Incidental mutations (data from Mutagenetix , APF )
Homozygotes for a null allele show focal retinal lesions, loss of adherens junctions between photoreceptors and Muller glia cells, and light-accelerated retinal degeneration. Homozygotes for a spontaneous allele show background-sensitive retinal spotting, photoreceptor dysplasia and degeneration.
