Apert syndrome (AS) is clinically characterized by typical facial features and symmetrical syndactyly of the digits. AS is inherited as an autosomal dominant trait. Recently, a fibroblast growth factor receptors 2 (FGFR2) mutation, either C934G or C937G, was identified in exon IIIa. Our report docum

โฆ Synopsis
Apert syndrome is a rare craniosynostosis syndrome with significant bilateral syndactyly of the hands and feet. Usually it is detected by ultrasonography during the third trimester unless there is a family history. We present an interesting sporadic case with features consistent with Apert syndrome detected as early as the first trimester. A first-trimester ultrasound evaluation prior to chorionic villus sampling (CVS) for maternal age 41 was within normal limits except for the suggestion of a 'mitten-like' hand and proximally placed thumb. Mid-trimester ultrasound was not diagnostic; however, following the development of polyhydramnios in the third trimester, the evaluation of the digits and facial features were strongly suggestive of Apert syndrome. Amniocentesis was performed and a molecular diagnosis of Apert syndrome was made and confirmed on cord blood. 1997 by John Wiley & Sons, Ltd.
