Highlights
- A novel heterozygous mutation in the SLC5A2 gene in a 2-year-old girl with severe asymptomatic glycosuria, mild failure to thrive, and subclinical hypoglycemia: Continuous glucose monitoring identified 14% hypoglycemic excursions (< 70 mg/dl), reduced at 1% with 1 g/Kg uncooked cornstarch at bed-time milk and eliminated (0%) adjusting the dose at 1.5 g/Kg, as shown by Flash technology.
