Renal Tubular Disorders

Abstract

Kidney diseases that derive from the malfunction of the tubular portion of the renal nephron comprising the proximal tubule, loop of Henle, distal tubule and collecting ducts. These diseases can be common or rare and may have genetic or nongenetic causes and include cystic kidney diseases as well as disease caused by abnormalities of tubule ion transport.

Keywords: cystic diseases; ADPKD; ARPKD; fanconi syndrome; renal tubular acidosis; genes

(a) Schematic drawing of normal nephron segments. PCT, proximal convoluted tubule; PST, proximal straight tubule (pars recta); ThDL, thin descending limb of Henle loop; ThAL, thin ascending limb of Henle loop; TAL, thick ascending limb of Henle loop; DCT, distal convoluted tubule; CNT, connecting tubule; CCT, cortical collecting tubule; OMCT, outer medullary collecting tubule; IMCT, inner medullary collecting tubule. (b) Sites of cystic origin in autosomal dominant polycystic kidney disease (ADPKD). (c) Sites of cystic origin in autosomal recessive polycystic kidney disease (ARPKD).

Schematic drawing of some transporter proteins affected in diseases of (a) the proximal tubule epithelial cell, (b) the thick ascending limb of the loop of Henle epithelial cell, (c) the principal epithelial cell of the cortical collecting tubule, and (d) the intercalated epithelial cell of the cortical collecting tubule. Ad cyc, adenosine cyclase; ADP, adenosine diphosphate; ATP, adenosine triphosphate; AVP, arginine vasopressin; AQP2, aquaporin 2; PKA, protein kinase A.
