Living with Glomerulopathy with fibronectin deposits 2

A family-linked kidney disease with protein and blood in the urine and high blood pressure that can lead to kidney failure in adulthood.

Understanding Glomerulopathy with fibronectin deposits 2

Glomerulopathy with fibronectin deposits 2 is a disease that runs in families and affects the kidneys.

It causes protein to leak into the urine, blood in the urine, and high blood pressure. This can lead to kidney failure between ages 20 and 50. Kidney tissue under a microscope shows glomeruli (the kidney's tiny filters) that are bigger than normal and have deposits of fibronectin, a protein that helps cells stick together.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Protein leaking into the urine
  • Blood in the urine
  • High blood pressure
  • Nephrotic syndrome (heavy protein loss in the urine)
  • Reduced kidney function

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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