Living with Wooly hair-palmoplantar keratoderma syndrome

A very rare inherited skin and hair condition with woolly, thin hair and thick skin on the palms and soles.

Understanding Wooly hair-palmoplantar keratoderma syndrome

Woolly hair-palmoplantar keratoderma syndrome is a very rare inherited skin condition affecting hair, nails, and the skin of palms and soles.

People have thin, woolly scalp hair and sparse body hair, eyelashes, and eyebrows. Palms and soles are thickened in a streaked pattern, worse on the soles, and it worsens with age. GARD notes the heart muscle problem seen in similar conditions is absent.

Signs & symptoms

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

  • Sparse scalp hair
  • Sparse eyebrows and eyelashes
  • Sparse body hair
  • Thick skin on palms and soles
  • White discoloration of nails

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 genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in KANK2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Foundation for Ichthyosis and Related Skin Types may keep lists of experts for this condition.
