Urban-Rogers-Meyer Syndrome

Urban-Rogers-Meyer syndrome is a rare genetic disorder characterized by distinctive craniofacial features, developmental delays, and multiple congenital anomalies. First described by Urban, Rogers, and Meyer, this syndrome represents a complex developmental disorder with multisystem involvement.

Key Points

• Classification: Rare genetic developmental disorder
• Inheritance: Autosomal dominant with variable expressivity
• Prevalence: Extremely rare, fewer than 100 reported cases
• Age of Presentation: Usually apparent at birth or early infancy
• Impact: Affects multiple organ systems with varying severity

Genetic Basis and Inheritance

• Molecular Genetics:
  • Gene mutations affecting developmental pathways
  • Complex interactions with developmental regulators
  • Variable penetrance and expressivity
  • Potential genetic modifiers
• Inheritance Pattern:
  • Autosomal dominant transmission
  • De novo mutations common
  • Family history may be negative
  • Genetic counseling implications
• Genetic Testing:
  • Next-generation sequencing
  • Whole-exome sequencing
  • Array CGH analysis
  • Family member screening
