Description : Renal hypouricemia is characterized by impaired uric acid reabsorption at the apical
membrane of proximal renal tubule cells. The syndrome is not lethal and may be asymptomatic.
However, it is accompanied by nephrolithiasis and exercise-induced acute renal failure
in about 10% of patients (Ichida et al., 2008).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the solute carrier 22 (urate transporter), member 12 gene (SLC22A12,
607096.0001);
Laboratory abnormalities : Hypouricemia; Increased urinary urate; Increased fractional excretion of urate (greater than 50%);
