DOI: 10.1080/13816810.2022.2103835

Abstract: ABSTRACT Background Membrane frizzled-related protein (MFRP) plays a critical role in ocular development. MFRP mutations are known to cause nanophthalmos and, in some cases, retinitis pigmentosa, foveoschisis, and/or optic nerve head (ONH) drusen. The broad… read more here.
