Norrie disease resulting from a gene deletion: Clinical features and DNA studies

Abstract

We describe a family in which two boys with Norrie disease have a deletion of the DXS7 locus. The deletion does not extend as far distally as the OTC or DXS84 loci. A full clinical description of the patients is given to help establish the range of manifestations of Norrie disease. There is no evidence of any other X linked disease in our patients.
