Abstract
Exomphalos may be associated with chromosomal abnormalities and syndromes. Severe exomphalos (herniation of liver, midgut and spleen) associated with increased nuchal translucency was seen at first trimester screening test. Karyotype by chorionic villus sampling showed normal male fetus. Follow up scan at 16 and 18 weeks of gestation confirmed the severe exomphalos and detected micrognathia and tetralogy of Fallot. Array comparative genomic hybridization (a-CGH) further demonstrated a 408kb 15q11.2 microduplication, with the father-to-be as healthy carrier. This is the first case of an association between 15q11.2 micorduplication and fetal sonographic anomalies. Genetic counseling for estimation of recurrent risk of congenital anomalies is discussed.
