Craniosynostosis in a patient with a de novo 15q15-q22 deletion

interstitial deletions involving the chromosomal band 15q15 are very rare. A total of five cases were previously reported. Here another case of a 15q15.2-q22.2 deletion is reported, presenting with severe craniosynostosis of coronary, metopic, and Sagittal Sutures. The chromosome 15 with the 17.7-Mb deletion was of the paternal origin. A critical region for craniosynostosis may be located at the 734-kb segment at 15q15.2. Interestingly, the entire FBN1 gene was deleted in this patient. (C) 2008 Wiley-Liss, Inc.
