Living with Piebald trait-neurologic defects syndrome

A rare inherited condition with patches of pale skin, a white forelock, balance problems, intellectual disability, and hearing loss.

Understanding Piebald trait-neurologic defects syndrome

Piebald trait-neurologic defects syndrome is a rare inherited condition that affects skin color and the nervous system.

People have patches of pale skin on the trunk and a white lock of hair at the front. They also have balance and coordination problems, intellectual disability of varying severity, and hearing loss that worsens slowly. GARD notes there have been no further descriptions in the medical literature since 1971.

Signs & symptoms

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

  • Patches of pale skin
  • White forelock or loss of hair color
  • Problems with balance and coordination (ataxia)
  • Intellectual disability
  • Hearing loss from the inner ear
  • Sun-sensitive skin

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 skin, hair, and nail specialists.

  3. Ask which tests can help

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