent pregnancy identified one variant. Our case highlights the utility of whole exome sequencing when prenatal ultrasound findings lend suspicion. Molecular confirmation allows for testing strategies in, or prior to, subsequent pregnancies. The finding of a rare, novel missense variant in TRAIP gene further implicates this mutation as having deleterious clinical manifestations.
