[Mandibulofacial dysostosis]

Area of Science:

• Genetics
• Craniofacial Biology
• Medical Case Reports

Background:

• Mandibulofacial dysostosis, or Treacher-Collins syndrome, is an autosomal dominant disorder.
• It presents with bilateral facial structure hypoplasia, including the zygomatic and mandibular bones.
• Associated anomalies often involve the external and middle ear and ocular features.

Observation:

• The case involves a 19-year-old patient presenting with Treacher-Collins syndrome.
• The patient exhibited characteristic cranio-facial malformations consistent with the syndrome's diagnostic criteria.

Findings:

• The report details the specific cranio-facial malformations observed in the patient.
• The presentation aligns with the known variable expressivity of mandibulofacial dysostosis.

Implications:

• This case contributes to the understanding of Treacher-Collins syndrome's clinical spectrum.
• Highlights the importance of recognizing characteristic features for timely diagnosis and management.
• Further research into genotype-phenotype correlations in mandibulofacial dysostosis is warranted.
