Abstract

We report a male infant with 22q11.2 deletion syndrome and very severe multi-sutural craniosynostosis associated with increased intracranial pressure, marked displacement of brain structures, and extensive erosion of the skull. While uni- or bi-sultural craniosynostosis is a recognized (though relatively uncommon) feature of 22q11 deletion syndrome, a severe multi-sutural presentation of this nature has never been reported. SNP Microarray was otherwise normal and the patient did not have common mutations in FGFR2, FGFR3, or TWIST associated with craniosynostosis. While markedly variable expressivity is an acknowledged feature of deletion 22q11 syndrome, herein we also consider and discuss the possibility that this infant may have been additionally affected with an undiagnosed single gene disorder. © 2012 Wiley Periodicals, Inc.
