Abstract

Deletions within 11q12.3-11q13.1 are very rare and to date only two cases have been described in the literature. In this study we describe a 23-year-old male patient with intellectual disability, behavioral problems, dysmorphic features, dysphagia, gastroesophageal reflux and skeletal abnormalities. Cornelia de Lange syndrome (CdLS, OMIM #122470; #300590; #610759; #300882; #614701) was suggested as a differential diagnosis in childhood although he lacked some of the features typical for this disorder. He does not have a mutation in any of the five known CdLS genes (NIPBL, SMC1A, SMC3, HDAC8, RAD21), but a 1.6Mb deletion at chromosome region 11q12.3-11q13.1 was detected by chromosome microarray. The deletion contains several genes including PPP2R5B, which has been associated with intellectual disability and overgrowth; NRXN2, which has been associated with intellectual disability and autism spectrum disorder; and CDCA5, which is part of the cohesin pathway, as are all the five known CdLS genes. It is therefore possible that deletion of CDCA5 may account for some of the CdLS like features of the present case.
