title: Renal hypouricemia due to an isolated renal defect of urate transport.
abstract: A 22-year-old man was found to have low serum urate concentration (1.1-1.7 mg/dl). His urate clearance was markedly increased (26.9-35.5 ml/min) and was not decreased after administration of pyrazinamide, but was even more increased after administration of benzbromarone. No other renal tubular abnormalities were detected. The young man has one sister and two brothers. His sister also has hypouricemia and hyperuricosuria. We suggest that the present case had a genetically determined renal abnormality affecting tubular presecretory reabsorption of urate.
