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.
constellation of clinical and laboratory manifestations produced by generalized proximal tubular insufficiency in the presence of normal, or nearly normal, glomerular filtration.
A genetic or acquired disorder characterized by impairment of the function of the proximal tubules of the kidney. It results in decreased reabsorption of electrolytes, glucose, amino acids, and other nutrients.
