De Novo Inverted Duplication Deletion of 4p in a 14-Week-Old Male Fetus Aborted Due to Multiple Anomalies

Abstract

Inverted duplications deletions are rare, complex, and nonrecurrent chromosomal rearrangements associated with a variable phenotype. In this case report, we described the phenotype and genotype of a 14-week-old male fetus, who was aborted after discovery of multiple anomalies (septal cystic hygroma, open abdominal wall, and a nonidentifiable lower limb). At autopsy, fluorescence in situ hybridization and array comparative genomic hybridization identified an inverted duplication with terminal deletion of 4p [46,XY,der(4)del(p16.3)dup(4)(p15.2p16.3)]. Only five genotypically similar cases have been reported, and we hope our case contribution will add meaningful to the body of knowledge.
