Deletion of 8p23.1 with features of Cornelia de Lange syndrome and congenital diaphragmatic hernia and a review of deletions of 8p23.1 to 8pter? A further locus for Cornelia de Lange syndrome.
Cornelia de Lange syndrome (CdLS) is characterized by facial dysmorphism; hirsutism; internal organ anomalies, including diaphragmatic hernia, and limb defects. While causative mutations in three genes have been identified the etiology of a significant number of cases remains unknown. We report on a child with an 8p23.1 deletion with features of CdLS and congenital diaphragmatic hernia. We review cases with cytogenetic anomalies involving 8p23.1, discuss a potential relationship between 8p23.1 deletions and CdLS and suggest a novel candidate gene for CdLS-Tankyrase 1.
