Living with Spastic paraplegia-nephritis-deafness syndrome

A rare inherited condition with leg stiffness, hearing loss, learning challenges and kidney disease.

Understanding Spastic paraplegia-nephritis-deafness syndrome

Spastic paraplegia-nephritis-deafness syndrome is a rare, complex form of hereditary spastic paraplegia.

Leg stiffness gets worse over time, in varying degrees. It comes with hearing loss in both ears, intellectual disability and kidney disease that worsens over time (progressive nephropathy). GARD notes there have been no further descriptions in the medical literature since 1988.

Signs & symptoms

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

  • Stiff, weak legs
  • Hearing loss
  • Intellectual disability
  • Kidney disease (nephropathy)
  • High blood pressure
  • Speech difficulty

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 brain and nervous system specialists, ear, nose, and throat specialists, genetic specialists and kidney specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Spastic Paraplegia Foundation may keep lists of experts for this condition.
