Identification of a patient with intellectual disability and de novo 3.7Â Mb deletion supports the existence of a novel microdeletion syndrome in 2p14-p15

► We report a 4-year-old boy with a de novo 3.7 Mb deletion of 2p14-p15. ► Comparison with patients reported previously points to a new microdeletion syndrome. ► These deletions are separated from deletions responsible for the 2p15-p16.1 syndrome. ► The 2p14-p15 deletions harbor candidate intellectual disability genes.
