The Phenotype of Early-Onset Retinal Degeneration in Persons with<i>RDH12</i>Mutations

Abstract

Ophthalmic findings in persons with RDH12 mutations suggest that RDH12 loss-of-function results in a characteristic form of early and progressive rod-cone degeneration distinct from that caused by mutations in other LCA genes. From our data, it seems likely that various clinical designations appropriately describe the diagnosis in these persons, including early-onset retinitis pigmentosa, LCA type II, and childhood retinal dystrophy.
