MFRP and microphthalmia: The panocular phenotype observed in patients with the nanophthalmos-retinitis pigmentosa complex (microphthalmia, retinitis pigmentosa, foveoschisis, and optic disc drusen) suggests that MFRP plays a wide role in eye development, functioning both as a regulator of axial eye length and as a critical molecule for photoreceptor function.
