The Gardner syndrome. Significance of ocular features

Abstract

Gardner syndrome is a dominantly inherited familial cancer syndrome characterized by intestinal polyposis, bony hamartomata, and various soft tissue tumors. The risk of malignancy during adult life is essentially 100%, but as yet no phenotypic marker nor biochemical or serological linkage have been useful to identify the presence of the gene in early life. We studied three families in which multiple and bilateral patches of congenital hypertrophy of the retinal pigment epithelium are related uniquely to other phenotypic features of the Gardner gene. This readily identifiable characteristic may be useful to identify early in life individuals at risk for malignancy. We also suggest that the Gardner syndrome may be genetically heterogeneous.
