Living with Fibronectin glomerulopathy

An inherited kidney disease with blood and protein in the urine, high blood pressure, and protein deposits in the kidneys' filters.

Understanding Fibronectin glomerulopathy

Fibronectin glomerulopathy is an inherited kidney disease in which the protein fibronectin-1 builds up in the kidneys' filters (glomeruli).

It usually develops between early and mid-adulthood but can occur at any age. The deposits make the kidneys filter waste less well. Many people eventually develop kidney failure about 15 to 20 years after symptoms start. A kidney transplant can be an option, though the disease sometimes comes back afterward.

Signs & symptoms

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

  • Blood in the urine (hematuria)
  • Extra protein in the urine (proteinuria)
  • High blood pressure
  • Swelling in the legs (pedal edema)
  • Nephrotic syndrome
  • 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

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

  3. Consider genetic testing

    Changes in FN1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Should I have genetic testing for the FN1 gene?
How often should my kidney function be checked?
What should I know about transplant options?

InheritanceAutosomal Dominant
GenesFN1

Changes in the FN1 gene cause it. It is autosomal dominant, which means one changed copy of the gene is enough.
