A Novel Mutation Confirms MFRP as the Gene Causing the Syndrome of Nanophthalmos-Renititis Pigmentosa-Foveoschisis-Optic Disk Drusen

We confirmed that the syndrome of posterior microphthalmos, retinitis pigmentosa, foveoschisis, and optic disk drusen constitutes a distinct autosomal recessive entity. The novel frameshift mutation identified in the family described here validates MFRP as the gene responsible for this particular disease, which characteristically involves structures located at the posterior segment of the eye.
