Renal glucosuria due to SGLT2 mutations.
Isolated renal glucosuria results from mutations in SGLT2, which codes for an active transporter specific for d-glucose and expressed in the luminal membrane of the renal proximal tubule. In affected individuals, glucosuria leads to pursuit of hyperglycemia to exclude defects in glucose metabolism, and to investigation of renal proximal tubular function to exclude renal Fanconi syndrome. Here we present clinical and molecular data regarding a 19-year-old woman with isolated glucosuria. She was compound heterozygous for two SGLT2 mutations, i.e., a new missense mutation, T200K, and a known missense mutation, N654S.
