Prenatal Lethal Diagnosis of 8p23.1 Duplication Syndrome Associated with Omphalocele and Encephalocele

Despite increased prenatal and postnatal use of array comparative genomic hybridization (aCGH), isolated 8p23.1 duplication remains rare and has been associated with a widely variable phenotype. Here, we report an isolated 8p23.1 duplication in a fetus with an omphalocele and encephalocele that were...

Description
Summary:Despite increased prenatal and postnatal use of array comparative genomic hybridization (aCGH), isolated 8p23.1 duplication remains rare and has been associated with a widely variable phenotype. Here, we report an isolated 8p23.1 duplication in a fetus with an omphalocele and encephalocele that were incompatible with life. Prenatal aCGH demonstrated a 3.75 Mb de novo duplication of 8p23.1. This region encompassed 54 genes, 21 of which are described in OMIM, including SOX7 and GATA4. The summarized case demonstrates phenotypic features not previously described in 8p23.1 duplication syndrome and is reported in order to enhance understanding of the phenotypic variation.
