Clinical InformationClinical

  • Glycosuria

    the appearance of an abnormally large amount of glucose in the urine, such as more than 500 mg/day in adults. it can be due to hyperglycemia or genetic defects in renal reabsorption (renal glycosuria).

  • Glycosuria, Renal

    an autosomal inherited disorder due to defective reabsorption of glucose by the proximal renal tubules. the urinary loss of glucose can reach beyond 50 g/day. it is attributed to the mutations in the sodium-glucose transporter 2 encoded by the slc5a2 gene.

Patient EducationClinical

Amino Acid Metabolism Disorders

Metabolism is the process your body uses to make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Your digestive system breaks the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body.
