Living with Autosomal recessive Alport syndrome

A genetic condition that affects the kidneys, hearing, and eyes.

Understanding Autosomal recessive Alport syndrome

Autosomal recessive Alport syndrome is a genetic condition that causes kidney disease, hearing loss, and eye differences.

Most people have kidney function that slowly gets worse over time. Hearing loss from the inner ear (sensorineural) is common. The eye differences seldom lead to vision loss. About 15 percent of Alport syndrome cases are inherited in this recessive pattern. Onset is listed as childhood.

Signs & symptoms

GARD describes these main features:

  • Kidney function that gets worse over time
  • Inner ear hearing loss (sensorineural)
  • Eye differences that seldom affect vision

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 ear, nose, and throat specialists, eye disease specialists, genetic specialists and kidney specialists.

  3. Consider genetic testing

    Changes in COL4A4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
