Apert syndrome

Area of Science:

• Medical Genetics
• Pediatrics
• Developmental Biology

Background:

• Apert syndrome is a rare genetic disorder characterized by premature fusion of skull sutures (craniosynostosis) and fusion of fingers and toes (syndactyly).
• It is typically inherited in an autosomal dominant pattern, but spontaneous new mutations can occur.
• Early diagnosis and management are crucial for improving patient outcomes.

Observation:

• A 5-month-old male infant presented with clinical features consistent with Apert syndrome, including acrocephaly and syndactyly of hands and feet.
• Diagnostic confirmation was achieved through skull radiography and ultrasonography.
• The patient was the third child born to unaffected parents, suggesting a de novo mutation.

Findings:

• The case report details the diagnosis of Apert syndrome in an infant with no family history of the condition.
• Skull roentgenography and ultrasonography supported the clinical diagnosis of craniosynostosis and syndactyly.
• The absence of affected relatives in the family history points towards a new genetic mutation causing Apert syndrome in this patient.

Implications:

• This case underscores the importance of recognizing the phenotype of Apert syndrome for timely diagnosis.
• Management involved symptomatic treatment, including acetazolamide for hydrocephalus, vitamin supplementation, and physical therapy.
• Genetic counseling was provided to the parents regarding the recurrence risk and the nature of de novo mutations.
