Living with Arrhythmogenic cardiomyopathy with wooly hair and keratoderma

A rare genetic syndrome with woolly hair, thick skin on the palms and soles, and a weakened, stretched heart muscle.

Understanding Arrhythmogenic cardiomyopathy with wooly hair and keratoderma

Arrhythmogenic cardiomyopathy with wooly hair and keratoderma is a rare genetic syndrome that affects the hair, skin, and heart.

Woolly hair is present at birth. Thick skin on the palms and soles (palmoplantar keratoderma) develops in the first year of life. Dilated cardiomyopathy, where the heart muscle stretches and thins, mostly on the left side, develops in childhood and can lead to heart failure. It is an ectodermal dysplasia.

Signs & symptoms

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

  • Woolly (kinked) hair from birth
  • Patchy thick skin on the palms and soles
  • Stretched, thinned heart muscle (dilated cardiomyopathy)
  • Heart failure in some people

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, gum, teeth and mouth specialists, heart and blood vessel specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in DSP 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

    Children's Cardiomyopathy Foundation and National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.
