FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

PHENOTYPE: Mice homozygous for a knock-out allele display progressive retinal photoreceptor degeneration along with significantly reduced a- and b-wave amplitudes, and a moderate but nonprogressive high-frequency hearing loss associated with widespread loss of outer hair cells in the basal turn of the cochlea.
