A case of renal hypouricemia caused by urate transporter 1 gene mutations.
Hypouricemia is a common disorder in the general population. Herein, renal hypouricemia caused by human urate transporter 1 (hURAT1) gene mutations in a Japanese patient with intellectual disability is reported. She had compound heterozygous mutations in this gene (W258X and IVS2+1G>A), nevertheless, she showed no clinical manifestations such as urolithiasis and exercise-induced acute renal failure. Restriction enzyme analysis with HphI was useful to screen the IVS2+1G>A mutation in hURAT1 gene.
