Figure 1. Diseased kidneys.

Most cases of PH1 are diagnosed during childhood; among patients who present as adults, recurrent kidney stones and mild to moderate reduction in kidney function are the most common presentation.

Normal kidney function does not exclude the diagnosis of PH1. Many patients present with symptomatic nephrolithiasis in addition to normal or reduced kidney function.

Most patients are symptomatic at diagnosis, but some patients with a family history of PH1 may be identified before the onset of symptoms.
