Atypical presentation of a newborn with Apert syndrome

Apert syndrome is a rare syndrome characterized by a consistent phenotype including bilateral coronal suture synostosis with an enlarged anterior fontanel, midface hypoplasia, and complex symmetric syndactyly of hands and feet. We present a boy with Apert syndrome caused by the pathogenic c.755C > G p.Ser252Trp mutation in the FGFR2 gene with atypical characteristics, including premature fusion of the metopic suture with a small anterior fontanel, hypotelorism, and a massive posterior fontanel. Directly after birth, he showed papilledema, epilepsy, and central apneas. We present a newborn with Apert syndrome with atypical craniofacial presentation.
