Background: Mowat Wilson syndrome was probably first described in a 2.5-year old boy by Lurie et al (1994) from Baltimore School of Medicine.

The syndrome is commonly associated with Hirschsprung disease or chronic constipation. In the hands of experts, the distinctive facial features allow the clinical diagnosis of Mowat-Wilson syndrome.
