Clinical InformationClinical

  • Fanconi Syndrome

    a hereditary or acquired form of generalized dysfunction of the proximal kidney tubule without primary involvement of the kidney glomerulus. it is usually characterized by the tubular wasting of nutrients and salts (glucose; amino acids; phosphates; and bicarbonates) resulting in hypokalemia; acidosis; hypercalciuria; and proteinuria.

  • Acquired Fanconi Syndrome

    fanconi syndrome caused by exposure to noxious agents.

  • Nephrocalcinosis

    deposition of calcium in the renal parenchyma, resulting from high levels of calcium in the blood and/or urine.

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.
