Abstract

PURPOSE:

To determine whether autosomal dominant iris hypoplasia is caused by mutations in the newly described gene for Rieger syndrome (RIEG/PITX2).

METHOD:

Mutation screening and sequence analysis was performed in a single family.

RESULTS:

A novel mutation in the RIEG/PITX2 gene was found in all affected but no unaffected individuals. This mutation would be expected to result in an arginine to tryptophan amino acid change in the homeodomain of solurshin, the RIEG/ITX2 gene product.

CONCLUSION:

Autosomal dominant iris hypoplasia is caused by a defect in the same gene that is defective in many cases of Rieger syndrome.
