Isolated Glycosuria in a Child in Sri Lanka

Renal glycosuria or benign glycosuria is a rare autosomal recessive condition where glucose is excreted from the urine while having normal serum glucose levels, as a result of a defect in low affinity sodium glucose transporter (SGLT2) in the proximal convoluted tubule (PCT) of the nephron. Benign glycosuria or renal glycosuria has been described as an autosomal recessive disorder. It is usually benign and most of the time asymptomatic and considered as an incidental finding. However, childhood glycosuria is associated with many other tubular disorders such as an Fanconi’s syndrome, Cystinosis, Wilson’s disease, Lowe’s syndrome, Tyrosinaemia and the initial presentation of childhood diabetes mellitus
