Novel codon 15 RHO gene mutation associated with retinitis pigmentosa.


ABSTRACT: Objective:To describe, in a multimodal way, a new RHO gene mutation with lysine-for-asparagine substitution in autosomal dominant retinitis pigmentosa. Methods:Case report. Retrospective data analysis. Results:The mutation is located within codon 15 of exon 1 of the RHO gene. A single base-pair transversion lead to a specific lysine-for-asparagine substitution (Asn15Lys). Hypoacusis, myopia, dyschromatopsis and diffuse retinitis pigmentosa were detected. Detailed multimodal images for the posterior segment are presented. Conclusion:We present a new mutation with a specific substitution that may cause eye disease and which has not been described previously. There is no description of this variant in the genetic databases.
