Antisense oligonucleotide therapy for proline-23-histidine autosomal dominant retinitis pigmentosa

Abstract

Purpose of reviewTo discuss antisense oligonucleotide (ASON) therapy for autosomal dominant retinitis pigmentosa (adRP) caused by the proline-23-histidine (P23H) mutation in the rhodopsin gene. Recent findingsViral and nonviral therapies to treat adRP are currently under investigation. A promising therapeutic option is a nonviral approach using ASONs. This form of genetic therapy has demonstrated a dose-dependent and highly selective reduction of P23H mutant rhodopsin mRNA in animal models, and it is currently being investigated as a human phase 1/2 clinical trial.
