[Pathogenic genes and clinical therapeutic strategies for Treacher Collins syndrome]

Area of Science:

• Genetics
• Developmental Biology
• Medical Science

Background:

• Treacher Collins syndrome is a congenital craniofacial malformation.
• It primarily follows an autosomal dominant inheritance pattern.
• The condition involves impaired ribosome biosynthesis and reduced neural crest cell migration.

Purpose of the Study:

• To review research on Treacher Collins syndrome.
• Focus on major pathogenic genes, pathogenesis, and phenotypic characteristics.
• Discuss prevention and treatment strategies.

Main Methods:

• Literature review of scientific research.
• Analysis of genetic, pathogenic, and phenotypic data.
• Synthesis of information on syndrome management.

Main Results:

• Identified key genes: treacle ribosome biogenesis factor 1 (tcof1), RNA polymerase Ⅰ and Ⅲ subunit C (polr1c), and RNA polymerase Ⅰ and Ⅲ subunit D (polr1d).
• Elucidated the mechanism involving blocked ribosome biosynthesis and decreased neural crest cell migration.
• Detailed the resulting first and second branchial arch dysplasia.

Conclusions:

• Understanding the genetic basis and pathogenesis is crucial for Treacher Collins syndrome.
• Further research into prevention and treatment is warranted.
• Comprehensive review provides a foundation for clinical management and future studies.
