PURPOSE: Choroideremia (CHM) is a progressive X-linked degeneration of three ocular layers (photoreceptors, retinal pigment epithelium, and choroid), with a complex and still largely unclear pathogenesis. To investigate the pathophysiology of CHM, the authors engineered mice with a cell type-specific Chm/Rep1 knockout (KO). METHODS: A mouse line carrying a conditional allele Chm(Flox) was crossed with the transgenic line IRBP-Cre to achieve Chm KO, specifically in the photoreceptor layer, and...Expand abstract
