Abstract
Objective To diagnose and explore the genetic aetiology of Simpson–Golabi–Behmel
syndrome type 1 (SGBS1) in two male fetuses. Methods Prenatal ultrasound scans and further genetic analysis using karyotype
analysis, chromosomal microarray analysis, whole exome sequencing (WES) and
Sanger sequencing were conducted. Results Prenatal ultrasound scans of two fetuses showed multiple congenital anomalies
and hydramnios. Subsequent to termination of the pregnancies, a novel
nonsense variant (c.892G>T, p.E298*) in the glypican 3
(GPC3) gene of the two fetuses was identified by WES
and further confirmed by Sanger sequencing. The two fetuses were diagnosed
with SGBS1. The mother was heterozygous for the c.892G>T variant. Conclusion This study describes the prenatal sonographic features of SGBS1, emphasizes
the role of WES in the diagnosis of SGBS1 and expands the known mutation
spectrum of the GPC3 gene.
