Renal glucosuria (RG) is a rare autosomal recessive condition characterized by renal glucose wasting in the absence of hyperclycemia or other forms of tubular dysfunction. The prevalence is unknown. It is caused by mutations in the SLC5A2 gene encoding the sodium/glucose cotransporter type 2 (SGLT2). RG is a benign condition with no symptoms or serious consequences, and does not require a specific therapy. |
