Optic nerve dysplasia and renal insufficiency in a family with a novel PAX2 mutation, Arg115X: further ophthalmologic delineation of the renal-coloboma syndrome.
Renal-coloboma syndrome, an autosomal dominant disorder associated with mutations in PAX2, is characterized by colobomatous eye defects, renal hypoplasia, vesicoureteral reflux, high-frequency hearing loss, and rarely central nervous system abnormalities. We identified a three-generation family with optic nerve colobomatous dysplasia and renal disease. We report the identification of a novel mutation in PAX2 in this family with renal-coloboma syndrome, Arg115X. We also report on the ocular and extraocular manifestations of PAX2 mutations for all cases of renal-coloboma syndrome reported to date.
