Abstract

We report a rare co-occurrence of intestinal malrotation and Hirschsprung's disease (HSCR) in a male neonate with a large 38.8 Mb interstitial deletion of chromosome 13 extending from q21.31 to q33.1 including the EDNRB gene, who presented with craniofacial dysmorphic features and central nervous system malformations. The loss of EDNRB gene in addition to bilateral hearing loss and HSCR suggested an additional diagnosis of Waardenburg–Shah's syndrome. This case highlights the fact that prior knowledge of this rare association in infants with 13q deletion syndrome would enable early diagnosis and prompt interventions to prevent gastrointestinal complications.
