Background: Apert syndrome is a rare form of syndromic craniosynostosis, also known as acrocephalosyndactyly, which is a disorder characterized by a unique set of craniofacial, hand, and foot abnormalities. Diagnosis is made through a genetic analysis, where the mutation of FGFR2, Ser252Trp, and Pro253Arg confirms the diagnosis.
Case presentation: Although craniosynostosis is the most common characteristic in clinical presentation, we present an atypical case of a one-and-a-half-year-old girl with Apert syndrome confirmed by genetic testing but without craniosynostosis.
