An RCS-Like Retinal Dystrophy Phenotype in<i>Mer</i>Knockout Mice

Abstract

Ablation of Mer function in mer(kd) mice results in a retinal phenotype almost identical with that of RCS rats. The similarity in phenotypes between the two rodent models suggests that an RPE phagocytic defect is a feature of all types of retinal degeneration caused by loss of function of Mer tyrosine kinase, perhaps including mutations in human MERTK.
