title: Gorlin syndrome: the PTCH gene links ocular developmental defects and tumour formation.
abstract: OBJECTIVE
  To identify a gene linking microphthalmia with cyst with early onset medulloblastoma.
  
  
  METHODS
  Mutation analysis of the PTCH gene.
  
  
  RESULTS
  A mutation in exon 10 of the PTCH gene was identified, confirming a diagnosis of Gorlin syndrome.
  
  
  CONCLUSIONS
  This is the first genetically identified mutation giving rise to microphthalmia with cyst and provides a valuable link in the eye developmental gene pathway.
