RT Journal Article SR Electronic T1 Norrie disease resulting from a gene deletion: clinical features and DNA studies. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 73 OP 78 DO 10.1136/jmg.25.2.73 VO 25 IS 2 A1 Donnai, D A1 Mountford, R C A1 Read, A P YR 1988 UL http://jmg.bmj.com/content/25/2/73.abstract AB 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.
