Gorlin syndrome: the PTCH gene links ocular developmental defects and tumour formation

Br J Ophthalmol. 2005 Aug;89(8):988-91. doi: 10.1136/bjo.2004.061390.

Abstract

Aim: 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.
