Abstract
Warsaw Breakage Syndrome (WABS) is a rare autosomal recessive cohesinopathy characterized by growth retardation and congenital anomalies. This report aims to highlight the prenatal diagnosis of WABS through ultrasound findings and genetic testing. We report a case of prenatal diagnosis of WABS in a 24-week gestation fetus exhibiting microcephaly, delayed sulcation, short corpus callosum, cerebellar vermis hypoplasia and intrahepatic portal-systemic shunts. The couple had a history of a prior pregnancy termination due to severe intrauterine growth restriction and cerebral malformations. Whole exome sequencing revealed compound heterozygous pathogenic variants [NM_030653.4:c.1403dupT, p.(Ser469Valfs*32) and c.1672C>T, p.(Arg558*)] in the DDX11 gene, consistent with WABS. The same pathogenic variants were identified in the prior terminated fetus upon subsequent analysis. Postmortem examination of the proband confirmed the prenatal ultrasound findings. This case expands the understanding of the prenatal phenotypic spectrum of WABS by identifying specific cerebral and extracerebral anomalies associated with pathogenic variants in the DDX11 gene. Incorporating advanced genetic diagnostics like whole exome sequencing into prenatal care provides valuable information for genetic counseling and management of rare genetic disorders.
