No approved commercial gene therapy company yet for albinism. Target Population Patients with Oculocutaneous Albinism Type 1 (OCA1) caused by mutations in the TYR (tyrosinase) gene, resulting in little or no melanin production in skin, hair, and eyes. Issue OCA1 is a rare genetic disorder causing severe hypopigmentation and major visual impairment, including foveal hypoplasia, nystagmus, reduced visual acuity, and photophobia. There are no disease-modifying approved therapies, only supportive care (vision correction, UV protection). Study The therapeutic approach is based on AAV (adeno-associated virus) gene therapy, designed to deliver a functional TYR gene to retinal pigment epithelium (RPE) cells. The goal is to restore tyrosinase enzyme activity and enable melanin production in ocular tissues. Research is currently focused on preclinical studies (cell culture and animal models) assessing delivery efficiency, safety, and retinal targeting. Some NIH/NEI-supported programs are advancing toward translational readiness, but human interventional data remains extremely limited or not yet established in published Phase 1 trial results. Outcome Confirmed outcomes are limited to preclinical evidence only: The approach demonstrated feasibility of AAV-mediated gene delivery to ocular tissues in experimental models. It is a proof-of-concept that gene delivery may influence retinal pigment epithelium development. However, no approved therapy exists. Overall, the therapy remains early-stage translational research, but is considered the most advanced disease-modifying approach under investigation for OCA1. Share this article
