Pfeiffer syndrome.

Area of Science:

• Genetics
• Pediatrics
• Medical Genetics

Background:

• Pfeiffer syndrome is a rare autosomal dominant disorder affecting approximately 1 in 100,000 individuals.
• It is characterized by craniosynostosis, broad thumbs and toes, partial syndactyly, and potential complications like hydrocephalus and developmental delay.
• The condition is classified into three subtypes based on phenotypic severity.

Purpose of the Study:

• To provide a comprehensive overview of Pfeiffer syndrome, including its genetic basis, clinical manifestations, diagnostic approaches, and management strategies.
• To highlight the importance of molecular genetic testing in confirming the diagnosis and understanding the underlying mutations in fibroblast growth factor receptor genes (FGFR-1 or FGFR-2).

Main Methods:

• Review of existing literature on Pfeiffer syndrome.
• Description of clinical subtypes and associated phenotypes.
• Discussion of diagnostic methods including prenatal sonography and molecular genetic testing.
• Outline of surgical management approaches.

Main Results:

• Pfeiffer syndrome presents with a spectrum of severity, from mild classic type 1 to more severe types 2 and 3.
• Mutations in FGFR-1 or FGFR-2 genes are the primary cause.
• Prenatal diagnosis is possible through sonography and molecular testing.
• Management involves staged craniosynostosis surgery and midfacial reconstruction.

Conclusions:

• Pfeiffer syndrome requires a multidisciplinary approach for optimal patient outcomes.
• Accurate diagnosis through genetic testing is crucial for guiding treatment.
• Surgical interventions aim to correct skeletal abnormalities and improve function and aesthetics.
