Living with Tall stature-intellectual disability-renal anomalies syndrome

A rare overgrowth condition with tall stature, large hands and feet, developmental delay, and kidney differences.

Understanding Tall stature-intellectual disability-renal anomalies syndrome

Tall stature-intellectual disability-renal anomalies syndrome is a rare overgrowth condition with tall stature and developmental delay.

People have large hands and feet with large thumbs and big toes, and spatula-shaped fingers and toes. Babies are often larger than typical at birth. Intellectual disability, hearing loss, heart and kidney differences, and distinct facial features can occur. Signs may begin during pregnancy or in the newborn period.

Signs & symptoms

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

  • Tall stature
  • Large hands and feet
  • Intellectual disability and delayed development
  • Large head
  • Kidney differences
  • Heart differences

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, genetic specialists and kidney specialists.

  3. Consider genetic testing
