We describe a 37-week gestation female infant who was born with a terminal 2q deletion. Both of her parents had normal chromosomes. This infant had multiple anomalies, including hypertelorism, short palpebral fissures, microphthalmia, cleft lip/cleft palate, and abnormal ears. Autopsy documented Dandy-Walker malformation with severe hydrocephalus, aortopulmonary window, secundum atrial septal defect, duodenal atresia, incomplete rotation of the bowel, gonadal dysgenesis, uterus didelphys, and musculoskeletal defects. Compared with the other 6 children with 2q terminal deletion documented in the literature, this patient is the most severely affected. This patient is also the only one documented to have died and undergone autopsy examination. The findings in this case provide more data for the eventual description of a "terminal 2q deletion syndrome" and suggest that some abnormalities, such as gonadal dysgenesis, may be present in living children with this chromosome abnormality.
