Living with Radio-renal syndrome

A rare syndrome with differences in the arm and hand bones and the kidneys, present from birth.

Understanding Radio-renal syndrome

Radio-renal syndrome is a rare developmental condition with limb differences in the arms and kidney differences, present from birth.

People may have missing or underdeveloped fingers, radius, or ulna bones, short stature, mild ear differences, and a missing kidney or a kidney in an unusual place. GARD says it hasn't been described in the literature since 1983.

Signs & symptoms

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

  • Missing or underdeveloped fingers and forearm bones
  • Missing or underdeveloped kidney
  • Kidney cysts or abnormal kidney development
  • Small lower jaw
  • Breathing difficulty
  • Short stature

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 bone and joint 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.
