Living with Primary hyperoxaluria type 3

An inherited condition in which the body handles a substance called glyoxylate abnormally, causing kidney stones in some people and no symptoms in others.

Understanding Primary hyperoxaluria type 3

Primary hyperoxaluria type 3 (PH3) is a disorder of glyoxylate metabolism that can cause no symptoms or can cause kidney stones made of calcium oxalate.

It usually starts in infancy or childhood. Signs can include blood in the urine, frequent or painful urination, pain and calcium deposits in the kidneys (nephrocalcinosis).

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Kidney stones (calcium oxalate)
  • Blood in the urine
  • Frequent urination
  • Painful or difficult urination
  • Pain
  • Calcium deposits in the kidneys

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

Diagnosis

  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 eye disease specialists, genetic specialists and kidney specialists.

  3. Consider genetic testing

    Changes in HOGA1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
