Persistently high urine glucose levels caused by familial renal glycosuria.

Persistently high urine glucose levels caused by familial renal glycosuria. Arch Pediatr. 2020 Aug 15;: Authors: Djeddi D, Cauliez A, Oulebsir A, Hureaux M, Vanrenterghem A, Vargas-Poussou R Abstract Glycosuria generally occurs when the threshold for glucose reabsorption by the proximal renal tubule is exceeded or when reabsorption of filtered glucose is impaired. Although the discovery of glycosuria in a child will prompt screening for diabetes mellitus, it is also a sign of a rare tubulopathy called "familial renal glycosuria" (OMIM #233100). This tubulopathy is linked to a defect in the sodium-glucose co-transporter 2, encoded by the SLC5A2 gene. Here, we describe and discuss two pediatric cases in whom familial renal glycosuria was discovered fortuitously after the observation of persistently high urine glucose levels in the absence of hyperglycemia.
