A 57-year-old healthy man had a plasma uric acid level of 0.2 to 0.58 mg/100 ml. The 24-hour urinary urate excretion was normal, at 797 mg. Urate clearance was 48% higher than endogenous creatinine clearance. Urinary xanthine and hypoxanthine levels were at the upper limit of normal. There was no evidence of phosphaturia, glucosuria, or aminoaciduria. A 10-year-old son of his maternal cousin had a plasma urate level of 1.2 mg/100 ml and a urate clearance equal to 42% of endogenous creatinine clearance. The findings in this subject could be accounted for by an isolated defect of tubular urate reabsorption or a tubular mechanism for urate secretion.
