AIMS: To identify the phenotypic variations in 6 related individuals affected by a novel mutation in the retinal degeneration slow/peripherin gene. METHODS: Ten family members underwent ophthalmologic assessment with slit-lamp biomicroscopy, dilated fundus examination, fundus photography, autofluorescence imaging and electrophysiological tests. Genomic DNA was extracted from blood samples of all family members (n = 15) using the standard salting-out procedure. RESULTS: The novel C165R mutation was identified in 8 individuals. Of these 8 patients, only 6 gave consent to the clinical study. They had a retinal disease characterized by an adulthood onset of symptoms, and their best corrected visual acuity was between 20/50 and 20/20. Fundus examination showed that 3 patients had typical fundus flavimaculatus: 1 had butterfly-shaped pattern dystrophy and 2 had incipient retinal changes. CONCLUSION: We identified a novel mutation of the retinal degeneration slow/peripherin gene in a family affected by different patterns of retinal dystrophy. This is the first report of an association of fundus flavimaculatus with butterfly-shaped pattern dystrophy. (c) 2007 S. Karger AG, Basel.
