Endocardial cushion defect in a patient with Crouzon syndrome carrying a mutation in the fibroblast growth factor receptor (FGFR)-2 gene.

Crouzon syndrome is an autosomal dominant disorder caused by mutation in the fibroblast growth factor receptor (FGFR)-2 gene. Recent findings from animal studies imply a critical role for FGFs in the regulation of cardiac development including cardiac cushion proliferation and valvulogenesis. We report on a 36-year-old woman, who required surgical closure for an atrial septal defect, a clinical feature that has not been previously reported in other patients with Crouzon syndrome. The findings suggest that cardiac investigations are warranted in patients with a diagnosis of Crouzon syndrome.     «
