Living with Leukoencephalopathy-palmoplantar keratoderma syndrome

A rare inherited condition with thick skin on the palms and soles in childhood and brain and movement changes in adulthood.

Understanding Leukoencephalopathy-palmoplantar keratoderma syndrome

Leukoencephalopathy-palmoplantar keratoderma syndrome is a rare inherited condition that affects the skin and the brain's white matter.

Small thick spots on the palms and soles start in early childhood. In adulthood, a brain condition causes progressive stiffness and weakness in the limbs and a decline in thinking.

Signs & symptoms

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

  • Thick skin on the palms and soles
  • Trouble with thinking (cognitive impairment)
  • Muscle stiffness (hypertonia)
  • Unsteady walk
  • Muscle weakness
  • Slurred speech

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. Ask which tests can help

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

  4. Connect with expert centers

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