Presentation History A family history of consanguinity, early death, or renal disease is present in 67% of patients with nephronophthisis (NPH). [emedicine.medscape.com]

Presentation This results from gradual tubular injury. [ 1 ] Clinical features Polyuria - decreased concentrating ability with loss of sodium. Polydipsia. Growth retardation. Secondary enuresis. Renal impairment. [patient.info]

Infantile : bilateral disease due to cortical cysts with renal failure by 3 years of age; may have extrarenal presentation including retinitis pigmentosa, hepatic fibrosis, skeletal / CNS malformations, situs inversus, etc. [pathologyoutlines.com]

Some form of pigmentary retinopathy is frequently present although its age of presentation is highly variable. [disorders.eyes.arizona.edu]

• Liver Dysfunction

  Liver dysfunction has been reported in some patients but it is uncertain if this is coincidental or a part of the SLNS disorder. [disorders.eyes.arizona.edu]

  Liver enzymology, CT, and MRI of the upper abdomen gave no evidence of liver dysfunction. The ophthalmologic examination showed nystagmus, difficulty in nocturnal vision with severe visual impairment (1/10 of normal vision). [academic.oup.com]
