4.5 Mb microdeletion in chromosome band 2q33.1 associated with learning disability and cleft palate.

We report a 4.5 Mb deletion of 2q33.1 in an individual with developmental delay and cleft palate. There have been various previous reports of deletions of 2q3, all with varying breakpoints and all larger than the current case. Whilst there is some variation in the phenotypes of patients with 2q3 deletions all share a commonly deleted region within 2q33.1 which includes SATB2, a gene previously shown to be associated with cleft palate. The phenotypic features of our patient are milder than those reported so far.
