A Rare Case of Prenatally Diagnosed Pfeiffer Syndrome with Multicystic Kidney.

Abstract

Pfeiffer syndrome is a rare syndromic craniosynostosis characterized by bilateral coronal craniosynostosis, midface hypoplasia, beaked nasal tip, broad and medially deviated thumbs and great toes. It is caused by mutations affecting the fibroblast growth factor receptors type 1 or 2 (FGFR1 or FGFR2), with autosomal dominant inheritance. It displays substantial clinical and genetic heterogeneity. The disorder is usually detected in the neonatal period, and very few prenatally diagnosed cases have been reported.
