  • Title: [Congenital hypertrophy of retinal pigment epithelium: a marker in familial adenomatous polyposis].
    Author: Szwarcberg J, Limacher JM, Fricker JP, Flament J.

    Abstract:
    PURPOSE: Familial adenomatous polyposis (FAP) is an inherited autosomal dominant disorder with marked propensity for malignant transformation. The potential for congenital hypertrophy of retinal pigment epithelium (CHRPE) as a phenotypic marker for this disease is recognized. MATERIAL AND METHODS: We report our investigations in 11 families with familial adenomatous polyposis. CHRPE characteristics were described and the relations between genotype and phenotype and those between CHRPE and severity of FAP are discussed. DISCUSSION: All members of the family should undergo retinal examination at the earliest age possible. The results give an indication of the severity of the intestinal disease and allow an approximate localization of the mutation in the coding sequence, leading to a more rapid genetic analysis.
