Mutations of the peripherin/RDS gene have been reported in autosomal dominant retinitis pigmentosa, pattern macular dystrophy, and retinitis punctata albescens.
We evaluated patients with hereditary retinal diseases featuring subretinal spots (retinitis punctata albescens and fundus albipunctatus) and patients with typical dominant or recessive retinitis pigmentosa for mutations in RDH5.
In this report we studied one sporadic type retinitis punctata albescens patient with the assumption that mutation in the peripherin/RDS gene could contribute to the disease phenotype.
Mutations of the peripherin/RDS gene have been reported in autosomal dominant retinitis pigmentosa, pattern macular dystrophy, and retinitis punctata albescens.
These findings suggest that Usher syndrome type III can be clinically misdiagnosed as either Usher type I or II; that Usher syndrome patients who are profoundly hearing impaired and have normal vestibular function should be tested for USH3 mutations; and that RPA and RPSP can occur as fundoscopic manifestations of pigmentary retinopathy in Usher syndrome.
Identification of a polymorphic missense (G338D) and silent (106V and 121L) mutations within the coding region of the peripherin/RDS gene in a patient with retinitis punctata albescens.
