Although PH1 may appear at any age, it most often presents during childhood. The median age of initial presentation is 5 years.

Patients with PH1 are at risk for recurrent calcium oxalate stones and nephrocalcinosis, which cause a progressive decline in kidney function. At the time of diagnosis, nephrolithiasis is often present.

Most of the signs and symptoms of the three types of primary hyperoxaluria are similar; however, ESKD tends to occur earlier and is more common in patients with PH1 than in patients with PH2.
