Living with Familial renal hypouricemia

A kidney condition in which uric acid is very low in the blood and too much passes into the urine, sometimes causing kidney problems.

Understanding Familial renal hypouricemia

Familial renal hypouricemia is a kidney condition that leaves little or no urate (uric acid) in the blood because too much passes into the urine.

Many people have no symptoms. Some develop kidney problems, including kidney injury after hard exercise, with side and lower back pain, nausea and vomiting. The extra urate in urine raises the risk of urate kidney stones and blood in the urine. It can be found at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Kidney injury after strenuous exercise
  • Side and lower back pain
  • Nausea and vomiting
  • Uric acid kidney stones
  • Blood in the urine
  • Abnormal kidney function

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and kidney specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
