De novo translocation interrupting the transcription unit of SATB2 gene has been associated with cleft palate only (CPO). We tested for the presence of the copy number of SATB2 gene in a sample of 92 patients with CPO using a quantitative real-time PCR approach. In one patient (1%, 95% CI = 0.2%–6%), a 19 Mb de novo deletion encompassing the SATB2 gene was detected. These results suggest that SATB2 gene deletions do not play an important role in the etiology of cleft palate.
