Clinical Classification

Clinical Information

  • Gitelman Syndrome

    an inherited renal disorder characterized by defective nacl reabsorption in the convoluted distal kidney tubule leading to hypokalemia. in contrast with bartter syndrome, gitelman syndrome includes hypomagnesemia and normocalcemic hypocalciuria, and is caused by mutations in the thiazide-sensitive sodium-potassium-chloride symporters.
  • Autosomal Recessive Distal Renal Tubular Acidosis-4 with Hemolytic Anemia|DRTA4

    an autosomal recessive type of distal renal tubular acidosis caused by mutation(s) in the slc4a1 gene, encoding band 3 anion transport protein. additionally, it may be characterized by hemolytic anemia.
  • Distal Renal Tubular Acidosis

    failure of the renal tubules of the kidney to excrete urine of sufficient acidity, resulting in metabolic acidosis.
  • Gitelman Syndrome

    an inherited disorder caused by mutations in the slc12a3 gene. it is characterized by deficient reabsorption of electrolytes in the distal convoluted tubules of the kidneys. it results in hypochloremic metabolic alkalosis, hypokalemia, hypocalciuria, and hypomagnesemia.

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Patient Education

Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.

Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include:

  • Cancer
  • Cysts
  • Stones
  • Infections

Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.
