Description: (OMIM) Papillorenal syndrome is an autosomal dominant disorder characterized by both ocular and renal anomalies, but may also include vesicoureteral reflux, high frequency hearing loss, central nervous system anomalies, and/or genital anomalies, consistent with the expression of PAX2 in ...
Clinical Description OMIM Rieger (1977) reported a family in which the father showed bilateral optic disc anomalies and died of chronic nephritis; his son showed macular and retinal abnormalities but renal function was normal, whereas his daughter had normal eyes but ...
Molecular genetics OMIM In a father and 3 sons with coloboma of the optic nerve and renal disease, Sanyanusin et al. (1995) identified a mutation in the PAX2 gene (167409.0001).

Diagnosis GeneReviews The diagnosis of renal coloboma syndrome (papillorenal syndrome) is based on clinical findings in the kidneys and eyes. Formal clinical diagnostic criteria have not been established....
Clinical Description GeneReviews Renal coloboma syndrome is characterized by hypodysplastic kidneys and optic nerve abnormalities (most commonly optic nerve dysplasia) with or without optic nerve or retinal coloboma [Schimmenti et al 2003]....
Genotype-Phenotype Correlations GeneReviews Some authors have observed that mutations in exons 7-9 result in renal hypoplasia/dysplasia and milder ocular findings [Porteous et al 2000, Nishimoto et al 2001]. Others have argued that renal disease results from a haploinsufficiency mechanism, while ocular findings are the result of dominant negative effects [Benetti et al 2007]. ...
Differential Diagnosis GeneReviews CHARGE syndrome. Renal dysplasia and retinal/optic nerve colobomas are major findings in CHARGE syndrome (coloboma, heart malformations, atresia choanae, retardation of growth and development, ear and hearing defects). Mutations in PAX2 were not identified in a small series of persons with CHARGE syndrome [Tellier et al 2000; Schimmenti, unpublished]. Sixty percent of individuals with CHARGE syndrome have mutations in or deletions of CHD7. ...
Management GeneReviews To establish the extent of disease in an individual diagnosed with renal coloboma syndrome, the following are recommended:...
