Living with Hereditary mucoepithelial dysplasia

A rare condition affecting skin, hair, gums, eyes, and lungs, starting in infancy.

Understanding Hereditary mucoepithelial dysplasia

Hereditary mucoepithelial dysplasia (HMD) is a condition that affects the skin, hair, gums, eyes, nose, and lungs.

Symptoms begin in infancy and vary in severity. The most common are hair loss, patchy red skin in the groin area, and red gums. Small skin-colored bumps and early cataracts are also common. Some people have eye disease that worsens over time, lung disease, and a rough, red tongue. GARD says intelligence is normal.

Signs & symptoms

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

  • Hair loss or thin hair
  • Red gums and gum overgrowth
  • Early clouding of the eye lens (cataract)
  • Sensitivity to light
  • Scarring of the lungs
  • Frequent respiratory infections

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 eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in SREBF1 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

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.
